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....

Re: Sanyo DP50747-01 no video or sound??

Oops typo 3300mf...! ...

PlanBill,

I'm attaching several shoots of the rear as you requested. The P/S is missing from these pictures as I have it on the work bench, so a separate snapshoot is included.

The YSUS is listed as LGE PN:EAX34151601 Rev C and the ZSUS is listed as LGE PN:EAX34151801 Rev B.

I circled the items replaced on the P/S, the blue circles shows the MOSFET replace all are the same , the white circles shows the replace set of caps, and the red circle shows the CN206 with Vs and Va stencils.

I'm posting this new thread hoping to see the light after a dark tunnel..!

This Sanyo TV had a problem with shutting off after a few min. I did a visual inspection on the main P/S and found 9 caps (680mf 10V) bad (the top popped). These were replaced and fixed the original symptoms of shutting the set after a few min.

We connected the set to the cable box and everything looked fine, except the video started to blink only on HD channels, regular non-HD worked ok. After a few days the video was gone and same with the audio.

Back on the bench, a visual...
