No. You have bad convergence output ic;s and probably at least 1 burnt resistor. This liely will have to be reconvergec in the servcie menu after the aprts are changed.

I have a JVC AV32950 TV that started getting wavy lines moving across the screen from left to right. Any way of getting rid of the lines?

Does it get the lines on any channel? Do the lines move across at screen slowly?

Double vision on tv with purple and green colors

Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

My 56'' jvc av56wp30 tv screen is doubled only twords top o screen

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

You can see some more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

DOUBLE VISION AT TOP OF MY SCREEN. DISTORTION.

Good Day, wars;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

1st guess is bad convergence ic-either IC804 or IC805. Both are part #STK392-110. May be bad connections in convergence circuit, or open resistor(s) As for too much green, not sure, shouldn't be because of convergenece circuit, possibly green CRT screen voltage needs adjustment.
