s9 loosing quailty after a while and or frezzing on certain boxs/ channels pixl might have found a fix

[TunaDude]

hello all you s9 and maybe s10 folks i have an open box s9 i have had issues with h transponders working for a while then droping off / loosing quaity and even locks up and i have thought it might be my set up(all ku 16 lnb's total 3 dishes) i have tried everything to beat this problem and today reading around i belive the problem has been solved my a dude named pixl i dont think he is a member here but a post he did at fridge about low voltage problem for the s9 hits the mark right on the head for me and others here.


on my s9 i have this issue where on mainly the circular lnbs i aim at 61.5 77 110 for the hidden locals we get when ever i am on a H TRANSPONDER using the regular ole dtv/dish network style lnb's after from 2 minutes to around 10 i loose quailty and if i try to go to the rest of my ku sats i have no quailty i have to reset the button in the back and even that somtimes dont reset it i have to go into menu and hit lnb power off exit out then re put it on and then everything is reset but when i go back to the circualr lnb,s it craps out again after a couple of minutes .

it dont do this for the linear lnb's i use althouhg somtimes it has froze on a linear lnb but not like the circualr lnb my guess is circual uses more umph power

now on my 119 lnb i have a invacom quad 031 i use the circualr side of it. on this one lnb it never craps out it holds the h transponder 2 mintue 10 minutes 3 hours find and dandy so my guess is the invacom is more like a linear lnb all around and doesnt cause the lnb voltage problem in my s9 like the other circualr lnb's i have .

as a test to see if its not old circualr lnbs being bad my brother in law had 3 brand new lnb never used zinwels i ran them straight with out disec swithces and nope still had the same troubles of loosing my quailty on h transponders after 2 to 10 minutes... v transponders never seem to frezze.


then i read this post at fridge from pixl not to take away from this great site.

he found out a problem on the s9 here is a little i copied.

Something else I have noticed over the past 2 weeks is that my S-9 blind scan seems to be going blind. By this I mean it seems to be missing most tp's. As an example, if I blind scan 72W C band and Ku band, my S-9 does not find a single tp or station but the ones that were previously there are still working. If I delete one channel and keep the others on the same tp, then do a blind scan, the one I deleted is gone. Starting to look like this box is about to expire or maybe there is something I am missing.

TunaDude, I review the fta receivers that I get. Unfortunately all of the receivers I get are not excellent pieces of electronic equipment. I try to be fair and post truthfully about what I find in fta receivers.
For most people, it is cheaper to replace a broken or wounded S9 than to pay for repairs. Very few people have the ability to do what you are describing. Also, will the repair fix every S9 receiver? I don't think so. Try it on yours and post the results for us. It would be nice if you can fix yours for a dollar, and this would encourage others to try it!!!

Hi Guys,

I don't stop by at this site very often but today I found I was being talked about, nice for a change. Ha. Thank yo TunaDude for the kind words.
Here is what I found on the OpenBox S-9 when I got a couple of guys to send me their broken S-9s to compare with my working one.



I've traced the problem of low LNB voltage that causes the S-9 to work for a while then
drop off. There is a small part that looks like a disc capacitor near the tuner that actually
is a PTC thermistor that goes bad.

[Only registered and activated users can see links]

This part provides short circuit protection, but when bad it trips off at loading well under
the max rating of 500ma. The two bad ones I have found so far are marked M60 065.


[Only registered and activated users can see links]


On my own OpenBox that is still working, this part is larger and is marked JK60 065.
Digi-Key engineer crossed this to a "Little Fuse" brand part # F1993CT-ND.


[Only registered and activated users can see links]

This part can be changed from the top side of the board. Just snip the old one off.


[Only registered and activated users can see links]


Then tack solder the new one to the solder pads.


[Only registered and activated users can see links]

I then tested the S-9 by operating into a variable power resistor.

