Picked up this set today.
- Plugged it in, got a standard blue steady standby light on front
- Powered it on, got one solid click, flashing light, happy Samsung beeps, standby light goes out, NO PICTURE (TV thinks it is on)
- Smelled faint burning, powered it off, got standard Samsung power off beeps
- Opened it up and found on of the chips on the y-upper has a burned pinhole (tested to verify and it got extremely hot almost instantly)
Since then I have (all the noises I mention are very faint, wouldn't hear with rear of tv on)...
- Powered it on with the y-up disconnected, no picture, slight humming and cycling noise coming from y-main
- Powered it on with y-lower disconnected, same result
- Powered it on with y-main disconnected, still slight humming from main power board but no more cycling noise, no picture
- Powered it on with secondary power board disconnected, no more humming, no picture
Tested all voltages, all are spot on to within ~3%.
Should I be getting a picture at all (diagnostic or just backlight)?
Where should I go from here to tell if I have just a bad y-upper, or a bad Y set of boards, or if even more than the obvious board is bad?
Thanks for any help.
