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.
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

I have seen this before--This set uses 2 convergence chips--usually they are STK-392-120 CHIPS--sometimes they will be flaky when cold--both chips need to be replaced and the set adjusted.

You can buy both chips on Ebay with shipping for less than 20 dollars. The chips are located on (usually) two metal heat sinks side by side and are about 2 1/2 inches wide and 1 1/2 inches tall---they will be black and have the STK number printed on them in white. If you open the set and locate them confirm the number that is printed on them.

Sooner or later if you keep using the set this way it will damage other parts around the chips.

MOST shops charge 300-400 for this kind of repair; I have done hundreds of these sets here for about 200-250 including parts, labor, house call.

If you cannot do the repair yourself look for someone in your area to do it--takes about an hour and any good tech can do it right in your house.

Make sure whoever you get to do it changes BOTH CHIPS--if not you will soon have the same kind of trouble again.


If you have any questions or need help reply to this post here.

I do this here for free so if this has helped you take a minute to give me a vote here.

Usually in this situation--just the 2 chips need to be replaced and the set adjusted!

Picture clear, then "grainy" can hit TV and will clear up


sounds like a cold solder joint in the tuner circuitry. Unless you can do it yourself it's probably not going to be worth the repair bill.
