SOURCE: Static lines one screen

as the top is ok and the bottom has this issue.
It looks like the circuit board has a bad connection to your screen.
it is not repairable by you and not an adjustment.
you need to have it repaired.
don't you miss the old wack on the side fix?

SOURCE: 42" LG RZ42PX11 Plasma - rainbow lines on whole screen but sound

hi there.its likely that the lower y-drive panel has died.this is a very common problem with this model.the easy way is to remove the panel from the set completely,power it up and you should be greeted with the top half of the picture.this means ic failure,usually the bottom one for some odd reason.not replaceable unless you have the gear,these ics are available from dalbani(nikkai)for those interested.be extra careful with the four ribbon cables when removing/refitting.damage to these writes off the display panel.hope this helps somewhat,regards,steve.

SOURCE: Vertical white line down centre of Soniq PT42SH plasma TV.

One of your "X" buffer boards is defective. In Panasonic plasma tv's they are located at the bootom of the set and connect directly to the plasma diplay panel via a thin ribbon cable. The board you want to replace will be directly in line with the discolored vertival line in the picture. The part number is on the circuit board and usualy starts with "tnp..." or "txp..."

Hi.. Mine is a sansui tv and I bought it 3 years back. Now it is showing a horizontal line on the screen. Sound is fine but I can't see the picture, I just see one white horizontal line on tv...

The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.

Tv goes to straight line in center of picture then

It happens when Vertical deflection stops as Vertical Out IC becomes hot or does not get vertical signal.
Please check electrolytic capacitors and dry solder joints in vertical out section in TV.

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

lcd or plasma.
are the lines solid or blurred. do they have sharp edges.
You may have a memory problem with the display which can only be repaired by factory trained technicians, or a brave soul willing to find parts on ebay.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

Top of the screen Picture Problem

sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem. good luck.

32 inch panasonic tv

Your problem is in the vertical deflection circuit. If you know how to solder it may just be a cold solder connection, but if you try to solder it and it still does not work, you may have a bad Vertical output IC. This set has really no user replaceable parts unless you have some no how on serviceing solid state printed circuit boards. If you dont , my advise would to seek out a repair depot and have them fix this set for you. It should not run more then 150 bucks or so. Good Luck Ps please do not forget to rate this thread.
