Openbox S10 keeps rebooting

[rrob311]

My S10 will reboot every time you try to drive a motor with it or when viewing HD channels with lots of movement DVB-S2 especially. Some folks have discussed in the past that this is due to a poorly built power supply. I was not able to find the parts to fix this so I am taking Pixl's advise and I ordered a complete power supply from China for about 11 dollars. Hopefully it shows up soon so I can install it and then finally try to use this receiver. Luckily I am into this receiver for about 50 or 50 bux after the power supply so hopefully it works out so I have a decent backup receiver for feed hunting.

Once you replace the power supply add a $7 plastic noise free small fan on top 24/7, beleive me that make a lot of improvements on mines.

p.d.
have you replace the resetable fuse from the main board as per pixl instructions??? They're cheap and make a lot of improvement $3.99 w/free shipping for 10 pieces

I would check the firmware rev

Carlos,

I have reservations about those polyfuses from China. That is where the crappy ones came from in the first place. The replacements from Digi Key are made by well known brand Little fuse made in Korea. They cost $0.58 + $2-3 shipping. Do you really need 10?

the hd reboot was a symptom on old firmware

on a side note with the s10,I was trying to fix my tuner and noticed the xtal leads on the tuner were dangerously close to shorting out against the metal on the cam socket.I took a pair of cutters and trimmed those leads and other cap leads that were way too long.In one instance before I cut them, the leads did short out.If you pop the tuner out to put in a varistor,check the lead lengths on the bottom of the module.

Agree with you, I got mines from Digi Key, I think they also has a minimum quantity but cant recall the quantity. So here theyre 2 choices to get the parts from. As you mentioned Digi Key will be the best choice

Here is the link to the Digi Key part as reccomend from you

I will post my findings once the power supply gets here and I install it.

[rrob311]

Well I got the power supply for the S10 today from Yojia and I installed it. The chips on the new supply looked the same as the old one. I am still unable to drive the sg2100 motor with this but I have been watching a few channels with the box not using the motor function and it hasn't rebooted otherwise. I would like to make it so this box will be able to move the motor but I have 4 dishes setup right now without motors so its not a total necessity. Maybe there is another firmware I should try. I haven't done anything else with the box other than switching out the power supply.

Probably old firmware

[el bandido]

Rebooting can be caused by an antenna short or overload.
Motors do not normally draw much current, usually less than a lnb except for a brief moment at start-up.
Several times you have been asked about the firmware. You might want to post what firmware you are running.

Have you tried disconnecting the lnb and turning the motor?

[dr.zin]

time for newer firmware I think.
At least 10-10-2011

[rrob311]

The motor runs fine with all of my other STB including my Openbox S9.

[rrob311]

I just caught a feed on 91w at 11952h 13231SR that makes the box constantly reboot. I am going to try a different firmware and take it from there.

[rrob311]

I just loaded the 11-10-22 firmware and the problem is the same. Instantly reboots as soon as you try to drive a motor or if there is an HD feed with a lot of movement in the picture.

hey rob the pixl fix is whats missing here if you did not look and replace that one piece thats probably your problem i have an open box s9 i had to replace mine i dont use it to drive the motor but from a lot of reading your symptons are also fixed by replacing this pixl piece ...

for me my issue was id be on a h transponder and anywhere between 2 and 10 minutes id loose quailty i have to power down to get the quailty back... i have 17 fixed lnb on 3 dishes i kept thinking short somewhere to switch to wire are bad everything i could try to solve this issue then i read pixl thread and others folks ...


as soon as i replaced the piece my box is fixed no more loosing quailty/ freeze i have read others had motor issues and re boots and once they replaced it there box was fixed go open your box put the cover back no screws run unit when the problem kicks in unplug box take off cover feel piece inside box see if its real hot....

[rrob311]

OK I will see how hot this piece on the board is getting. I haven't replaced it but it wont drive the motor to save its life. It would be nice to get this box going so I have a good spare.

[rrob311]

I noticed the suspect part on the power supply is the same on my new one. When the receiver reboots the power resets for a second so I am assuming the power supply is resetting the box. I am going to attempt to track down the 4844 part and solder it into the power supply and go from there.

[rrob311]

I found the SD4844 chip on Ebay so I am going to order a couple of them and hopefully get this box to work.

[rrob311]

I got a pair of SD4844p chips and I am soldering them one in tonight. Hopefully this fixes it.

[cpr43]

Great , keep us updated!!

[rrob311]

OK I soldered the chip in and put it back together and NOW MY MOTOR MOVES. So this is what fixed it! This other fix should be made into a sticky next to the thermistor one. Big thanks to Pixl for letting me know about the chip that is underrated. I never would have figured that out in 1000 years.
