Question about JVC LT-32X787 32 in. LCD Television

Open Question

Digital breakup I have had my JVC 32 LCD for about 1 year. In the last two months a problem has showed up. The digital picture breaks up and the audio gets delayed, green and red pixels appear and breaks up the picture and audio. My cable company replaced their box and it worked fine for about a day. Then the problem started again. I do not have a digital receiver. When the video breaks up you can hear a small click coming from the LCD, You hear the click and the sound and audio brek up...the next day the reception is fine...it is an intermittent problem. Any ideas of what to do to fix this????

SOURCE: JVC GM-P420E Plasma no video green screen

the problem is with the micro processor on the back of the fx-1169a board (gm-p420ug) this is the board the inputs connect to . yours may be a diffrent p/n due to yours bein a "e" extention model. to repair this problem you need to remove the processor from the socket, remove the socket from the board and solder the processor onto the board. the processor is ic002 on the back side the problem is thermal in nature due to cold solder joints on the socket. i have fixed this problem many times by using this method.

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.

SOURCE: No Picture

I am deeply sorry but you will need to replace the backlight bulbs. These are not available.

Look on Ebay for a 32" JVC with a broken LCD Screen. Buy it and use these bulbs to fix your TV. I am sure there will be a few good ones in the broken TV. It's that or list it on Ebay for $50 and expect to get about 200-300.

LCD Panel repair for this problem is $500 for parts so you are stick with repair yourself or sell.

I will keep you posted when the guy will return.

JVC LCD TV (LT-42X688) input panel not working!


1. This TV has setting for the HDMI input that allows you to select the HDMI Audio or Analog(red/white wire) audio. Make sure this is correct

2. Most cable boxes are DVI not HDMI. If DVI then you actually do need to use those Red/white cables. If HDMI, refer back to #1.

3. The cable box has a setting to select the Audio output, HDMI (digital) or Analog(red/white cables). Just like #1, this has to be set.

4. Contact your cable company to help you set up the box correctly. JVC can probably help you check the TV

Picture blacks out after a few seconds after turning on the tv


Anytime an LCD has a shade of pink, that means the CCFL lamps are about to go out. Now that you have a black screen, I'd say you just need some new bulbs.

Top of the screen Picture Problem


sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem. good luck.
