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: Screen Changes and Comupter freezes

It may be possible that the power supply, display and or logicbpard may be having issues. Apple recommends resetting the pram and nvram. If issue persists reset SMU. YOur machine is 6 months outside of the original warranty, but if you purchased the 3 year extension plan, you may want to take action on it.

SOURCE: Vertical portion pixelats then forms

Note
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.

SOURCE: No picture, Horizontal line center of screen

you either have a bad solder joint at the yoke plug. Thats the large group of wires coming off the yoke on the picture tube neck, Resolder where that plugs enters the chassis the pins may have a crack in the solder, The other item to check is the solder around the horizontal output which is mounted on the heat sink near the flyback transformer. That Transistor could be open as well and if so it will need replacing. Try the solder first however as that seems most likely.

There's a blank bar that runs horizontal in the middle of my TI-84 plus that's about 16 pixels wide(high?). It's the same color as when the device is turned off. I've tried a memory reset and no results....


SPLIT SCREEN.

It sounds as if you might have split screen mode on. I've got a TI-83 as well as a TI-89 Titanium, both offer a split screen mode. The latter allows for choosing which applications are displayed on each half screen. I am presuming that you may have accidentally put your TI-84 in this mode.

So, if it is a split screen deal then all you have to do is go to the mode screen, find the option for switching from split screen to full screen, and switch it back to full.

I hope that helps. Give us your results!

Adios

Why have i only got half a screen


The calculator can be split in two. This is done by selecting certain MODE options as shown on the line that starts with FULL
c8aef96.jpg
In the Full option the screen is complete (regular screen configuration)
If you highlight HORIZ and press ENTER the screen will be split HORIZontally as
7ebfe39.jpge637e8e.jpg
The upper part is for any graph and the lower part for the main calculator screen
Similarly, if you highlight G-T and press Enter, the left part of the screen displays the Graph screen and the right part the Table screen.

These are the normal instance where the screen of a Ti8*Plus is split in two.
Do you recognize any of these?. If you do just select Option Full in MODE screen to restore the full screen. If you do not, then I have no idea why you only have half a screen.
