I tried to update LE40A556P1FXXU firmware via USB and there was an AC power disruption.
TV power led functions as normal but screen remains dead and I cannot now press SOURCE on TV and POWER on remote to try reflashing.
Would shorting EEPROM help start TV again? If so can you suggest IC to work on?
The cost of a replacement board means the TV isn't cost effective to repair as it suffers from terrible IR anyway.
Any help/advice welcome.
It's a shame firmware chip cannot easily be replaced, not to worry I have sourced a cheap replacement board so should at least get it working again.
I will start a new post with another question.
