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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from
TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

I have a Canon printer. Whenever pictures or text gets a double or blurry image I open the printer solutions menu. It sounds as though there is a problem with inkjet alignment. By clicking the realignment button the printer will automatically realign the jets. I usually test the alignment by printing a page from that program. All the line segments should line up.

'Shadows' behind all texts and images on the screen


[u][b]LCD Monitor Shadow Effect[/b][/u]
This problem is best described as the LCD monitor "Shadow Effect".
The solution to this very simple. No software or hard ware changes required.
The cables that are connected to the LCD monitors are causing the problem. Its also called as electromagnetic noise or electrical noise.
[u][b]Solution: [/b][/u]Keep the two cables - (power cable and moitor display cable), that are connected to the LCD monitor as far away as possible with each other and also away from other electrical cables.
Thats it. Your shadow effect is fixed.
Thank you.
