Projection sets have two very common problems outlined below.
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. The TV can also shut down when the convergence starts to fail.
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, RCA and others.

I got both stk392-040 installed and no luck....same thing with the out of convergence problem.....I also noticed that when i try to do the perfect focus feature i get no sensor data....Any other solutions?
I found 2 pico fuses in between the fins of the heatsinks 1 at each heat sink. No continuity at one fuse and will take it out circuit to be definitely sure. I'll let you what get when i replace it.
still no sensor data but pico fuse was definitely blown..replaced it and now ok . Any suggestions on the no sensor data for perfect focus option?
