If you have the led light on or blinking just replace the mainboard, if you dont have any led light at all, then you need to replace the powerboard.

Why is the Power lamp flashing on my JVC LT-37DS75SJ LCD TV


In most cases your power supply has gone south. You can likely get a power supply repair kit from www.TvRepairKits.com . Its usually a fairly easy DIY fix

I have a lip sync problem with a JVC LT-19DD30J LCD TV


Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board
power%281%29.jpg2_23_2012_11_31_16_am.png

After replacing blown capacitors...it should work again.
caps%281%29%281%29.jpg

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Hope it helps

JVC TV, LT-26C31BJE Sound but no picture. Is it likely to be a low cost repair, or buy a new tv time?


Hi cross_keys,
Before thinking of a new set, try this first.

You may power on the unit in the dark room and directly shine the flashlight to the LCD monitor. You will barely see an image or picture because the fault is either the inverter board or the lamp (backlight). You may isolate the problem but it will require you some tools and test instruments. Also, you must know some basic safety precaution in electronics troubleshooting.

Best way to find the faulty parts between the two you need to test the output of the inverter board. You can do it using the voltmeter or if does not available you may substitute a two 12v car bulb in series to the output of the inverter board. Powering on the unit and look if the bulb will glow or not. Yes, your lamp was busted. No, the inverter board fail.

You may look online for the replacement of defective parts. http://shop.ebay.com/i.html?_nkw=LT-26C31BJE&_sacat=0&_odkw=42RV600E&_osacat=0&_trksid=p3286.c0.m270.l1313

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

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.

JVC LT-26DF7BK won't turn on


Hi I had the same problem with my LT-26C31BJE. The TV just stuck in standby mode. If you tried to turn it on, it seemed like it tried to power up, but then reverted back to standby.

I solved it this way. I took the back off the TV (unplugged of course) and made sure all visible contacts were home (they all seemed to be). Also to the right of where the power lead enters the box there is a small fuse, 250V 6.3 W. I replaced this fuse and the TV now works fine.