Pixl, this information is much appreciated! Hopefully somebody can use it and will post about it.
I doubt it fixes all of them, but I bet it fixes a lot of them. Thanks for taking the time to post your solution here. EB

[TunaDude]

glad to know pixl is or can post this same info here if he wants as a member. my s9 was drviving me crazy trying to figure out why this is going on i have changed everything one can think of except thinking it was the box? this pixl has been messin around for a while trying to figure out what was going on with the quailty level droping out after 2 min or as much as 20 minutes i have read many posts with frezing droping in januray he had a post as well about it but at that time didnt know yet he was trying by testing stuff


as far fixing all the s9 or s10 that have issue like mine with this one 89.cents piece i hope it does especaily folks like me who aim at the dn sats using circular lnb's and wonder why in less than ten minutes it gets stuck and looses quailty...


of course this little disc piece that pixl figured out has since been changed in new boxs so that means many out there can fix there box by doing the repair im not the best at soldering but from his pictures it dont look to hard to get to and opening the box is not hard to do and as far as the warantee ha ha there one has to send in the guts of a box from wht i read not just send in your box so somone would know how to take out the main board and then there is customs in china

so i will report back on my success or if i goof up like i said it dont look to hard to snip out the old one and drop soldier the new one in.


its easy to see which one to do and there is enough space to try im pretty sure it will work because like pixl wrote when you loose quailty after its been on for the 2 5 or 10 minutes before it shits it self out you go feel that peice and its hot i mean hot! and if i leve it on the same 61.5 sat on a non h transponder for 2 5 10 20 3 hours tht disk peice is not hot.


so for what ever reason certain sat signals might cause that one peice to heat up in the open box could explain why folks freze from c band to ku band again for me all my ku sats i aim at thats 72 83 85 87 89 91 93 95 97 99 103 105 and 61.5 77 110 119 for the hidden stuff all hooked up with 0ne 8 disec and then i use 3 regualr 4 disec are all fine and dandy on h on v if i leave it on for 5 minute or 5 hours except for the dish circualr lnb these cause the peice in the open box to shit it self and quailty gone except my invacom 031 this lnb has linear and circualr i use the circualr side for 119 and it dont loose quailty? maybe cause it uses less umph?

so with that said somthing in a circular lnb is i guess puting to much of a load on this weaker peice in the open box and bam quailty gone and frezze and who knows on other sats folks aim at maybe thats whats going on could be a slight frezze like i read on some cband but since i dont do c band i cant speak if easyconfused tried this fix then maybe we would know on cband he is posting with this pixl dude at fridge ...

[easily confused]

Just wanted to point out that, if anyone has an issue with blind scan not working, try using preset scan. I was advised of this by PixL and it found all tp's and channels that had been there before that were not being found in blind scan

[TunaDude]

glad its posted here to i missed he posted this before i wrote today with those pictures see its not that hard to find there is numbers on that yellow disk thing and one can match it up

[Guest]

That's good for the tp that have been previously scanned in but what about new ones or wild feeds? I find all 3 of my ali chip receivers about the same- that's why I am also using an azbox and pansat 9200, they don't miss a thing.

[el bandido]

OK.
The post by Pixl has been moderated and I do not know why. We do not normally moderate posts here. Let me see what has happened.

[el bandido]

The live link may have kicked it into moderation.
Anyway, you should be able to see it now. EB

[TunaDude]

i wonder if one can go to radio shack and find somthing? like the part number
Digi-Key engineer crossed this to a "Little Fuse" brand part # F1993CT-ND.

since it a fuse ?

[dr.zin]

you have questions,they have blank stares.
It is actually a thermistor,mail order the only way to go.
I got the blank flash chips from digikey,they charge sales tax so don't forget to include or they will harass you for 59 cents.

That's why I am watching these new boxes being tested. I know they cost considerably more but I am hoping they prove to be far superior in quality and longevity.

[el bandido]

Some of the new receivers are probably not going to cost much more than a S10. Let's wait and see.
In the meantime, any information on fixing an Openbox is appreciated.
One Openbox problem I would like to see a solution for is when the receiver displays ON, or ----, and you cannot communicate with it through the rs232 or the ethernet port. I suspect the flash chip has been damaged when this happens.

