Question about JVC AV-65WP74 Rear Projection Television

Video Inputs not working

I just changed out the convergance mods, once I have the board back in, had a great pic but no sound. In getting the sound back up, all of a sudden, the video inputs, all 4 do not work now. It was working fine initially. Is there a specific wire/board/chip which all inputs lead into? The three in the back and the one in the front? Is it maybe a setting on the menu feature of the remote? Thanks for any help you can provide.

Did you have the back of the tv open while the poer plug was plugged into the wall? If so the set will need some serious repairs as that model has a safety feature where if the back cover is removed without removing the plug from the wall it wipes out all the digital and video circuits. You have to defeat the safety feature before removing the back panel, and if you plug it in even for a second with the back removed the damage is done.

My LG HD tv screen suddenly went green. sound is


Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

All of a sudden, no sound on PS3, great pic though. Using HDMI cable...have checked all connections, reset PS3, etc. Still no sound! Guy from Sony said my HDMI cable(Monster) could be bad?! No sound, but...


I agree with the guy from Sony, the reason for this is the HDMI cable should support the transfer of audio and video over the same cable, if your only getting video over it, the cable could be defective, or its possible that you have another cable in the spot where speakers should go that is over riding the HDMI.

What exactly is the HDMI cable plugged into? Is it direct from TV to PS3?
If you have a stereo set lying around that supports HDMI - try having it run through that.
Is the TV muted? check if you can get sound while watching normal TV channels.
Worst comes to worst, use RCA Plugs remembering that the composite video is (yellow) and stereo audio is (white and red). You don't need to connect the composite video, but connect the stereo audio.


If this did not solve the problem, please leave a comment and I'll get back to you once I can =)

Sounds like a video board problem. May also be the convergence board. You might get some freeze spray ( a component cooler that comes in a spray can ) and while the set is on, spray the boards and see if the problem temperarly corrects. This is to isolate the problem. Once the problem is isolated, you can change the bad component. Good Luck
