Re: Mitsubishi WS-65611 dead

There's no board which your push button power button connects to? I may be mistaken but I'm pretty sure this is still considered a microswitch or a momentary contactor. Whatever you want to call it. I've had these go out on laptops and computers as well. You should be able to put your multimeter on the back solder connections (making sure it's unplugged of course) and depress the power button and make sre the circuit is completed. Like I said I'm not a tv guy but it was just a simple suggestion and I've found lots of people don't try the simple thing...

Re: Mitsubishi WS-65611 dead

I'm not a tv guy but have you tested to make sure your switch is actually good? If the tv is good I would test switch at back of board then move on to jump switch connection at tv board itself.

As soon as I get off work I'll pull the main board and take good photos of front and back. Thanks again Bill for all your help so far.

Re: Sanyo DP50747 50" / LG PDP50x4 T000 Panel Tv won't show video

Ok, plugged in this evening and was back to the GOOD setting D3-D4 ON D2 & D5 OFF. I noticed the ribbon cable attaching the Ysus to the logic boar appears to have one connector that is somewhat rubbed on the end of the ribbon. I think this may be part of my issue. Back to origional Ysus board and lights are at good status. No really singing like it was just a simple little purr almost. Not as loud as the fan in my monitor.

Now, after disconnecting the LVSD cable I shorted pins 1-2 win an insulated...

Attached is the panel service manual. I will attach photos as soon as I can shoot them and get them off the camera....

BW Figured out the LVDS is the cable that goes from the board with the inputs and tv tuner on it to the Logic board, right?

Re: Sanyo DP50747 50" / LG PDP50x4 T000 Panel Tv won't show video

Plugged tv back up to try and do the short thing and now status leds are as follows no matter which oard is installed:
D2 - off D3 - on D4 - off D5 - on

This is the reply I got from Sanyo:
There is a panel self test for this panel. It eliminates the Main Bd. during the test. Unplug the LVDS cable from the Main to the Control Bd. behind the Main. Short the two pins in the attached jpg file. If the self test works OK, the panel will have several internally generated patterns on the screen.

D2 & D5 = off
D3 & D4 = on
for a working TV


Just wondering which is the LVDS cable is this the flat ribbon...

This is my first post and I'm not a tv repair professional so please go easy on me if I've done soemthing obviously wrong and this is an easy fix but I have searched through the posts pretty hard and did not find my exact problem.

What I have is a 50" Plasma by Sanyo/ Lg parts. Lg Panel is PDP50x4T000 Sanyo Model is DP50747.

It is powering on and the screen is lighting to a glow but no picture and no menus. There are also a very few pixels that sparkle every few seconds or so. I took this tv to a local shop and they may not know what they are doing but here's...
