How much is a fifty two inch plasma tv screen replacement

SOURCE: Red noise or flicker on bottom half a plasma screen

The old saying that a pictures is worth a thousand words could have been looking at this one... If the lower screen had been streaked in B&W or bands ran completely through the picture Old Drummer I would suspect the logic board also but that's lower y-board failure.

Versed, you have to open the back panel (cover) to access the lamp. replacing is easy as soon as you can see it. loosen the mounting bolt and pull to unplug the lamp from the SMPS Lamp power supply. Thats it.

open the back of the set and inspect the power supply board -- there should be two fuses on the board- they cost around 2 dollars at radio shack -- check all connections for wear or damage -- there are two boards in most televisions -- a power supply board and a audio / digital board -- one is probably board

I wanted to share my solution to this problem. Not only is it an easy fix (aside from taking the tv apart) but it also explains some of the strange methods I've read that have worked, such as taking out padding from behind the boards or putting a magazine under one side and even tapping on the tv for a temporary fix.

Granted its only been a few days of it working but I tell you this....It's not done the half black screen once! And trust me when I say it was doing it constantly.

Ok so first off the problem definitely lies in the upper/lower buffer boards. On the model mentioned by the OP (same model I have) it's located on the same side as the power button (right side when you are looking at the tv).

Ok so you've got the tv openned face down on a non static surface. Btw I was shocked at how many youtube videos I found of ppl working on their tvs while its laid flat on their sofas!

When you are looking into it you will see on one side there are two vertical boards hooked up to another board more towards the center. These two boards are your upper and lower boards that provide the upper and lower picture. The problem I was having was in the lower section of the tv going black so obviously that corresponded to the lower board. (They are labelled upper and lower if you look closely)
So here is what I did:

I noticed the lower board was not sitting flush so I unscrewed the one screw on the bottom and noticed how much of a gap was in the screw hole. The problem was it was screwed down in such a way that one of the connections going to the main board was not making it's proper connection. So I just gave it a little push towards the center, held it, and screwed it back down.

That's it! It's fixed now. No need for replacing anything. Just poorly drilled holes and a few things not lining up correctly!

So hopefully anyone else that's having this same problem might have some luck in using this fix. Good Luck!
