My JVC 35 inch television will be working good then will shut down and just show a thin red line. After a few minutes the tv comes back on. What causes this

Sound like your Y-Sustain board has one foot in the grave. The Y upper buffer and Y lower buffer boards go when the Y Sus Goes too...

Good day..


That problem is usually cause of bad capacitors on the power supply section..

As you stated your TV works fine and after a minute the red light comes on...

That symptoms is cause of bad capacitors..Normally bad capacitors can check visually if the capacitors look like leak/bulged on the top that is the indication of bad one but not all bad capacitors are bulged some are not so in that case you have to used a special meter called capacitance meter..

This is the sample picture of bulged capacitors:

try turning off the auto shut off feature in you set up screens . you can find them through the menu button on your remote. scroll through till you find it and turn it off.

To me, sounds like a picture tube issue. horizontal / vertical controls don't fix it. then its dead.

I had the same problem. i was told by one of these so-called experts @ fixya that my flyback transformer needed to be replaced (the 8 blinks on the standby was the indicator). but i recently replaced it and im having the same problem. sorry. no advice. good luck.

Your tv has a video problem, leak capacitor in video section, near in flyback need to replace it.

It sounds like cold solder joints on the vertical IC chip. Not a major deal. The entire board should be looked over for other joints becoming cold.

you have a bad lamp or balast

47" JVC TV TURN THE POWER ON THERE ARE SOME BLUE LIGHTS THAT COME ON BUT NOT THE TV. THEN AFTER A FEW SECONDS THE BLUE LIGHTS FADE AWAY.

I really dont understand the problem Could we see a picture of this please?
