Problem with A JVC projection television

Hello, I have a 56" JVC ( model #AV-56wp74) and when I turned it on today it appeared to be extremely out of focus. I ran Auto convergence from the menu screen and it didn't help any. everything appears double on the screen ,any word that appears you can read twice one of the appears where it should be and the other at a different angle in a different color. Is this a problem that I can fix or is this something that should be done by a repairman? Thank you for your help in advance, I really do appreciate it

The convergence ICs probably have a cracked solder joint on the foil side of the circuit board. Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. To fix this yourself, you will need to be able to identify the two convergence ICs,in this model they are in the front of the set, have a basic knowledge of electronics and be able to use a soldering iron (Use a dielectric compound when changing any IC attached to a heat sink). You will also have to do an alignment through the service menu. To find a servicer in your area go to: http://maps.jvc.com/cAscList/ It's the JVC servicer locater site. Call the repair shop listed and ask them what they charge for a convergence job on your set. That should help you decide which direction to go. Hope this helps.

Convergence problem


Hello,

Did you lock the adjustment into the TV's memory? This step is the most often missed. Please follow the directions on the Users manual or on the service manual on how to set your memory to hold the configuration.

Find the menu item on setting the convergence adjustment into memory (the menu should have an informational screen on this topic)

I hope this helps

Thank you,

A repair facility will charge 400 to 600.00 for the repair. Or you can repair it yourself if you can solder. As both convergence ICs need to be replaced. They are STK392-110 you can get replacement ICs at the following link with free instalation instructions with pictures so you can do the repair yourself. Heres the link.

JVC AV-56WP74 56 in rear projection convergence


If you remove the lower front panel where the speakers are then the small access panel you will see the convergence module right there in the front. It will have the two Convergence ICs attached to that heat sink. They are probably STK392-110. Then if you would like let me know and I will post a link where you can get the parts along with step by step instructions on how to do the repair.

JVC AV-56WP74 self check question


Each picture tube (red,green,blue) has a magnifying lens assy that sits on top. On each lens assy is a manual focus adjustment with a wing nut that tightens it. The image bounces onto the mirror and shoots it onto the front screen. If you're not a technician then I don't advise you to do this adjustment. You could touch something in the high voltage by accident.

JVC AV-56WP74 Problem


Yes, one of your convergence IC's have gone bad. They are located on the convergence board inside the tv and there are two of them. They are inexpensive and easy to replace if you know how to solder. Watch out for the JVC booby trap sensor on the dvi input card. Don't run the tv with the back panel off unless you have disconnected the DVI card from the main board. I would even cover the little sensor with black electrical tape. Then it is safe to work on the tv when it's open and on. Well safe for those who know what they are doing.
