Cable system is grounded to electrical system. Most electronics have fuses inside. Open it up and look for blown fuse.

hi,you need to auto search first your your t.v set if nothing happen possible defect is the tuner.

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

The IR sensor in the tv is probably weak, you could make a mountain out of a mole hill and get it replaced (using your friends receipt ^_^) but there's nothing to be done about the sensor.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.
