SOURCE: Blue light

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: I have sound but no video on my JVC Lt-42x579

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Can you hook a JVC lt-42x579 tv up to your pc for netflix


It should be as simple as taking an HDMI cable (if your computer has an HDMI output) or VGA (monitor) cable and hooking it into the TV. From there, go to Control Panel and Display Settings, and click which option you want for the TV screen under "Connect my PC to a projector."

Dull/blurry picture


Sorry but You Don't.

Imagine taking a small Jpeg photo and blowing it up to Billboard size. It will be pixelized and dull.

Same with HDTV's. You can upconvert and adjust til your eyes turn blue, but you cannot take a Standard Def signal and make it look better by showing it on an HDTV. Some Standard Def material is better than others but ultimately what you see is what you get

Cannot connect my ipod touch


You need to press the [pcon] button while in the iPod mode of the TV. Then use the Touch to select the file you want to playback. It will playback on the TV. Ensure the iPod is set to output video to TV.
