Phillips 50 inch Plasma

Maybe it's time 4 a new t.v. Do you leave t.v. on a lot or play a lot games. Turn off your t.v. when not using. Is t.v. old, get a new new one. You will be you did. The newer sets have HD which make for better viewing. I suggest an LED and not a Plasma.

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further solution updates will be on my Facebook page.

Filter capacitors (more than 1) in the main power supply

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

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.

Hello
You will have to a tec. for this one as you have lost half of your vertical sweep.
Sorry

This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.

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.

This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.

It's definitely possible. I'd have it checked by a repair center for something like this.
