I am guessing the CCFL tube is starting to burn out. Replacing is not impossible but somewhat delicate process.

Since the TV is that old i would recommend you to buy new TV instead when it goes completely dead.

Sounds to me like the digital pixeling that occurs with a weak signal. You have not identified whether this happens on broadcast/antenna TV, cable or satellite service, or a video input such as a DVD. This can be a common problem if you have a weak signal on any of those inputs. In any case, blowing out the dust will not help.

Unfortunately, there is a limitation on the JVC LT47P789 digital optical audio out. This audio output does not get the signal from any HDMI source. This is described on page 49 of the user manual. The manual is available from JVC here: http://resources.jvc.com/Resources/00/01/14/YA653ien.pdf . There is a similar restriction for the analog audio output from the TV with the HDMI inputs.

If you use the component audio/video inputs on the TV from your set-top cable box and DVD player, then the optical audio output will work. Otherwise, you need to find a way to connect the audio directly to the receiver. Some receivers have multiple HDMI input ports. These then forward the video signal on their HDMI output to the TV. Another option is to connect the analog audio outputs from the cable box and DVD player to the receiver. This may require resetting the Audio output from these set-top boxes to keep from sending the audio over the HDMI cable. With the Cinemate, you might need some sort of audio input switch or an HDMI converter and switch that separates the audio from the video signal.

I hope this helps. Please add a comment with more information about your devices for ideas on how to work-around the problem with this JVC TV.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

sounds to me like the fluorescent backlighting is going bad in the top half of your set.

sounds like the remote batteries could be bad or the buttons on the remote need to be cleaned. some JVC TV remotes, I'm not familiar with this particular one though, can be cleaned using a clean pencil eraser. Be careful opening the remote because some parts can fall out or you can damage the connections to the LED emitter that sends the signal to the TV. Also the solder connections on that LED could be bad.

you didn't say what kind of antenna you have attached to the TV. The antenna is very important and the type of antenna you need is based on where you are in relationship to the television stations in your area. Even being down a hill In the area can be a problem for antenna television. I had to put an antenna in my attic because an in-door antenna could not pick up the signals for the TV stations in my area, I am down a hill.

Flip the power breaker off and then on. See if that makes it work.
