Question about JVC AV-56P575 56" Rear Projection HDTV-Ready Television

1 Answer

Power issue, clicking noise, turns off

No other symptoms noticed. One day won't turn on. Plugged TV back into the outlet, Front power light (blue) comes on, then after about 3 seconds, there is a rapid "Clicking" noise near the power supply (where the cord enters the TV set in the rear bottom of unit), and then the set turns off. The screen is never engaged. I do have the unit plugged into a good APC power strip surge protector, which is operating normally. All other devices operating normally. Is this the power supply? Can I replace it?
Thanks a million. - Steve

    I am having the same problem. I had a repair man look at it. He told me that it was the red CRT. There was liquid coming out of it. Well he was supposed to order the part and come back to fix it. He never showed back up again. His number is no longer in service. Now I am having trouble finding someone to work on it, since it was taken apart. Would like to get an idea of what I need to do. Thank you

The clicking is the power on relay closing and opening. This happens because the TV has several built in safety systems that will detect and over voltage and over current load situation.The power supply starts up for an instant, senses and overload of either or both kinds and then the safety switches trigger a cutoff. When this happens the power supply will not start up again because another circuit called a latch keeps it disabled. By unplugging the AC cord and trying to start it again releases the latch until the failure triggers it again.
On these TVs the power supply is rarely the cause of the shutdown. Something further down inside the TV has failed. Replacing just the power supply will not fix the problem. The most common reason there would be an overload would be in the high voltage circuit that lights up the 3 CRTs, next would be the coils around the CRTs that bend the beams to make the picture. This is normal circuit aging and wearing out. Unless you are very skilled with trouble shooting TVs I would recommend having a service center look at it. An authorized JVC shop would be your best choice because they will have access to the manuals and bulletins and have probably had other similar JVC units thru their shops.

My Coby LEDTV-2426 24 No Power


Switch off TV, switch off power, remove plug and wait for 48 hours and retry. If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

Blinking red light in front of tv (lamp) and noise coming from tv as well.


Hi,
The Lamp light of the TV blinks when the Lamp of the TV requires replacement. The model # of the user replaceable lamp block is XL-2200. You can download the manual of the TV by clicking here. Refer to page # 76 of the manual for further information. Follow the steps below to perform a power reset first:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

Have an insignia tv that won't power on...was off..made popping noise...won't power on. checked power in both the surge protector it was in & wall. all other items plugged into surge protector work....


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

TV loses all power


I had same problem. Finally figured out the power supply was the problem. I ordered a generic replacement and it hasn't shut off again for over a year. The only thing I have notice is there are noise lines in the lower channels (1-6). This may be beause the Toshiba power supply may have a noise filter in the power supply. But the generic was $30 compared to $80 Toshiba
