Bluring of colors

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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Converging problem

This is a rear projection TV that uses three color "guns" in a cathode ray tube . They are no longer converging at the screen. The convergence problem is usually a sign of something else gone wrong with the high voltage.
Do NOT attempt to open this set yourself. This type of TV can have LETHAL voltages inside for WEEKS after it is unplugged. The repair and convergence calibration will require a qualified service technician.

Can bad color wheel cause lamp to not turn on

Actually yes, the thing is that the color wheel is also part opf the light engine system and if it's not working, it will prevent you to see an image, you will need to replace it and it's most probable to fix your issue, of course since it's a Samsunt Tv, you need to identify the type of color wheel that you have, it could either be one with a gold bearing or one with a silver bearing, just identify which one is the one you have, and you'll be goo to go

This sounds like the most common thing that fails on projection TV's, regardless of the brand. The convergence circuit has two, or sometimes three STK IC chips mounted on heat sinks to drive the convergence yokes. They typically last anywhere from 5-10 years, then they fail. It sounds like in your case, the solder joints on the bottom of one of these chips may be failing and some fresh solder will make it go for a while. If it was my set, I would go ahead and replace both STK chips once I took the trouble to take it apart.

Spots on picture screen,color not correct

the picture tube has three color production units (bulbs) red, yellow and blue.....since these three colors can be combined to produce almost any color. as you have specified the red bulb might have damaged due to one of the following reasons.
1.continuous usage
2. keeping your tv in standby mode for a prolonged time.
the only thing you can do is call a technician and get your damaged part replaced.
remember please do not try to disassemble the unit yourself.

The green is taking over all the color on the tv

March 14, 2009

I have the same TV which had the same issue ( green in picture ) - back on 10/2007. I called Sony. They had their technician replace the optical box ( factory defect ). There was no charge for the repair even though TV was out of first year of warranty. Call Sony.
