Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from 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....


\012
    \012
  • Screen looks 3D \012
  • Colors don't line up \012
  • One or more colors can't be adjusted when using the convergence menu. \012
  • Screen is bowed or warped. \012
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

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.

Sony kdf60xbr950 Having the same problem with no picture. Green lights blinks first then the red lamp light. My first thought is the lamp. Then I had talked to a tech and he tried to tell me that its the balist or the power supply and likley not the bulb? Has anybody else been throught this and what was the outcome. This is the original bulb with only about 1000-1500 hours on it ? was working fine one day and the next this ?


The problem here with the lamp is it has an average 2,000 hour life--only way for a "tech" to know if it is the problem is to replace it.The ballast is the power supply for the lamp---lamp goes bad a lot more often than the ballast= sounds li ...

Samsung SyncMaster 305T One-half of the screen (the right-hand side) gets dark. It turns black and I can barely read the text in a document. This problem is NOT consistant.

My questions: 1) Where can I find the part number for this bulb and who sells them? 2) Is there another part in the circuit that may be the

On my HD1080 Mitsubishi projection flat screen the picture is bowed on top and bottem and it look as if the projectors themselves are offset, but the picture is clearer as you come toward the center. If I smack the side the picture will sometimes come back into focus. But the picture will soon after go back out of focus and sharp swiggly lines streak across horizonally. How can I fix this problem and how much might it cost.


You have poor contacts and or dry joints. Resoldering on the convergeance panel and powersupply/line timebase board will probably fix it.It should take less than an hour in labour terms. ... Mitsubishi WS-65809 65" Rear Projection Television

I am having the death click problem with my 42PFP5332D/37. When plugged in, all it makes is a rhythmic clicking noise. I pulled the back off and found the clicking noise was a relay # SDT-S-105DMR. There are a pair of them in the big board in the middle of the back. I pulled the covers of the relays and the one on the left is actuating up and down and sparking. Can anyone tell me what the cause is and if there is a reasonable fix for this.
