Re: Help needed finding bad board on Sanyo Plasma DP50747 TV
here's the voltages before shutting down. Sometimes a little higher or lower if I do a second reading. When It does shut down, I cannot turn until after 30secs, after the third try I'm locked out. Have to unplug power for a few minutes. Still think it's the power board?
Vs- 38v
Vs- 37v
Vs-32v
Va-6v
Va-4v
chassis number is DP50747-00 from outside cover.

Re: Help needed finding bad board on Sanyo Plasma DP50747 TV
ok.
I put all cables back and disconnected cable from control board to main board. Results are the same. Power board clicks once after turned on than after 2 secs clicks again. Control board has 3 lights lit until second click shuts them off. Power LED on front screen stays lit for about 30 secs after second click. Nothing on plasma screen..
Also tried this same test but with power disconnected from X & Y boards.. Same results except control lights never come on.
thank you for your...

Re: Help needed finding bad board on Sanyo Plasma DP50747 TV
here's what happened when I unplugged all cables from the powerboard except on board AC power.
Once I plug the powercord back in I hear a 1 click, then in 2 seconds I hear another click. This is without pushing the power button. Still cannot measure Vs, Va because it's keeps shutting down. The 2 black relays on the power board are the ones making the clicking. Would a normal working power board click once and stay on? I shouldn't get a second click on the relays.
Now I believe this board is bad because...

Re: Help needed finding bad board on Sanyo Plasma DP50747 TV
I've read somewhere I could disconnect all cables off the power board except the main AC connector then read Va & Vs voltage. If power board still shuts down or voltages don't match on the sticker inside then problem is with this power board.
I was thinking either power board or main board are the problem.
Thanks

Help needed finding bad board on Sanyo Plasma DP50747 TV

here's what I did so far.
I removed 4 fuses and tested them with a volt meter, all good
Didn't see any signs of bad caps or burnt components.
