Question about JVC PD-42V31 42 in. Plasma Television

1 Answer

Vertical muliticolor lines

I read the explanation for the VCR hookup causing the lines. However, my JVC 42inch plasma has re-occuring vertical lines through every outlet of viewing...(ie DVD, regular tv, gaming station). This problem is on and off, and this just started occurring a few days ago, my tv is only about 2 years old.

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: Vertical Black Line

HI,
First thing to do is the reset and the whacking test. I give this a 50/50 chance of clearing it up.

ONE: Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.

TWO: The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.

If these two procedures do nothing then:

The manual always knows the best.Go through the manual carefully and u will find the solution to ur problem..

Goodluck and Kind Regards
Please Don't forget to rate me as fixya..

Green vertical line on videocon 42inch plasma tv


Hello Depending how wide the line is their could be two possible causes.
I have two questions for you.
1. How wide is the line.
2. Does it run from top of screen to bottom of screen?
If the line is thin a single strait line then it is possible the PDP has gone Bad (Panel). (Screen). The screen will to be replaced.
If the line is at least 2 or more inches wide then its a buffer board which can be replaced. LG calls this board Hand insert Boards or display driver boards..