[dr.zin]

loader v2.0.0c will fix any dead receiver unless it has a red light only showing,that is a hardware problem.
Clone kill ff's out the bootloader section of flash and the 1st 64k of app area and you can still recover via rs232.
You must use v2.0.0c not newer or older.It must be the version that had eromclient.abs of 56k.Smaller .abs were for older processors.
A bogus version of 2.0.0c was just a renamed 2.0.0b and has no eromclient.abs file included.
You can't brick the s9 or s10,the processor has code to keep the rs232 port working even with a blank flash chip.

[el bandido]

I agree Dr. Zin but some of the S9 receivers I have seen, the rsr232 and the ethernet port do not work. The receiver displays ON and you cannot connect to it. If you have a hardware solution for that, please start a thread on it. Thanks. EB

You could just cut this part out and jump the connection and the receiver would work. BUT.. you will have no short circuit protection for your coax. Most of us short out the coax briefly when mating up F connectors. Also you could put a 1/2 amp fuse in place of it. BUT.. you will have to open up the receiver and replace it every time a shot occurs. The thermistor is self re-setting.

[dr.zin]

the generic schematic shows it as part of an overload circuit,it may not be as simple as just a fuse in series with the output.

Well that could be true. I'd rather see people put in the replacement part the Digi-Key engineer came up with.

[TunaDude]

as an idea inside the pansats 2500 2700 3500 they all have the yellow piece looks the same the captive works 600s as well on the pansats they all use TOP LINE B
second line RO65
third line 4 random numbers like the chip count

i have 2 2500 pansats one 2700 one 3500 all have the same except the third row of numbers on 2 of the 2500 bouhg at the same time the third number is 4149s on one and 4121 s on the ohter so thats why im thinking the third row of numbers on these things is the number count like the first one made second one and so on

on the captive works 600s the numbers are WH60
065 thats it of course my yo ho dyas are long gone no more johhny dep tv so to speak and non of these units i use anymore but if i was to try to switch one id kind of go for the captive works one cause it looks the close..\\\


and now that i have looked inside every box i have the pansats sure look a lot like the open box on the inside chips and all power board etc the captive works 600 and 800 look like a traxis 3500 set up and all not to much in there compared to say the pansats but like i said the 800cw dont have this y ellow disk and the traxis also dont have the well not in the form im looking for not to say they have some other thing in there that does what the yellow thing does... either way


thank you pixl for taking the time to fix this and showing folks a step by step there are many who cant just fork out 100 200 each time somone comes out with a so called better box....

[dr.zin]

schematics of old brands show mostly 065 or 65 like rx65f,rxe065,t60 065 one oddball was 60vrj2n
they show as in series with the power out like a regular fuse circuit.

[TunaDude]

Thank you PIXL ! ! ! ! ! for spoting the trouble area of my box the s9 open box my box was getting worse i noticed this yesterday instead of only h transponders getting stuck and droping out my 119 v transponders started to do the same thing maybe cause when i tried to read the chip i was moving it around to read those tiny numbers and quite a few times id check the inside to feel if its hot and squeze it and it was burning either way i took a bold chance and removed the one inside the open box.


Instead of getting the replacment one from digi i sniped out the one from my cw 600s premium it looked like the one in open box and the numbers was close

open box was W60 65 the captive works WH60 65 I had pansats to they also looked close but had a R in front of the bottom R65 that made me say go for the captive works its almost a match and used the one from the captive works.


and i ran it on 110 circular first on the only channel itc hidden left i on marsha marsha brady for 15 minutes! inspration channel hidden pid.


the record on that station has been 2 minutes before it craps with the bad one inside the open box then went to 119 on the v after 8 minutes i said k then as im sitting here the only one on 61.5 h transponder that shits it self in abbout 2 to 5 minutes is still going strong for over half hour. ! ! !

I took the risk because after all deep down inside i am a legit tester now lol and didnt like the problem of my open box getting worse and the ole cw can be saved if i want to add a new one i guess i will by the five from digi as a just in case use one on my captive works and keep the other four in case i need it if that one to goes bad ! very happy folks!



to all who might try your older boxs like did i just think i got lucky not sure what other boxs use besides the pansats but if its close to where the other one is in your open box looks the came yellow with numbers maybe somone knows here that as long as certain numbers are there i guess like mine being so close its a good swap. of couse i hope im not editing this in a few days cause it died on me lol


but i fell its gonna be fine!

