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 Sonyi have a convergence problem please help - 2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneeri have a convergence problem please help - 2_bing.gif/uploads/images/2_bing.gif" alt="2_bing.gif" class="h_mi" />, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Convergance problem on lower half of screen.smeared red and orange double vision,but only on bottom ofscreen.top appears out of focus,but not double visioned.

Howdy,

The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The part(below) Number is from Toshiba, they provide good advice on replacement parts. Make sure what type of IC's your TV uses first. The cost for this repair runs around $450.00 or more.

Replace the defective Convergence Output IC Part Number
23905094 (STK392-110) using the revised “T” version IC Part Number
23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version. Inspect the Convergence Output IC’s for the “T” type version as
shown in Figure 2. Replace the Convergence Output IC’s using the “T”
type version Part Number 23135090 (STK392-110T).

I hope this information allows you to resolve this issue.

I have a blue/green wave on bottom and on top of my tv tried to reset convergence, still the same, crosshairs won't line up.

Your symptoms sounds like a damaged convergence IC.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Most of the time you can just correct the convergence through the television menu. All that needs to be done is line up the blue and red to the green. If the colors do not move then there may be faulty components in the convergence circuit.

I hope this information allows you to resolve this issue.
