Re: LG Plasma Model PDP50R40000 Turns On but no picture

Dumb question - I can't seem to figure out how to disconnect the top y-buffer from the y-sustain. The connections are in the pictures from my last post. Any ideas?

Tom66 mentioned to just disconnect the boards and not the orange ribbon cables so I didn't try just disconnecting those from the top y-buffer (although I was inclined to try!)

Re: LG Plasma Model PDP50R40000 Turns On but no picture

Sorry for the delay! I attached pictures of each board and the entire back of the TV. I can provide better quality pics if needed - I didn't realize they got downgraded when I moved them.

I'll try unplugging the top y-buffer board shortly and get back to you on that.
Thanks!...

I will give that a try and provide pictures.

Thanks for the quick response!

Nope, the screen itself looks perfect.

Hi experts,

So I've had this 50" LG plasma for about 3 years now and have never had an issue with it. Yesterday, my wife bumped it (not very hard... really!) on one of the edges and the picture immediately went black with no "popping" noises. When I turn off the TV, the red standby light goes on and when I turn it on, the standby light turns off (which is how it usually functions) but I don't get the LG bootup/splash screen. When I hit the input and channel/volume buttons, the red standby light blinks as usual from the remote input but nothing is shown on the screen....

Hi all,

New member here from Massachusetts, USA. I've been looking over the forums for the last day or so since my LG Plasma picture went black and I'm impressed with the knowledgeable folks here! However, I haven't seemed to be able to track down the exact issue that I'm having.

Info about me: I'm a software developer but not as comfortable in the TV electrical world as I am with computer hardware.

I look forward to joining this community!
