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: 1" black vertical line in center of screen. Sony Plasma.

NOT DEFECTIVE!!!
There are 4 or 5 ribbon cables on the bottom or on one side, they control part of the plasma screen. Check the ribbon cable2_bing.gifnear the black lines. Unplug the ribbon cable and look for black chipson the underside of it, I think they say 100 on them, you need toresolder both ends on each chip. Should fix the black line issue.

Mines a LG RZ42PX11 it intermittently gets a black vertical line down the middle of the screen.


Hi I have a LG RZ42px11 there are 6 vertical thick black lines running down the middle off the screen, when cold the TV seems OK but if it has been on for around 10mins or on standby the lines stay on screen.

Thanks.

Vertical black lines. But they are not solid. lg plasma 42pc3dv


This could be a poor connection with the LVDS cable which runs from the main video processing board to the screen, or a fault within the video processor on the main board. Worst case scenario is it could be a fault with the screen itself.

Multi coloured vertical stripes on plasma screen


With half of the screen working, and with a Plasma tv. I will look at the driver board as being bad. Take the back cover off, the driver pcb will be at the top or bottom of the set. They are only about 2 inches tall and will cover most of the lenth of the set (2 boards that run end to end). The board that is on the side of the tv that is bad is the bad board. Replace that board or have a tech replace it.
