Gateway plasma gateway plasma 42 about 3-4 years old has red and black horizontal lines running through the picture. I can turn tv off for a couple of minutes and then turn it back on and the lines are gone but only for a little bit then they are back...

Please tell us what model gateway TV

Gateway 50" plasma tv #7005406 runs only in black and white after power outage. Menu screen still in color.

Normally, it causes by failure of power supply board.

You need to call a technician.The problem lies in the board [internal].

hi....Your tv picture is managed by several boards, the two specific ones are the ysus and the xsus. The Y controlls the horizontal pixelation and the X the verticle, if you are having horizontal problems then its the Ysus thats faulty, on this particular set, the Ysus board has two accompaning buffers that are particularly troublesome. I've had more than one of these sets in the shop recently with the same ailment.Sounds like your buffers are starting to go out. The screen is split horizontally by the two long skinny buffers attatched to the Y main, if the bottom one has one leg in the grave you'll be getting a partially black screen or no picture at all. The colored lines running through the screen are more typical of a failing buffer. Are you interested in taking this set apart and putting a couple hundred into fixing it?  When buffers go they usually take the Y main too. Worse case scenario you're gonna be out about $350 dollars to fix it yourself. Best case, a ribbon is loose on the bottom buffer and with a dismantle you'll be able to connect it again..

thank u rate me!!

THIS IS THE START OF THE PLASMA GAS RUNNING OUT...PLASMA TVS ONLY LAST 4 TO 5 YEARS THE GAS JUST BURNS OUT....LCD TVS LAST ALOT LONGER UP TO 10 YEARS..

Search Google "Screen Burn-In."
Mainly Plasma screens are affected by it.

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.

Are the solid horizontal black lines or colored lines. If colored lines there is a posibility that your Y-main, and upper and lower Y-buffers are bad. If black you have a bad plasma panel.
