Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

How do i get my computer out of the resolution mode?


Apparently the monitor screen resolution setting is not correct. Screen resolution stays up until it is corrected.

Either the setting is off in Windows, or you have been changing the monitor settings, with the monitor.

WinXP:

Right-click on an empty area of your desktop screen.
Left-click on Properties at the bottom of the list.
Left-click on the Settings tab.
Go down to where it states Screen Resolution.

What is the pixel setting? For example mine states 1600 x 900 pixels.
I am running dual monitors, and this is the correct screen resolution for the Primary monitor.

If it wasn't I would Left-click on the Slider, hold the left mouse button down, and slide the Slider to the correct native resolution.

(Under Screen Resolution is a line. To the left it states - Less
To the right of the line it states - More
The Slider is the rectangular down arrow on the line )

ALSO;
Under the Color quality heading, make sure in the box under it, that it states - Highest (32 bit)
IF not, left-click on the blue down arrow to the right.
Then left-click right on - Highest (32 bit)

How to know what is the native resolution for your monitor?
Look at the manufacturer name, and the model number on the back.
Type this information in your browser search bar, then click on the search icon.

Look for Specifications.

If you changed the screen resolution settings with the monitor, press the Menu button. The screen should go off.

ALSO, with a new monitor there is an Installation CD Disk, provided with it.
This disk MUST be used. It has the drivers for the monitor on it.

[ Drivers: Small pieces of software that allow the Operating System to 'communicate' with a device.

The monitor is a Device.
Windows XP, and Windows 7 are two examples of an O/S.
Operating System ]

If you have Vista or Windows 7, post in a Comment.
For additional questions please post in a Comment.

My KDS-55A2000 displays some shades of blue as green. It's not just one area of the screen but the entire screen. Flesh tones can be adjusted to look pretty normal but scenes with light blue sky look...


Your t con board is responsible for the image on your screen. Your colors are all there but they are f---ed up in certain scenarios.

That is the only board on your set that be causing this anomaly.

Bright yellow


I can't imagine a setting that would cause this - It sound more like some sort of fault with the projector's blue LCD panel. (The image is created from a mix of red, green and blue light. If you loose the blue, everything will look yellow.)

Is it capable of showing any shades of blue?

Using any graphics or photo-editing software, create a solid blue image (R=0, G=0, B=255 in your colour settings) and if possible, display this full-screen. Is there any output from the projector at all when you do?

If not, it sounds like it need a professional repair.
