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.
Ur tv have a problems known as a convergence problems,it dead.The tv convergence board require changes 2 STK convergence ICS and some or all it resistors to solved convergence problems.The shop,will cost u $300-350 for parts and labors.
When you presss menu and then select settings is the auto convergence and convergence options still there or have they disappeared/ Let me know and I will assist you with the problem.
go into the menu find convergence
some models have auto convergence
if you have the option to manual adjust convergence adjust red and blue DO NOT move green
Look in menu go to setup see if you have convergence listed on menu if not you have open fuse FL231, located next to flyback on right side there is 3 in aroll small brown looking caps middle one is it FL231.
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.
