OS MIO 4k no signal after Edison screen

[brct203]

I tried that settings file, didn't seem to make a difference

Also tried 4 different HDMI cables, didn't seem to make a difference

During that test, I ran into another interesting observation:
my TV has 2 HDMI ports. One is labeled HDMI1, the other is HDMI2/DVI

on HDMI1, I can run at 480, but when i tried to switch to 1080p, I get black screen. I tried openVIX there and it was working at 1080, but sudenly the screen went black saying no video signal

on HDMI2/DVI, I can switch the video in TNAP to 1080p and I get a picture, just not on initial boot. And OpenVIX seems to display 1080p reliably even on a fresh boot.

Port HDMI1 on the TV works fine with a PC at 1920x1080

weird, right?

note that this video problem started with the receiver connected to another, older TV through an HDMI switch (which we are still using without a problem with our Roku)

also, I noticed in the setting file, the first line in the one from openVIX is config.av.videomode.HDMI=1080p while in TNAP it's config.av.videomode.DVI=1080p
would that have any importance?

Thanks

Yes.
You may change settings file to config.av.videomode.HDMI=1080p and see if it helps. Just remember: init 4, then edit, init 3.
If enigm2 is not stopped using init 4, then your settings edit will fail.

ok that didn't make a difference

I have now moved the receiver back to its original location, connected to my older Sony TV, and there it won't display anything above 720p through my HDMI switch, and nothing at all if I connect it irectly to the TV without the switch

My guess is that something at hardware level is not right with that HDMI port, but it's not completely dead and it works in some very specific cases that depend on the image and also on the TV/port on TV :-(

Is there a way I can clear all images, in case there's some corrupt video driver that gets somehow stuck in there? When I ran your recovery image, it overwrote slot1, but the TNAP4.1 I had in slot 4 was still there.

[el bandido]

Terminal (or putty) is the easiest way to do this.
Telnet to the receiver. Slots are as follows:
mmcblk1p9 = 4
mmcblk1p7 = 3
mmcblk1p5 = 2
mmcblk1p3 = 1

As an example, To clean slot #4, enter the following in terminal:
dd if=/dev/zero of=/dev/mmcblk1p5 bs=1M count=1

You may also mount the files system for slots and adjust the files or read the files or do other things that need file access.
Examples:
mkdir /media/slot4 && mount /dev/mmcblk1p9 /media/slot4
mkdir /media/slot3 && mount /dev/mmcblk1p7 /media/slot3
mkdir /media/slot2 && mount /dev/mmcblk1p5 /media/slot2
mkdir /media/slot1 && mount /dev/mmcblk1p3 /media/slot1

great thanks
and after that I should be able to reload the PLI recovery image that you sent and then TNAP from there, right?

[el bandido]

The Recovery image will only load in slot one. You may manually erase the other slots, or I think you can load a recovery from OpenVix that will erase the other slots automatically. But any recovery image for the MIO should only load in slot 1.

[brct203]

ok I ran those dd commands on all 4 slots while I was running the image in slot 4

now i've powered it up again with the recovery image on the USB dongle, but nothing happens, all I get is EDISION on the box front pannel display, but no video, nothing

[brct203]

never mind, I changed noforce to force and that worked

[el bandido]

Great that you got it working!
Sounds like you were in slot 4 and deleted the image or operating system for slot 4? So when the receiver booted, it returned to slot 4, which was empty.
Slot 1 is the main slot. It is a good idea to be in slot 1 if you are going to delete the file system for the slot you are using!
