    I have the same problem. The lower third and the top left hand corner. Does this sound like the same fix will work?

    The lower third of my television is also showing double. How difficult would it be to change the convergence IC my self and do I need more than 1 to fix the problem?

We just started having convergence problems with our WS65905. I performed the standard convergence adjustments and have the red/blue bars perfectly aligned. On the screen we have green and pink bleeding...


Yes, call local tv repairman to fix the issue because convergence output section got some problem like cold/ dry solder joints, devalued few resistors that can also cause of these symptoms and defective convergence output ICs are also one of bad convergence reasons in rear projection tv, all that happened because of heat and high amount of current drain in convergence circuit and its common problem of rear projection tv.
Visual check by experienced tech is necessary and repair would cost you around $250 to $350
Hope these info will help you.
Thanks.

Double picture & color problem


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

Are you able to do a multipoint convergence adjustment in the convergence menu? Do the red and blue adjustments move in all four directions/ Let me know and I will try to assist you.If the anser is no to either problem you will need new convergence ICs and convergence resistors.

Color seems to be pealing up from the bottom of screen



If the screen is bouncing...expanding/shrinking you need to get a repair kit from www.TvRepairKits.com

If your screen looks 3d in color, has a stationary bow, or if you can't adjust one or more colors from the "convergence" menu you need to buy a convergence repair kit. You can get one from the same site listed above. 

Hope this Helps,

Arched pink lines across screen. Now green and pink double stacked wording.


Projection sets have two very common problems.

The first common problem is convergence


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.

The words on the screen is doubled or trippled.


Go to the picture control menu and turn the color to minumum so that you are watching a black & white picture. Do this to determine if the color offset affects the overall screen or just the lower corner. If the center is off, go to the convergence adjustment menu and align the red and blue onto the green as described in the owners manual. Some models also allow you to align the outer edges as well. If the bottom is still bad you may have a problem in the convergence circuit. If the outlines are not seriously bowed or distorted a minor convergence toutchup by a qualified technician should correct the problem, otherwise parts are involved and the repair is considered major.
