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.

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.

I would take it in to be serviced. It may need a control board. Just to bad there is only 1 year warranty. You should get 3 to 5 years out of any LCD TV. Some are made cheaper than others. Good Luck.

Testimonial: "I purchased a 3-yr extended warranty on it so it's covered. Someone came, spent 2 min just looking then said they ordered a part (power board?)for it"

It is the power supply, you need to replace the bad electrolytic caps and/or replace with a new power supply and that will take care of your problem.

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."
