Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television

3 Answers

JVC AV-56WP74 When I hit the power button (remote or on the TV) power initially is applied, I hear some clicking (same as when it worked before), and then the power indicating light on the front starts blinking. No sound, no picture, no menus, and it doesn't react to hitting the power button or the remote. You have to unplug it to turn it off from this semi-on state. Everything was working fine yesterday, and nothing was changed until the TV wouldn't come on. Any ideas

    Tried to turn on tv, power button blinks then shuts off. No power, no picture, and have left unplugged for a while and tried again. Still nothing but a blinking green power light.

    Heartbeat sound when powered on, then the sound disappeards. No picture, no sound. LED power blue light goes blinking. Does not power off from the remote or front panel. Removing tv from the outlet does not help.

The JVC remote control, model JVC RM-SXVS60J, has stopped working as far as the bottom buttons go even though the top buttons work fine. If you can help, please.


Since the top buttons are working fine, i doubt that the remote is faulty. Sometimes its due to moisture/dust accumilating on the remotes board and creates a barrier against the board and the buttons. You may need to open the remote and clean the surface of the mainboard.

Hope this helps

The set is shutting down because a problem has been detected. Replacing the remote will not help. Count the flashes and call a JVC servicer to get an idea about what the specific problem may be.

Tv wont power up makes a noise but no picture


Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.

Big screen tv repair


There is a short in this TV set somewhere. The TV set is trying to come on but because of the short, the power supply shuts down. No if it is not the over current shutdown, it could also be the main power supply with an over voltage shutdown protection mode. These are solid state TV sets and should only be worked on by trained techs. Good Luck

TV, i plug it in, turn it on, no image, "on timer" light comes on.


If you dont hear a click theres a problem in the standby power supply. if you do hear a click theres a problem in the Main power supply or sweep supply. Get a good tech to look at this for you if your not a tech. Good Luck
