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....
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. Power light will blink. TV may also make a chirping noise.
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.
Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected
That is basically an easy repair its on of the video uotputs on the green, red, or blue crt circuits thats bad or IC309 on the A board. I would recomend getting the service manual for your set to be able to pinpoint which Ic is actually at fault. I can post a link where you can get the manual and they will provide free step by step support to help you diagnose the problem and help locating replacement parts. Thats a free service they provide when you purchase the manual that they will email to you. If you want the manual let me know.
you might wanna look into the "flicker issue" with your set...If you've had it for a while a could be that it's just worsened over time and developed into a voltage leak. I have the same set and it went undetected for a couple of years due to poor quality cable signal..once I went to a clear signal (ie. directv) the issue was very noticeable, but by that time it had progressed. Eventually one of your guns will fail and the set will stop working all together (mine did just under 4yrs from purchase) and unless you have Sears warranty that WILL try to stick it to you. TRUST ME!!! Good luck.