[dr.zin]

Maybe take current readings on the working setup,if you have the capability.

[TunaDude]

ok current readings ! it works ! it still works !you asked me at 736pm. its 1047 pm when i wrote this post and 1150 am saturday moring when im editing this post to say its still works! no freezez lost of anything seems to find a few more thing in blind scanning unless its just dumb luck thing are showing up on friday but over all YIPPEEEE! FIXED FIXED FIXED FIXED FIXED DID I SAY IT WAS FIXED! sat 3 17 12 pixl get the genius of the month award in my book !

i know how to check voltage. just dont have a voltmeter i have had my open box 10 months now my issues are gone. i can leave it on any of the 4 dn sats now on h on v go 2 min 5 min 10 20 30 2 hours etc.

only thing is the hidden one on 110 inspration tv does freeze the show but the comercials run fine..

somthing is up with the way its being sent its like the motion of the video doesnt seem right and it freeze although ealry in the day it was the brady bunch on 110 and it was fine


i have to leave that issue with the way dh sends out the show it was the waltons and when the commercial came on all of them played fine no frzze no slow motion like the waltons seem to be jsut guess the open box dont agree with the 70's tv show from dn ,,,

good luck to anyone who gives it a shot i didnt find it to hard to do.

[Pixl]

For those of you wanting to salvage a thermistor out of old equipment, here is some info the Digi-Key engineer gave me about the part numbers.
The first letter or two is the manufacturer.
The 60 = 60v. max.
The 065 = 650 ma. holding current.

Of course there will be some out there that don't follow this format.

[TunaDude]

Thank you again pixl then that makes my one from the captive works an exact match but made from a differnt manufactuer my captive works never gave me any issues ...

for the pansats line there is only one number the 065 which we now know is for the The 065 = 650 ma. holding current. there is no top line number except a B The 60 = 60v. max and the bottome numbers are id numbers a 4 digit number 4123 4124 etc but getting back to

the first missing The 60 = 60v. max number? and since all my pansats had a B on the first line and since i dont know squat if i was mcguyvering this id say the b stands for 60v?? just pansats used these and the rating was a letter B???? like A could be 90v B are 60v c are 30v of course what do i know thats why i didnt use a pansat one and the cw was and is still kicking ass as i type only issue is on 110 inspration after like minute on some shows it frezze still hear sound though and still have quailty so i dont know the comercials dont miss a beat when there on and when i first tested this out your idea of replacing the thermistor the brady bunch was on and it went 15 minutes and i said ok next one to check etc... so my issue with 110 on inspration has to be from there end and my open box getting cauhgt up trying to play it? like i have read maybe a memory issue .. or older shows it happen on the waltons to.. but no lock outs no loss of quailty any more no having to mess with the button inj the b ack or turn on turn off lnb in menu..... again YIPEE YIPPE IM AN OLE HIPPY


so folk who have there extra boxs are gonna benfit to like me thats cool id wait on the pansats till one knows if the B is the 60 missing in this equation? also for the record you cant take out the resitor hook up to to ends turn it on and except it to work it dont lol.. no quailty on anything needs tohave the yellow thing in there'!

[ViP3R]

Nice thread and great info Pixl! all you guy's are giving some very nice help here.. :th_thumbs20up:

[TunaDude]

very nice thread if i had to count how many hours i spent from disecs to wires to lnb's i have combo of universal linear standard linear and circular this problem on the s9 and s10 if i was al of you id get a set of the parts from digi i bought 5 today even though my box is fixed with the one i took out from the cw 600 i just want to fix that one and have 4 more and maybe one day down the road i can mail someone one or if i maybe pick up a used open box that has the issue anyway not only did Pixl tell us what why and where this disk capictor was he provided us with the 89.cents fix

Pixl is the .89 cents man plus shiping and sales tax
