Jvc gd-v4210pzw screen problems

The display on this unit has a problem. The display is split into two halfs. The split occurs horizontally. Both halves display a complete series of vertical lines that completely cover the screen, however, they do not mirror one another. The colors of the lines change to track the program that is playing. The audio is fine. The unit recently snapped out of it for about about 5 minutes and then returned. I gave it a good slap on the back and the unit corrected itself for a while but has since returned to its problem state. Any suggestions would be greatly appreciated.

SOURCE: Vertical portion pixelats then forms

In some cases, there are minor defects in some parts of the screen. Points that do not light, points with
brightness different from that of the periphery, or points with color different from that of the periphery.
Some pixels will always be on or always off. Please note that this is not a malfunction. So what this says is that it's not the Plasma Cell problem, its more like a bad board inside. You will need more info like schematic and find out which area the bad part is in.

SOURCE: Thin black horizontal lines on JVC PD-42WV74 EDTV

horizontal line is an idication of a bad board known as a x driver board. Their may be a slight possiblitliy it can be a small ribbion cable that runs from the driver board to the plasma panel. Another possiblility it can be a bad panel... but from the symptoms you describe i would first have to look at that driver board. and the sympton that getting worse makes me lean toward a bad ribbion cable.. if that could be reseated....well that the first thing as a technician i would try. Carefull Television generate dangerous voltages.

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.

You need an Analog Board. It is the one in the middle. You can find it on ebay for $50 I think.

My screen has split in half horizontally mirroring the top with the bottom.

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic

Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:

JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

AKAI LCT2662N screen problems -distorted

that sounds like your LCD controller, since the LCD screen is so big, they will "split" the screen into 2 smaller screens, otherwise it would be so outrageously expensive to have one big massive lcd controller. Your lcd controller is most likely a two-in-one card though, meaning that there are 2 controllers on one board. You'll more than likely need a new controller card for your tv.
