WOW expensive set! Sorry to inform you that you do not replace separate pixels in this set. It comes as a whole assy. There are 4 of them and last time I saw one or the price it was around 4 to 5 grand I think. Or the driver board is bad. I would disconnect one panel and connect it to one of the good panels to see if it is the panel or the driver board. That would be one heck of an expensive mistake.

Black line half way down the center of the screen,about 1.5 inche


There's a 'data control' and/or 'address' problem that's developed. Pixels depend on voltage, control, and data coming too their designated address.

A digital circuit feature called a 'DATA_ADDRESS_ BUS" are responsible for 3 criteria: Delivering voltage, control, and data to each pixel in less than a second.

1) If voltage fails the pixels don't light up. They appear black in color (their 'off 'state)....numerous pixels that don't light up look like a black line. But their actually individual pixels with no voltage.

2) If control fails then all pixels are white in color (their 'on' state). Without control the pixels can't adjust properly to high or low 'state', meaning brightness and dimness. This looks like a white line vertically on the screen.

3) If data fails then the pixels can't adjust to the proper color at the proper time.
This appears as a line that changes color out of sync with the entire picture.


Have a technician look at the pixel address registry circuits. As well as control and linear circuits....the problem is somewhere in there!

Pixels aren't refreshing correctly in upper right hand side of screen


You might have a Service Co. come out and look at it. It sounds like the Z module is not doing it's job of erasing all prior images after a scene change. Some models there are adjustments for that internally. ( only for a tech ) Start a paper trail now.

I have a problem in 84" orion plasma tv. in which one qudrand picture is comming like vertical lines


84" tv wow. You must be rich! Modern televisions are controlled in sections. If you are having trouble with just one quadrant on your tv, then the video driver board responsible for that spot has gone out. I would expect you will have to pay a tech to replace the board for you. That should cost at least 500-1000 minimum I would guess.

Red pixels on the Srceen


Dead or stuck pixels are not uncommon in LCD displays, and the less you pay, the more likely it is to happen (as a general rule) Most manufacturers will a dead pixel warranty, ranging from 7 days to lifetime.

Read your warranty carefully, and speak to the place where you bought your display.

I hope that helps, if you have any further problems, please add them ass comments to this question. If I have been able to answer your question (or not) please click on one of the ratings buttons to let everyone know how I did.
