In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. /

Either the disc or the player likely need a good cleaning. Clean the disc with a soft cloth, clean the player with a good cleaner disc.

A firmware update might fix it. Call an authorized servicer, explain the symptom.

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

Turn on JVC 32" flat screen TV and got the JVC logo then sound and no picture. Then next day, only got the logo, no sound or picture.


There is a way to reset television. I have a jvc 42inch that was just going to main logo screen and not beyond it. If i remember correctly you unplug the tv hold power button for 5 sec on tv then let go plug in and start. If that dont work unplug and then plug and hold power button on tv for 5 sec. It is 1 of those combinations. My tv worked after that. I googled my problem and a website listed that some tvs need to be reset.

JVC TV (LT-32E478) Stuck (loops) in standby mode...? Buttons on TV have no effect... Will not turn off?


Do you mean the JVC Logo keeps appearing?

If so, call JVC for the software update. I believe it may even be posted on their site. You can check in the TV menu to verify. You should have F108 or higher.

If the update doesnt apply, you need a Digital PWB for the TV because it is defective.

No video input -- all ports -- for JVC LT-37X688


JVC may allow warranty exception or some accomodation for 15 days out. You have 2 seperate issues

1. White lines spreading is probably a video process problem. I think this TV has 3 Boards inside. Middle one is most likely suspect followed by the one on the Right

2. HDMI input not working is because they were turned OFF. JVC TV's have a sensor that will shut off the HDMI if the TV's back cover is removed. This must be reset in the Service Menu.

Besides bounching this off a concrete wall for some satisfaction, try unplugging it for a couple of hours at least four hours and then plug it back in. Wait for it to stop loading and you may be able to watch one movie, two if your lucky before it starts flashing again. I've even sent mine to JVC for repair and got a year out of it but it's flashing again. This JVC item is the biggest piece of junk out there, if you read up on it it's had nothing but problems. Save yourself a lot of headaches and buy a new one and chock it up to experience.
