Jvc hdtv power problem

I have a 56" jvc hdtv that powered down while it was on and the only thing it is doing is the blue light on the power button and lamp light are flashing. Is this something you can help me fix?

    Is this a RCA, or JVC and is it flat screen or DLP plasma etc? Other words do it have the crt bulbs?

  • Lashawn Robinson Dec 22, 2007

    There is a thread on here that shows how to replace lamp or if you have customer's manual you can find where it is. but you can check and see if door is closed and see if lamp is out.

I have a JVC-HD projection TV model 56G786 and all of a sudden it will not power on. When you try to turn it on the blue light on the power button goes on but after a few seconds it starts flashing and...


The JVC 56G786 users manual will not give you a clear or specific answer about confirming bulb failure with the LED lamp or power indicators located on the front of the TV.

If the TV was operating normally for an extended period of time (months or years) and will not start, the problem is almost always bulb failure. If the "Lamp Replacement" warning previously appeared "On-Screen" and the TV will not start, bulb has failed.

The first step in a "no picture" situation with a JVC LCD Rear Projection TV is bulb replacement. There is no way to measure the bulb. Sometimes the bulb is visibly broken or damaged when it fails. Remove the lamp cage and have a look.

The JVC Lamp Gallery has all the JVC models and lamp numbers listed. There is also a link to DIY JVC bulb and lamp installation.

If a good bulb is installed correctly and the TV still does not start, you need a technician. There are no user serviceable parts other than the bulb. Failure of ballasts, power supply boards or controller boards is rare in these TVs.

Tv power button comes on and blue lights flashes but no picture and makes a clicking sound out of the back

This is the start relay trying to fire the display. I suspect that the caps on the board have fried themselves. It's not a DIY job as the replacement board needs to undergo tuning and realignment with special tool to create hatch pattern and to align the convergence or color engine.
Those that have tried thinking they can do what a PC fix can usually end up sepending more money and down time than if they has taken it to a professional.

TV is not responding

Your description does not tell me very much---You have a JVC AV-56WP74 and it does not work?

If the power light up front which is usually blue in color just blinks I can tell you a easy way to know exactly what is causing this problem.

If when you turn the set on the blue power light just blinks---that is short protection--most of the time a fairly cheap fix----LET ME KNOW WHAT YOU ACTUALLY HAVE GOING ON.

I am here to help---I do this here for free.

Do not hesitate to ask me for help or advice.

Power wont come on and blue power button just blinks for a while

Do you hear a thumping coming from the speakers when the power switch is pressed? If so, you have a shorted video IC or your convergence ICs need replacing.

Please help!!! Problem with JVC DLP TV

You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

JVC HD DILA 56G886. replaced lamp and now it shuts down after 10

we found that it is an auto shut off system on the TV due to over heating. The lamp, if not cooled correctly shuts down. We added a mini fan in the back and it seems to work fine now.
