Dear Sir/madam,

This sounds like convergence trouble.Try doing a autoconvergence in your customer menu.If this doesn't correct the problem,call customer service.Is it under warranty?If not will recommend a authorized service center in your area.If the warranty recently expired,you could possibly get company to pay for a "one time service authorization"for your satisfaction.

thanks
good luck

    If your model has balance button, try using it.
    Try also unplugging TV for one hour or so, if you did not do it before, this will reset TV eeproms in case it is a chip problem.
    More likely you will need to adjust convergence/voltage and ray gun projection adjustment, this procedure will require opening the tv and accessing to adjustment controls, and must be performed by a technician.
    Here is an example of RGB / voltage / convergence adjustement performed on a different model. The whole procedure for your model is illustrated in the Service manual.
    DIY on TVs involve hazards and the risk of causing more damage to your TV, unless you can fix it with the simple procedure listed at start, my suggestion is calling a technician for repair.

Pink and green diagonal lines rollng across the screen??? panasonic 42" Plasma . Only purchased about 3 years ago - but been used very rarely.


Have you tried lifting the ground on the TV? That set has a grounded (3-prong) plug and sometimes sccrolling lines can be caused by a ground loop in your power lines.Are the green and purple lines very short, like just a few rows of pixels tall, or multiple inches, like 3 - 8 tall?

Black vertical line 2" wide with a very thin green line


Hi,
The black vertical line is caused by a leaking capacitor, Check and replace poped capacitor with a new won and it will work fine again. No worries.
Thanks for using fixya.

POP and noothiing


yes it can still be fixed! the pop sound you've heard maybe came from a blown capacitor in the vertical deflection circuits. this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
