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.

SOURCE: 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.

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.
