Hi all - have something that I havent read about on this site.
Have this LG thast has no video, bad Y-upper buffer (at least).
However, when turned on - the green light on the Logic board (EBR77186601) never illuminates, no blinking either. I know the light works as when I probe it in diode mode it come on.
Would a bad Y buffer and/or Ysus keep prevent the Logic board from coming up? This even happens when I disconnect the logic board to try and jumper EXT_AUTO_GEN (also no test patterns) - never does the light come on.
Where to begin?
