    Tried the power reset, no change.

  • atmalibra Sep 07, 2008

    Before I crack it open, what am I looking for in terms of components? Is it a possible fuse or circuit board issue? Where would the ones for video be located at?

You may have a fuse located on the AC adapter or on the rear of the TV but this is rare. I would try all the simple steps first that we have provided. Then for parts for you TV here is a great site.

This site has been tested and contains no pop ups or spyware
www.partstore.com

Your board will have a fuse located on it so try that and then
you will have to check for any blown Resistors. I can smell if something is blown as soon as I open up a Tv so that should give you a good idea if the board is ok.

It could be bad color filters. the lamp works since you get a glow when you turn on the TV.

the only thing you can do is get a repair man or if its still in warranty, call JVC to come and check it out. you should not pay for this if its still under warranty.

Do not rate until satisfied.

Check if there's any blown components inside the circuit board like capacitor, ICs and Fuse. Mainly the power supply is the first to be affected. If you have no idea how to open the or check the circuit board, better have it check by your nearest TV repair center or call a tv technician

    The circuit board definitely needs to be checked because there's a bad component on it. Sometimes it can be obviously seen if it's burned or bloated, but sometimes you need to use a multi meter tester to check the suspicious component near the power plug.

A JVC LT42XM48 LCD Television set. Takes power has no picture or sound.


As a first step , if it is controlled via the remote, check that the remote batteries are good and that it is functioning ok. Does the tv show anything att all? If it does come on but shows nothing then it might be that the source selection is on the wrong kind of source, you can find on the remote whether this is so by going to the source menu which should probably be on digital. (I am assuming that you only have digital broadcasts where you are.
If there is no picture whatsoever ubplug the set and check whether the internal fuse(s) are ok.)

If the earphone jack works the set is ok---that socket can cause this issue if dirty or worn inside.

Check also in menu internal speakers are not turned to OFF or external.

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 lcd tv model lt40x776


LCD monitors are divided up into smaller strips. Each strip has it's own video driver. That strip has either lost it's power source, or the board is bad. Might just be a loose solder joint, if you are lucky.
