Plasma options periodically flash on the screen and I don't know how to stop it


Look for any jammed buttons on the remote or on control panel. Remove batteries from remote and retry.

Lg 50pc3d screen and z50pj240 could fit viseversa?


No, they have completely different displays - one is made by LG and the other by Samsung.

You can't mix those two.

Sorry, don't kill the messenger :-)

I have Lg 50pc3d-ud and it has very dark spots on the tv that moves around. The screen is also very dark no matter the settings. The dark spots aren't always there, they go away sometimes but if...


This problems ur tv are having only can be two causes 1) The Y-Sustance main tuner logic board or 2)The tv Plasma screen panel itself it is slowly leaking radiaton and dying,if it is the tv plasma screen panel itself it is dying than the tv not worth repairing because by replacing the plasma screen panel itself will cost the same as a new tv itself.The Y-Sustance board-that the tuner main logic board that take in the tv incomming broadcasting signal cable.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish Y-Sustance main tuner logic board for replacement.This tv problems are 50/50 between the Y-Sustance main tuner logic board or the very exspensive plasma screen panel itself.

Large dark shadows on display,but the menu can be seen faintly,and no control over brightness but overall brightness low.The electronics is functioning o.k, but the dark shadows block out all images...


Sounds like a Z-SUS board. This board "erases" the picture between frames and prepares the screen for the next frame. If it goes out, your picture will be very, very dark. As for the reason... It's electronics, they just break. If you want to attempt the repair yourself, you will need to post the full service model number. ex: 50PC3D-UE.SUSLLJR Otherwise, we can't get you the correct part number for the Z-SUS. I hope this was helpful.

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).
