kv-ex34M87 (huge tv) served for 7 years without trouble.
the only no. i found on pwr etc board is: CMKI-81x
also after resoldering tv becomes live after a very short time compared to as it was before, it takes 1-2 min. after red led
green blinks twice, relay also clicks all times.
set parts are overall apparently cold. and i cant locate the fault exactly.
when alive again pic&sound are crystal clear.
thank you for your kind attention.
Ubai

sounds like a cold solder joint to me. you might try getting a bright light and touch up many of the solder joints. also try poking at the board with a wooden stick, like a chopstick.
