If you have ExLink (and you`ve set rs232 to debug), you can change any setting back. Also for unbricking we need exlink debug output.
I can`t see anything useful on this picture, resolution isn`t enough.

You should explane what did you do step by step before tv bricked...

Bad... really bad...
The resolution is too low because i can't upload a bigger picture (forum rules - max resolution allowed is 800x600).
Why don`t you use external picture storages like tinypic.com ?

Can you see the chip labels on the photo? Me not.

Anyway, honestly, i don`t have any experience with B series mainboard. All what we tried is C series only (and partially D series too).
So i`m not sure i can locate your eeprom from the photo even if resolution is enough. If you have nothing to loose, you can chec the closest to CPU 8 pin chips and use info on wiki. If you get success, please tell us and show which chip is eeprom. But if not, then i would reccomend you to buy new mainboard and not B550 one, but B650! It is cross-compatible and you get your TV upgraded. Think about :)

Hello,
I had the same problem you, I tried to change te mode from B550 to B650 and my TV was Black and I couldn't do anything with it.I found this article : http://www.avforums.com/forums/lcd-led- ... 2-a-7.html from jeroenb and it was a succes :).
Hope it isn't to late for your TV.
