Take the back off the unit. There are 2 20 pin cables that go to a small board that sits on the right side (viewed from the rear) spray the back of the plugs with contact cleaner and wiggle these cables where they plug into the small board.

If they are stationary vertical lines in picture and consistently appear after warmng up most likely would be a display issue. displays have control boards attached to them that would sometimes cause intermittent lines to come and go but if when these lines appear, they do not go away without powering off and leaving off for awhile and if no video can be seen behind lines the lcd panel would be where the failure is and would have to be replaced to resolve issue

I have a 52 inch Samsung TV, on the screen have solid, color vertical lines on the right, about 1/8 wide, on the same time the half of screen blink on the right too.


not knowing the model... i will try to help with this common samsung issue, if i can. / unplug the tv, and wait a few minutes to avoid shocks. / remove back panel. you will see several ribbon connectors, (about an 1" to 1 1/2" wide) usually near the bottom. / carefully remove the ribbon (ONE AT A TIME) and clean the contacts GENTLY with a pencil eraser. (DO NOT use chemicals) / reinsert the ribbons and try the tv. // vertical stripes are almost always the result of poor contact between ribbon and socket. / NOTE!. you can do a quick test before opening the set by [carefully!!!!] twisting the screen and watch to see if the vertical stripes change or disappear. / if the stripes change, bet on it being the ribbon contact problem.//// hope this helps, it has worked on a number of TVs.------Jay

5 inch wide blue vertical stripe on lcd


It can be but rarely the main board, most of these sets have either one or two boards that drive the image on the screen, different names like T-con or Y out etc. the right side board could be the problem or a bad connector or ribbon cable for that side of the screen unit.

Several possible cures and none are a snap to find in most cases.

If, when removing all souces, it still shows the fault, I would have it exchanged as it is clearly a Friday afternoon one. I suspect it is caused by a cableing problem. Disconnect and reconnect the signal cables one by one and the fault may go.

Coloured lines on screen


Make sure first that the picture is centered by using the remote control to move the picture vertically and horizontally. Use the round pad towards the center of the remote and push the button according to which direction you want the frame to move.

42" Panasonic Plasma - Vertical red stripe 6" from left side


We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?

SCREEN PROBLEM WITH HITACHI 42DP8600


It is dry solder joints inside the tv. If you are going to do it yourself try these places for a fix: vertical scan board, focus board, line output board, chroma board. If you are not able to do this yourself then find a competant technician. Hope this helps.

Red lines on right hand side of the screen now no picture on right hand side!


I'm not an expert, but I have determined that the vertical bars that are often red, sometimes blue ... and sometimes both ... are related to a bad control board. I've also read that a common fix is to buy a repair kit with includes the ysus, zsus and control boards ... all replaced together. My experience was that after a month or two with the 1.5" wide stripes, that you eventually loose the entire picture and have sound only. MIne comes back, but won't stay working for very long and the stripes are always there (buy used to fade and flicker sometimes). I'm planning on replacing the control board.

Dark lines on the sscreen


This indicates that there are bad connections in the cabling going to the display panel. Usually there are tiny connections along the top of the panel that rely upon pressure to hold the contact material to the panel contact and if the assembly is not right, gaps form in the picture like you describe. Sometimes just sqeezing on the units cabinet in the area of the gaps is enough to affect the problem. May need to go inside and work on the contact assembly.
