SOURCE: 40 inch lcd blue line vertical

The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!

You have a burn in problem from watching widescreen movies.If you have access to a signal generator or tv setup disc run a perfectly white screen on the plasma for about 30 min.This should help even out the pixels on the display.

Contact Samsung and demand a replacement television. With my situation, they had me take it to a repair shop and get an estimate. I was originally going to get nothing, then after several correspondence, only the parts for free since it was out of warranty (not too far out of warranty) and pay for labor. They decided it would be too expensive and difficult to find the part. They ended up letting me pay 350 for the same tv but 2 years newer. It is definitely worth the price since the labor alone would cost that.

Hope this helps!

All I can tell you is that you maybe have left your T.V. on a channel that didn't move for so long, or maybe someone else did and it burnt the screen. Plasma's run off of plasma gas to create the great picture and they collect on the screen and stick. What you need to do is go to your menu and look for "screen burn protection" and put it on white and let it sit for 20 minutes. All of one color such as white doesn't harm your T.V. The only way anything burns is like a bright white line in front of a black background.

My 50 inch vizio plasma tv has a 7 inch blue line down the center of the screen and there are a couple white half iunch lines in the center of that. if i hit the input button it will disappear and then...


Since the lines are vertical, the image is lost sideways and the corruption changes with the image then clearly this is a sign of Y-Sus failure, not the Z-Sus or the buffer boards.
An logic or input board failure would affect the entire screen, not just a part of it and a failure in one of the buffer boards would affect strictly defined lines of pixels and the defect would be constantly there all the time.
Since you haven't told us the exact model i can't point you to a replacement board.

I have an LG Plasma Model#DT42PY10X. IT HAS A RED LINE RUNNING DOWN THE RIGHT HAND SIDE AND i WOULD LIKE TO KNOW HOW TO FIX THIS PROBLEM. THANKYOU


Hi:
If the line is less then 2 inches wide this us a good indication of a bad PDP panel (Screen) usually very thin lines indicates a failure in the screen itselg, altho you might try replacing the upper and lower buffer boards to ensure its not the screen. You might want to take off the back and try reseating all connectors leading to the buffers and the Digital board. But in my experience thin lines less then 2 inches usually results in a bad PDP.

We have lost a two inch wide black section on the right side of the plasma panel, any ideas


Most likely the lower buffer board " E " needs to be replaced. Right now I'm working on repairing a 42" Samsung plasma HP-R4272. The Service manual for that TV says for trouble shooting for that problem is the lower buffer board " E ".
Best to find the correct Service Manual for your TV over the internet to get the correct part number for replacement. The Service Manual should be less than $20.

Vertical black line, left of center screen, 3 inches wide appears when plasma tv is cut on.


You either have a bad buffer board or a plug that has gone bad. Being that the line is that wide I would almost bet that the board is bad. Have a repair shop check it out. Thanks

JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic


Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:


JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

Phillips 42 inch Plasma -Screen Issues!!!


intermittent loss of picture on either bottom or top half of screen is specific to y buffer boards located on left side of screen going from top to bottom when looking at back of tv. the y lower buffer would be the board to replace to resolve the loss of bottom half of picture. if the top half also is going out intermittently could tied to upper buffer as well but just a note the y main board to right of these buffers drives those two boards so in some cases could also be part of the problem. if only bottom half is affected i would recommend replacing lower buffer only

Vertical line on screen


It sounds like you have a bad cable coming off of your Plasma Screen that goes into one of the buffer boards or a bad buffer board (Hopefully the latter which is easily replaced but most likely not!) I have run into the same problem and there is an IC made into the cable that goes out and would be very difficult to repair if it is even possible.
