a customer has sent in this tv, now i kow there are alot of problems with these models - not coming out of standby.
on testing - the red standby light is on, but doesnt respond to remote or side buttons, i know a bad connection on the main hdmi board (ic420) can cause these symptoms.
i have 2 other main boards, which i thought was in fully working order, on testing these - i came across the same problem, however if i unplug the set at the mains a few times, it will power up and stay on endless.
so my question is - her orignal main board is faulty, my 2 boards are working but is there another problem elsewhere? maybe power supply? would a faulty power supply cause this problem?
thanks in advance.
