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.
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.
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.
Thats a common problem that can usually be repaired by installing the RCA repair kit called ITC222 and ITC222A convergence option missing repair kit which is available from www.tvrepairworld.com
The kit contains the parts and the CD with instructions.
This is a convergence problem that will continue to get worse. I repaired a few of these recently and found that the main problem was poor/broken solder connections at the flyback transformer. Please note that there are potentially dangerous high voltages present inside the set even when unplugged.
That being said, the flyback needs to be resoldered and the pico fuses close to it need to be checked and replaced should they be open.
The parts cost for this (even when replacing the 3 pico fuses) should not exceed $10.
YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.
It sounds like you have a convergence amplifier problem. There are many articles on the Internet on how to do this type of repair yourself, but what these articles fail to mention is that if done wrong the chances are your TV will be damaged even more. So I would suggest that if you do not know electronics, for you to take the TV to a repair shop or have a TV technician come to your house to check and recommend a repair strategy for your TV set.
