The snow is just because of poor quality signal
the signal coupler which is in the tv might be bad or your dish needs to be reset cause of the wind

Red, Green convergence lines are wavy


Projection TV sets have two very common problems listed below.

Problem #1) 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.
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...

*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

The most likely cause is shorted convergence chips and possibly a few pico fuses.

Black Vertical Bar


It will burn into the screen overtime. The Akai units have a resistor on the address board that feeds the PDP that usually has a crack in the solder on one or both ends of it. There are about 4 address boards that are right below the panel itself and the suspect one is the board right below the line that is appearing. Have someone with solder skills repair it.
