In all probability you need to have the convergence amplifiers replaced. A very common problem with all projection sets.

I have double image I am looking at array but not


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,Akai2_bing.gif,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

JVC 48 in rear


Probably the projection guns (my JVC had them fail on me). It started that way and eventually I had a triple image of what was on TV, one in red, one blue, one yellow, and all slightly offset from each other. The fix was new projection guns (thankfully it was under warranty as they were about $300 each).

JVC AV-48WP30 48 in. Rear... Problem


Your convergence I.C's ( integrated circuits ) Have failed. Replace Both I.C's with Stk392-150's. The unit is equipped with 110's. These are large IC's pn the convergence board located near the front of the unit. You need soldering/desoldering experience to do this job. I would recommend seeking professional assistance.

Struggling with an intermittent green (all over screen)


Do you have a color bar generator?
Connect it to the composite input 1.
Go in the customer menu select the color adjustment and turn it all the way down and tell me what you see in the back ground image from the color bars.
