Have you ever replaced the lamp in the TV? Usually the owners manual will tell you what the flashing indicators mean on the front. The lamp would be my first suspect.

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.

No picture just clicking


I don't think I need to pay you so you can tell me that I need to have some one come in and repair this. It sounds like it neds a new relay and I don;t think you can fix this on line.

Red convergence will not line up on my jvc 56 inch i art projection tv model # AV-56WP74. PLEASE TELL ME WHERE CAN I BUY THE KIT SO I CAN FIX IT MYSELF!!!


You need to pull the front grill cover/panel off the front of the tv. Remove screws (4) from back that hold it on, also 2 small ones behind front video input door. Then remove access panel. The ckt board closest to you is the convergence amplifier board. You should replace both amplifiers (stk392-110 or 120) and any burnt/open resistors you find near the amps.(use the same value resistors as the corresponding resistors in the blue amp ckt)

How to do convergence on a JVC 56 in rear projection HDTV


. It is more difficult than batteries on a remote.

You access the convergence board through the inspection plate that is located behind the front speaker grill.

You remove the board, determine if any resistors are burnt, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If you haven’t misadjusted it too badly, do the auto focus and it is back to where it was before IC failed. If it is still misadjusted badly, then resistors may be wrong value or open.

If you live around Calgary, try me instead:

or try the find a repairperson part of this website, maybe you will be lucky and someone is listed nearby.

Most rookies doing this job will cause damage and not be successful, and pay double for someone to fix their mess.

For a 10 years old TV, it might not be worth fixing it. Save your money to get a new one once this one gives up.
I would keep it running using with the back cover off using that fan to keep it cool.
Hope this helps.
