If you can claim warranty just do it it is safest.
Shorting pins is always a last resource if nothing else works.
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...
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
