Going to be a shop repair----only way you might pinpoint which board is bad is with back off and set on----take a high speed small fan and see if any board or area reacts by color returning to normal---can use a handheld hairdryer set to NO HEAT/COLD to do this but a fan works faster.

Then take the gamble and locate and or replace that board--my money would be on main where tuners and signal/control circuits are.

SOURCE: Poor picture quality from 130 degree viewing angle on my LCD tv

It is unfortunate but "off angle" viewing will compromise the picture especially on larger TV's and LCD. Off angle viewing can come from the vertical axis or the horizontal, as you described. This is clearly illustrated with a laptop computer. Adjust the screen forward and back (vertical plane) and you will see very clearly that you get the brightest picture in a very small amount of range of the screen. Likewise, viewing from the side compromises picture as well.

I also don't believe that the delay is indicative of any problems.

SOURCE: 32''LCD TV Polaroid FLM-3201 - picture crackling and color fading

Sounds just like a loose solder connection. The trick is finding it. I would start with the microchips and the large transformer. Otherwise, it could be a capacitor starting to short out. I would give both options a 50-50 chance to be the problem.

SOURCE: JVC 42 inch LCD HD TV has no picture or sound

utencilio posted this fix. It worked for my JVC LT-42X579.

Okay, I found a fix! Called JVC, spoke to somebody there, here it is:
1)unplug the TV completely, no wall no power strips, completely
2)wait 10 sec
3)plug TV back in and Turn it on, the light will still be doing the same thing
4)wait 30 sec
5)ON THE TV, not the remote, locate the menu, volume (-) and power button.
6)while simultaneously holding down the menu and volume (-) button, pressed the power button ONCE and continue to hold the other 2 for 10 sec.
7)on the remote control, go to menu>settings>system info
*** now this I know as a FACT will work on systems that display: JVC - ver.5.32FO001, but I don't know of any other versions***
8)press the mute button on the remote twice
9)unplugg TV again and wait 10 sec.
10) plug TV in and turn on

It SHOULD be working normally now... Thanx to the guys a JVC support for this one, I know it seems like an obvious first place to look, but sometimes it isn't. I for one checked online forums first

SOURCE: JVC LT 42x688 no picture just sound

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.

You need an Analog Board. It is the one in the middle. You can find it on ebay for $50 I think.

The color is not working. I am being informed to change the motherboard. 42 inch JVC. where can i buy the orignal from?


Please elaborate on the color not working:
1.Is the picture clear just the color shift is off, or is the picture like watching a black&white Tv?
2.If the colors are just faded, non-contrasting, come and go, go into the programming section and reset adjustments to achieve the desired picture.
3. For colors that fade in and out ( come and go ) absent any information as to the source ( cable, antenna, satellite ) check all source connections, disconnect and reconnect while keeping a an eye out for loose, damaged, or dirty/corroded connections.
4. If determined that that the television does have a component fault, I question the mother board designation as these units have several compartmentalized card/boards. Replacement board availability and location ( as I do not know your location ) is available from :

My flatscreen tv is distorted


Speakers can cause problems with the correct display of video on TVs but usuall it only concerns direct view tv. Projectors should not have any problems or flat screens. I think you have a different problem Explain better what you mean by distortion in the JVC. Let me know and I will try to help you.

Faded Picture


I would have to say it does sound like the CRT is reaching its end. The thing that points this out that the picture gradually gets a little bit better as it warms up. It most likely isn't worth the cost to fix it.
