Sanyo DP50747-01 no video or sound Part II??
Part I https://www.badcaps.net/forum/showth...=sanyo+dp50747
OK folks,
I'm re-opening my thread once again after further troubleshooting.
So far I had the P/S repair and all seems to be ok, however one note on the voltages from my previous post.
The Va and Vs (57V and 190V) are now present if the P/S connector P800 (AC-O, RL-ON, 5V sb, DET, Vs-on, 5V-D and GND) which goes to the Main Board @ K6P is removed. If the connector is in place after powering the set the Vs and Va drop down to about 1.5V.
In reading other threads on this model the indication on the Ctrl board LEDs for a working set should be D2-D5=off D3-D4=on. However my Ctrl board has D2=off and D3-D5=on.
Logic dictates there could be a problem with the Main board may be shorting/disabling the Vs-on pin back to the P/S, but with D5=on it could well be the Ctrl board too?
What fault would a D5=on represent?
Any suggestions?
