Screen occasionally has distorted/wash-out colors (white become blue and bleeding)

Try another source device to verify if the issue occurs with all source devices or just one.

I have some distored blue color across the screen

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

The color is distorted and the picture blinks. I've replaced the lamp twice before and i don't think this is a lamp problem.

color distortion (bleeding colors, or overwhelming of one color)on these tv's is commonly the optical engine. that might make it unecinomical to repair

I have color bleeding or washout in solid colors? does that mean the lamp is going bad?

I am not sure which set you have, but, when colors are bleeding on a projection set that is a good indication that the tube is going bad. The color that is dominate, red, green or blue, this will tend to bleed across the screen. If I had more information on your set I could give you a better suggestion, but if it is a tube it will be a costly repair.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Thanks for using FixYa

Picture is distorted

Is your TV near anything magnetic ? This causes picture issues. If the thing is a tube TV then you can fix this fault with a magnet. Call 0845 20 20 118 for help
