We have a JVC plasma TV in our workcenter that looks like its on its last leg! The picture quality/resolution is horrible grainy onnthe right side as well as on the top. When we turn to a blank channel, it looks like the JVC emblem has been burned into the screen and sometime we can see it when we watch movies that have dark scenes.
Is there a way we can fix this or do we need to buy another one?
One more thing: The TV stays on 24/7, we watch the TV, the flightline, and surrounding parts of our installation for security purposes.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Resolution is 1080P (1920x1080). It is 3D ready, and has very good reviews from owners regarding picture quality and overall value. One limitation you will encounter, is that it is more difficult to see the screen from the side, than it is with LCD or plasma. Also, due to lamp warmup times, it takes longer for the TV to turn on. However, you will save a lot of money by purchasing a DLP versus LCD/LED/plasma.
unfortunately cable does not give you the best quality picture and "fuzziness ' is the reduced resolution being displayed on the tv. the easy way to check the picture quality is to get a decent hd antenna and scan using it for free hdtv signals, if these are also fuzzy, on all channels then the tv has a problem but if it is only on a few lower resolution channels then its just the way it is until everyone is hd 720 or better.
The sharpness of your picture is dependent on the resolution your TV and device(s) are capable of producing. This TV is capable of showing video in resolutions up to 1080i. 1080i is a good quality of video, so the lack of clarity in your picture is likely being caused by your video source. Basically, the principal of Garbage In, Garbage Out applies here. If your video source is low resolution, even the best TV won't be able to produce a clear picture from it. If you're using VHS and standard definition cable, switch to Blu-Ray and ask your cable provider about high definition tv. Make sure you're using the proper cables (ie., HDMI) as older types such as composite can't support high definition video. Once again, your TV wont polish any poop for you, but play some decent quality video through it and you should notice a world of difference.
Doing some warranty work for Visio, I ran into this same problem. I replaced the video and power boards, among other things. Turned out to be a bad panel, which isnt viable to replace. Best to get Visio to agree they made a lemon (as all their products are in my humble opinion) and have them send you a new tv, or even better, buy a tv that is NOT a visio. You can get great deals on LG and Samsung these days, both decent quality tvs.
Match the PS3's output resolution to your TVs (in this case 720p). Don't sit too close, otherwise you'll start to see individual pixels. Make sure the HDMI cable is good quality. As for picture settings, they will very so much according to the viewing conditions that i cannot give you settings that are gauranteed to work for you. But sharpness should always be 0 when dealing with HD content. If you want to really get the best picture from your TV, try using a THX disc to calibrate it. Luckily these are normally included on Disney PIXAR DVDs, so go find yourself a copy of CARS or something. Follow the instructions of the THX setup, and you should have youself a sweet looking picture in no time.
The TVs produce picture using entirely different methods. Usually the colors and especially level of black color are better on plasma, LCD will have some trouble various shades of gray and black especially shading on peoples faces etc.. This is not a defect in the LCD just a limitation in current technology.
Some one might have messed up with your camera.
some one might have changed the resolution, aperture, manual focus etc of the camera.
Try setting them according to your needs or try resetting the camera.
Sounds like your high voltage section, or your main power supply is shot. DO NOT OPEN THE BACK OF YOUR TV.
The chassis of the TV ( any metal inside the plastic outer shell ) is Electrically HOT ! The High voltage section has upwards of 30,000 ( thirty thousand ) volts running to the picture tube...so DON'T TOUCH ANYTHING.
THe Humming noise is the TV Drawing a lot of current and trying to work. Don't continue to let it try or it will be an even more expensive fix....pull the plug !!
WHAT YOU SAW:
"The picture could condense to very thin and then go back to orginal size"......this means that the vertical high voltage section was collapsing (the high voltage for this part of the picture has failed ) and coming back ( normal picture )........this means that some part in the HV section was on its last legs. Now it has no legs.
Best thing you could do is take it to a shop. I have a 32" JVC of the same era and love it. It has given me no problems at all, and even though the price of a new "Tube" TV is extremely low, the picture quality isnt anywhere near as good as your old JVC. Personally, I would at least get an estimate to repair. Good luck....Rob
