Blue tint across screen and black shadow of sort

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

The picture projects the image with concave lines on the edges. I'll explain further: somehow the picture is distorted in a way that bends the four edges of the picture in a curved-concave manner so that...

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

We are getting ghost images and the color is not correct

I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

Concaved screen image, no response on vertical blue converge

I've read some similar problems that tend to indicate that it is a convergence chip problem, so i ordered a convergence kit. I will update you as soon as I get it fixed. Thanks

Getting double image in colors

this is a lost of convegence power. first check to see if you have the convergence option in setup menu. if you do not then i suggest you read the fl231 problem in the tips and trick section. otherwise there a good chance u would have to replace convergence power supply board

Distorted image and color

sounds like the convergence ICs have failed. Will the red and blue move in all 4 directions when you try to adjust the convergence? If not the convergence ICs are bad replace both of them also check the resistors that power the ICs as they may be open as well.

Image convergence problem

Are you able to have any control over the red and blue convergence in all 4 directions? If not you need to replace the convergence ICs they cost about 10.00 each you will need two of them. A classic sign of bad Convergence ICs is a distorted picture at the top and bottom with the convergence out of alignment on at least 1 color. Let me know if you need anything further.
