I have mistakenly plugged a 120V into a 220V power socket. You know what happened next. I need to replace the entire power supply board. The problem is that JVC has been phase out in the Philippines a long time ago. I was hoping somebody can help me with my problem. I need power supply baord for this model. JVC LCD Tv Model No. LT-32P510
There is no one that handles that part that I can find.

I have the same problem. I finally convinced JVC's tech support to help me out (they **** by the way) and I got the schematics for all the boards in the unit. From looking at them I believe it is the Digital Signal Board. I will post results soon.

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.
SOURCE: i have the same problem with my tv.
take back off lie flat
where the hd leads go into that board remove the screws at the top and bottom as its one long unit top to bottom
unscrew metal shield as well
remove all cables from board 2 ribbons are locked and require clipping down then ribbon removes
flip board over remove metal can to expose board notice 2 TSOP chips at top look att the pins one should look dull and not shiny
to fix i used heatgun a quick blast on pins sorted problem out
mask off board and chip around with metal etc... to not damage board.
SOURCE: My JVC LT-47GZ78 will not
The blinking indicates that the protection system of the power board from the tv has detected a short on one of its outputs and has cut the power to it to prevent further damage - the clicking is made by the main power relay being disengaged, repeatedly, by the protection.
You should count the blinks - it's an indicator of what might be faulty. If the blinking is continuous then the problem is either in the control processor or the power source itself. To find out which and replace the appropriate board the tv will have to be opened and inspected.If you;re lucky it will be just the electrolytic capacitors on the power board. This is how you replace them

If there's more then you will have to check the voltages on the power board to find out what elsehas failed . If you can't do that then it's time to call a repairman.
hi. I had the same problem and to fix it you need to take printers right-side cover off. Underneath you'll find a Power Supply Board - hidden under metal cover. Take it out and disconnect two cables from it. Now, I had to replace an fuse 125V 4A and varistor E241AD 83P on the Power Supply Board in mine HL-2140. It works fine now.
Note: I could not find the exact replacements in electronic store so I used:
- fuse: 250V 4A
- varistor: FNR 10K241 (241 is the important number)
Hope it helps.

Is it repairable?
Of course it is but it is going to need some thorough diagnotic work to locate the things that are damaged. The cost of having that done could be more that a new set.
