JVC Television 56" in Digital Mode

sounds like the WP30 or WP74 series that has a convergence shutdown which will usually cause the thumping through the speakers. Unplug the convergence power board and see if the set will power up. Do not remove the rear cover the board is up front behind the speaker grille. Never remove the rear cover on a JVC rear projection as it can damage the digital circuits due to the safety interlock on various JVC models.

If the red line looks like a swoosh of red across the screen it may be the convergence Ic having an issue.

Hello

Change the channel to ensure the problem isn't with the current station broadcast. Check the channel at a later time to see if the broadcast problem is resolved.

The type of programming you are trying to watch determines the proper input source. Press the "Input" button on the remote control to change to the proper input source. For example, if the source is a cable or satellite service, press the "Input" button until "TV" mode is selected. A component device, such as a DVD player, will operate on a different input source, such as "Video-1."

Check the coaxial cable, which connects your television broadcast service provider to your television. You need to securely connect the coaxial cable to the "ATSC/Digital Cable In" jack on the back of the television, and the other end to the wall jack. If the cable appears damaged, replace it with a new cable.

If you are using a component device as the source of your programming, ensure the component cables are plugged into the "Video Input" and "Audio Input" jacks on the back of the television or that the S-Video cable is plugged into the "S-Video Input" jack on the back of the television. Connect the other end of the cables to the "Video Output" and "Audio Output" jacks or "S-Video Output" jack on the component device.

The LCDs in the tv are in 3 colors, Red, Green and Blue. They are out of alignment. Repair needed.

It has an NTSC (analog) tuner. You'll need a digital to analog converter to watch most stations. Low power stations are still available in analog in some areas.

I hope this helps.

That vintage of tv requires external decoder box. Its hd ready, but not digital ready. Repost the remote model number

Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

It is located in the front of the TV behind the speaker grille and access panel its the small narrow board on the left looking from the front. PLEASE NOTE do not remove the back panel on that model with the power still hooked or operate that model without the back panel in place or you will harm the digital section of the TV and cause major problems that model has a safety feature that will wipe out the digital memory if the backis removed while the cord is still plugged in
