SamyGO

Maybe turn on tv and keep button pressed for 20 secs
If you can claim warranty just do it it is safest.
Shorting pins is always a last resource if nothing else works.

Yes, you can feel some burn smell after procedure and lost warranty. Seems you should beter call technician.

Pictures are poor quality and i don`t see here any fonts on microchips.
Please, use search function (here) might you find similar mainboard with marked pins and howto.

Or you can call technician, because this game is dangerous for TV`s life...

I think we need collect all possible m/b and marked chips to one database... Might in future...
Congratulations

Great job
Maybe we need to create matrix on wiki with model, chip, picture of mainboard, latest firmware possible for samygo, direct link to hack page, preffered jack tool, etc.
This would give a nice overview for newbey and vetterans
Just my 2cts
