Samsung BN42B400P3D PLASMA standby light only.
Little red light front of panel is on but the tv won't turn on. either with remote or pushing front button.
What I've done so far, I replaced the PS board with a known good replacement and NO change. All caps on old board looked good. Ive seen cases where a bad Y-sus can prevent these from turning on. However, in each of those cases unplugging the Y-sus board from the PS will usually result in a change and will allow you to turn on just no picture.
What also baffles me is there is NO usual "relay" click when plugging into the wall outlet. Is it feasible that a bad digital main which the front ON button ties into is preventing her from firing? And I don't imagine the noise filter block to which the plug goes into would be bad?? I guess you cant rule anything out, but ive never seen that?? could be first time for everything I suppose
Hopefully someones played with this model before?
