My big screen mitsubishi PTV (VS-5059) occasionally flashes a red Horizontal bar across the screen. It eventually comes back to a regular picture. My guess was a problem in deflection. would this be an accurate guess or am i just wrong?
If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages.
This should not be an expensive job at most repair shops. Could be
something as simple as cracked, cold, defective solder joints around and near the vertical output chip, could be a faulty chip and other components in and around the vertical deflection circuitry, or a faulty vertical drive signal from the jungle circuits, or worst case a faulty deflection yoke. Take your television to a shop right away for a proper and safe repair. Do not keep the television looking at the red horizontal line....
you can easily damage or burn the CRT phosphors.

I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.
Good Day, marvy21; try theses ideas, they will fix the TV # 3 is most common, you might start there.
1). VERTICAL ROLLING, VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE, ALSO MAY HAVE HORIZONTAL PULLING OR TEARING. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2). CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.2). CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.
3). CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB. Good Luck, big IRISH.
I turned the set on and everything was fine, then the screen went black and mullti-colored horizontal (arched) lines were flashing across the screen. The next day I turned the set on and everything was fine for about 5 minutes then the problem reoccures again. Haven't looked for solutions till now.
Here's something that might also be useful. After you turn on
the set, and get the regular red blinky lights, hold down the Device
and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
