You have bad solder grounds in your TV. There will also be some bad capacitors. Look for capacitors in the range of 160 volts to 250 volts at 1Mf to 2.2, 3.3, or 4.7Mfs that are bad now. Another common capacitor that goes down are the 25 volt or 35 volt 100Mf ones. The next area would be your vertical IC , it will need resoldered. This is true any most cases of any brand. The capacitors next to the vertical IC will need checked and replaced. A bad cap here will heat the vertical IC and separate the pins from the board. Last and be sure to do this. Check the small board connected to the picture tube. By now this board (CRT) will have many bad grounds. Heat is the enemy of any television. Hope I could clue you in to a repair. Thanks for asking and show a few hands of support!

Turn on, comes green led then goes off after few minutes.


Does the whole TV go off or just the lamp? If it's just the lamp, the ballast board which is directly connected by wires to the bulb is going bad. If the whole TV goes off, then something is dragging the power supply down or the power supply board itself can be bad.

My Panasonic LED TV picture goes away after a few minutes


Could be a bad connection that disconnects when heat in the system causes it to expand. Take to a pro or call manufacturer, they might have a recall or free repair available.

When heats up, the supply voltage from the main power supply board goes less. Check all the soldering to this board for any loose solder terminals. Resolder all the suspected solder terminals by applying a little more solder. If it do not help you, replace the board as card basis.

Tv goes blank after a few minutes. Turn tv off and back on and it will come back on for a few minutes and go blank again


You are having trouble with a thermal protection switch in the TV. The power supply will have to be replaced. It is also possible that your lamp (tubes behind the LCD panel) are going bad and drawing too much current and causing the power supply to protect itself.

TV Turns off and on


How long since the last time the bulb was replaced? It sounds like the bulb is overheating and triggering a safety shutdown.

It's probably in need of nothing more than a good cleaning (open it up, clean off the boards with a can of air) and *may* be time to replace the bulb.
