Sounds like the power supply has an issue. Sometimes unplugging it and holding the power button for 30 secs. or so MIGHT resolve it. If not, possible blown caps on power board.

If you can see a dim image when you look at the screen at a sharp angle then you most likely have a faulty inverter board or faulty CCFL lamp/s.
Most likely faulty inverter board which supplies high voltage to the CCFL lamp/s.

JVC LT-32P679 Blinking Power Light, Automatic Shutoff

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.
