Check the convergence settings if necessary, try to check the bulb cause sometimes is getting weak. If you want to replace the bulb don't forget to reset the lamp hour meter. Let me know your feedback. Good day and God bless. Hope it helps.
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.
Tv have a problems known as a convergence problems,it dead.The colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.The tv convergence board must have these parts replaced to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
The tv have a problems known as a convergence problems,it dead.The tv have colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors.These parts on the tv convergence board are dead,must be replaced on the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
Flash Focus magic button no longer work.The tv have a problems known as a convergence problems,it dead.Tv colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures problems.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts,must be replaced on the tv convergence board to solved the tv convergence picture problems.The shop,will cost $300-350 for parts and labors.
This problems very common on DLP Tvs.This problems known as a convergence problems,it dead.Colors lines R,G,B mis alignment,have colors shadows or 3D pictures.The tv convergence board is dead.Require to be replaced on the tv convergence board 2 STK convergence ICS and some or all it resistors to solved the tv convergence board problems,to solved tv convergence picture problems.The shop,will cost about $300-350 for parts and labors.
No.This problems it not the projection lamp problems.Yes,this problems is the tv convergence board problems,it dead.The tv convergence board the 2 STK covergence ICS and some or all it resistors are dead.These parts,must be replaced on the tv convergence board to solved the convergence problems.U have tools like a soldering iron,desordering pump,know basic electronic and soldering?Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.Or the shop will cost u $300-350 for parts and labors.
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks! See link for more detail http://www.ehow.com/how_4575598_yourself-projection-tv-repair-convergence.html
The are controls on the inside of the tv above the circuit boards for focus and to turn up intensity of the projector lamps (red, green, and blu). If you turn it up too far all three projector lamps kick off. If this happens, power off the set and turn down the lamp that you turned up. Power it back on and slowly turn the projector lamp up until the picture looks OK. You have to take off the panel on back of set to get to the controls.
