Question about JVC LT-42X688 42 in. LCD HDTV
I have a JVC LCD TV (model LT-42X688)and the rear input panel is no longer working!
I am able to watch TV through my digital cable box using HDMI cable, however I have no sound through the TV speakers. I am using my stereo speakers for sound.
No DVD, no Wii, nothing through analog - HELP!
Has anyone else had this issue? I am not a "tech genius", but like to think I'm ok.
The TV is 6 months past the 1-year warranty.
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

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.

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.
