Inference lines across screen on upper channels

Purchased a 50 inch plasma and a dozen or so upper channels had bands of interference lines across the screen. The store gave us a replacement but some of the channels (not as many) still have the interference lines across the screen. Should we seek another replacement? Is this going to become a bigger problem?

The problem is actually not likely to be the set. The symptoms you are seeing are usually caused by a bad ground connection somewhere in the cable run. Check the connectors at both ends of the cable to be sure that they are secure. There is an open ground somewhere in the signal path. If you have cable or satellite, it could be outside the house as well.

Hi have a samsung 42 inch plasma, all of a sudden it has a band 20cm wide of dotted lines going across the whole screen, some channels or when playstation in use the band gets wider, does not seem to...


if the band is horizontal your tv has bad y-buffer board. Usually there are 2 buffer boards- top and bottom. if the problem is in the top half of the screen replace the top board, otherwise replace bottom board.
but better to replace both a the same time.

if the tv has a vertical lines from top to bottom it may have bad plasma panel and can be considered as not economical to repair.

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.

My 50" Plasma has developed a band across the middle of the TV


All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If you don't have the reciept then call 1-800-SAMSUNG.

Picture Problems On 50 Inch Philips Plasma


You plasma still under manufacturers warranty. Most electronic devices have one year warranty.
The failure in your TV can only be corrected by repairing it.
I would suggest to call philips and ask them to find you an authorized repair center near you to get your TV fix under their warranty.

Nec plasmasync 50MP2


Lol, I'm not a Guru but I am a Wiz, so I can help. Usually, those lines you see, are from the burning of a channel. It's when the plasma gases inside of the screen stick to the screen and don't come off, it's permanent. Unless your T.V. type has on the menu a Screen Burn Protection like a 50 inch Samsung I have. The only reason it burns is because bright white lines in front of a dark background. Usually HD channels have small icons so they don't stick in the screen, so unless it's under warranty, you can take it back, but if not, then sorry. You can't do anything with no warranty or receipt.
