My jvc 56" proj. tv pops several times when i turn it on but the screen stays blank


Ok, I suspect one of the two convergence chips is shorted, this is usually the most common reason the light (blue?) just blinks.

I can tell you in a easy way how to prove this without replacing any part--

What kind of skill do you have?

This entails removing the front grill under the screen and disconnecting the Convergence board behind the inspection plate.


I am here to help--

Double picture


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Convergence problem with my jvc tv


Its actually a easy repair but its recommended that the convergence resistors need replacement as well. You can get the parts at the following link and they provide free detailed instructions with pictures. You need two STK392-110 Convergence ICs and you would need the JVC convergence Resistor kit #1 also. 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.
