Green Shadowing Around Images On Akai PT4398HD

So I bought this TV approx 2 months ago from a local guy for $80.00 because it has these green shadows. I have tried the "Perfect Focus" feature but it doesn't even get past 0%. I have gone into the menu and tried adjusting the convergence, the image has gotten much better but it's still showing the green. Any ideas on what might be going wrong?

I have a HCN4727w samsung. Red/green shadowing. Bowed image

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 or bowed
*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

Akai PT5598HDI Rear Screen Projection TV With Blue Shadowing

If the ghosting is like a 3D effect its your convergence ICs , but if its like a blue Halo around objects that usually means your CRT coolant has congealed and will need replacement. The blue is the first tube to congeal for some reason, followed by green. Red seems to be not quite as prone to this. It is a normal occurrence n sets about 4 years old to need the coolant changed.
