im working on my uncles sony tv, and he had the 7 blink code going on. so i replaced both ICs on the D-board and now i am getting 4 blinks?! i can't seem to find what this is. everytime i search i come across the 6 or 7 blink code. i know this request might be way out of date but is there anyone that can still help me out on this? please.
