LG 42" plasma with mirrored lines on the screen


Contact LG to see if known issue with the model number--in general this can be a communication problem between main board and panel, can also be a bad board that drives the panel (usually on one side of screen) and can even be the display panel (entire front screen unit) which is fatal from a cost point of view.

Someone has to open and inspect and then if finds something amiss order and replace boards to see if that cures the problem or not.

A black line down the middle of the TV can be a few things. You plasma panel might be bad your buffer on that location of the screen might be bad or your logic board might be bad. Teh only way to find out is by replacing the parts , You can get parts at www.interliquidparts.com

Hi i have a lg 50pg3000 plasma the screen has 2 thick black lines down the righthand side thay some time go bum most of the time stay unless i give the tv a bit of a twist then the lines go for about 1hr


Hi, you can try tightening the ribbon cables that run from the screen to the buffer board , only tighten the one near the line area. if this does not help you probably need a new buffer board or panel (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.

Line down middle of the screen-resolution is different on sides


Computer parts can sit in warehouses and be on trucks for a long period of time. Unfortunately that means things get banged around. Sometimes they don't even work when they come out of the factory. I suggest exchanging the monitor for another one. It could also be your video card. Easiest way is to exchange it and it's free to exchange.

Black line down screen


hello, your tv has either the lower or the upper buffer defective, worst case scenario is the screen but only a tech with the skills can determine wich one is bad.
good luck

Black line


I just had this problem with my Samsung 50' DLP HLR5067WX/XAA. Fortunatly it was still under warranty with Best Buy, so they fixed it for me. They had to order a brand new light engine. (or where the mirrors are, if i'm not using the right terminalogy) He said the problem is with one of the mirrors that has slipped (or slipping because overtime the black line will get thicker and thicker). I hope i'm saying it right, but it was with a tiny mirror that was slipping. Hope it's under warranty. I've also had 1x component plug burn out on me, my HDMI port went to ****, and he's gotta come back out because when he made the repair, the picture was reflecting too high up and to the left. (MLB 2k7 for xbox 360 - scores on top of screen are about 1/4th cut off). He said is next trip back to my house would result in me getting a new TV, so can't wait for his arrival! good luck with your tv

I need to replace a broken screen on my sony kf 50we610


Hi drdoolittle,

Some screens have labels, so place them so the labels are upright and tward the front of the TV.

The outside screen is the lenticular screen. The black vertical lined side is outside. The fresnel screen has very fine circular lines in it. You can find them by feeling them. This goes against the lenticular back side of the screen. the fesnel has a flat side that is the back. It will be tward the mirror. If the mirror has two shiny sides, then it should be placed with the mirror side out. You can tell this by placing your finger tip on the mirror. If the finger nail meets a fingernail, then this is the mirrored side. Install this side tward the front.

Try to keep dust from between the screens. Check by looking through the screens before you put the in the frame. Then check them again after you put them in the frame.

Wear latex gloves to keep finger prints away.

Clean back of screen assembly and install the screen on the TV.

You can now watch the TV.

Cheers, CrazyLee
