Re: Vizio E500i-A1 Monochrome (black & white) image

Tried erasing eeprom, it doesn't turn on this way...
This is clearly a software problem, can anyone help to find the eeprom dump for it?

Hello, I have a very weird issue with my Vizio E500i-A1. It works well except it only shows monochrome (black & white) image. TV signal is b&w, all HDMI inputs are b&w. At the same time the TV menu is colorful. Of course I tried to change color/saturation settings, it doesn't have any effect.
I tried to do factory reset. The TV setup screen was colorful, however it didn't help, all inputs are still showing b&w picture.
Checked voltatges on MB and all seem to be fine.
UPDATE: tried to play an .avi file via a built-in media player. The media player menus are colorful,...

This is a dumpster find, don't know if it was hit, there are no visible cracks...

I though there may be something wrong with the panel voltages.
Those I managed to find on the T-Con board. Does it seem normal?
12V: 12.27v
VCC33: 3.28v
1.2V: 1.25v

Hello everyone, I described the symptoms and measurements [URL="https://www.badcaps.net/forum/showpost.php?p=1197276&postcount=47"]here[/URL]
It seems I tried everything, my last idea is that the eeprom or firmware (or both) may be corrupt.
I'm not able to find eeprom and firmware dumps in open sources.
Hoping someone here has access to closed forums or manufacturer's service center resources and can help get those dumps? Hello everyone, I described the symptoms and measurements [URL="https://www.badcaps.net/forum/showpost.php?p=1197276&postcount=47"]here[/URL]

Re: Toshiba 46sl417u main board issue

Hello everyone, I'm reviving this old topic and this is my first post here. I'm in need of your collective wisdom...

I got 55SL417U - same TV, bigger size. Similar sympthoms:
After I plug it in I see 3 blinks of a green led. In a few seconds the backlight comes on (sometimes it does not). And then nothing. A back-lit black screen, no sound. Can turn it on/off with sensor buttons or a remote.
I found several topics about this TV here and seems none managed to fix it. Replacing the MB is not an option as it is too...
