WENT TO SLEEP WITH CABLE REMOTE ON WHEN AWOKE PICTURE WAS SNOWY AND LOUD. TRIED TO FIX WITH CABLE REMOTE NO SUCCESS, WENT TO TV REMOTE AND WAS ABLE TO GET THE PICTURE BACK BY USING DEVICE BUTTON AND ADJUSTING TO COMP 1. THIS HOWEVER LOST THE SOUND, WHEN I PUSH THE VOLUME BUTTON IT SAY AV RECEIVER:VOLUME UP. CALLED BRIGHTHOUSE CABLE PROVIDER REBOOTED, SCREEN WENT BACK TO SNOW BUT HAD SOUND, AGAIN REGAINED SCREEN WITH DEVICE KEY BUT LOST SOUND????????????

Sounds like a bad timing control board...Tcon...that generally causes picture issues when there is sound.

The remote doesn't effect the channels, I would say you have poor signal or interference from another device nearby.

Check the interconnection cable. Try a new one. Check whether proper source i selected with TV. Check whether both VHS and TV powered ON. Gopakumar Gopalan Google

What to do if you have an all snowy picture (blue screen or the TV displays unusable signal-no signal or no sync)
1 – If you are using a digital cable box or satellite receiver (make sure it’s on) and be sure your TV is set for either CH3 or CH4 (which ever you usually view it on). If you usually view it through video inputs (video1 or 2 etc.) make sure the appropriate input is selected.
If you still don’t get a signal see if you get picture using the DVD or VCR (if available) if you do than plug the satellite or Dig. Box temporarily into the place of the DVD (unplug DVD) you may have to use some A/V cables (RCA yel./red/wht like the ones on the DVD) to hook to the tv from the sat./dig. box. If you get a signal then the sat./dig box is ok. If not the Sat./dig box is not sending a signal and is either defective or needs to be rebooted (unplug wait 5 min try again).
2 – If you are using standard cable or antenna (source) if possible check that the source is good by connecting to another TV. Otherwise try running the source into a VCR and then out to the TV using video inputs (RCA yel./red/wht like the ones on the DVD) and then selecting the appropriate input. Try seeing if the VCR plays using standard CH3 (or CH4)
If the VCR plays on video input but not when connected to CH3 (CH4) then the tuner of the TV may be defective – see if you can use the VCR to change channel using the VCR remote.
Be sure to vote/rate me if this helped Thanks!

The set needs to be switched from antenna to cable in the setup menu. It is capable of either antenna reception or cable reception. Ch 2-14 are the same frequency for antenna and cable but above 14 they are different. That is why the picture is stoping at 14. After you switch it to cable auto program again. Thanks for using fixya.

when the screen becomes snowy, it means that something in the cable box is being overheated. what you should do is take a small desk fan and hold it beside the cable box. this has happened many times when my family has played on their xbox 360, and the desk fan solved this problem. i hope that this helps!

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.

the 3 or for setting on the vcr is on the back( a switch)
or if the cable box has a channel 3 or 4 setting on the back of the box
but otherwise the tv may need some work on the tuner or need a new tuner

Probably need the TUNER either fixed or replaced.

update: Well, we ended up calling the repair man and we had a bad Y-sustain board and also a bad Z-sustain board. According to the guy who fixed it, it was due to over use of the TV and using main power button instead of shutting off through the cable remote. 650.00 later and a few weeks later, we now have a fixed plasma. No real suggestions on how to get more life out of the new boards.
