Tv have a problems known as a convergence problems,it dead.Tv have 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.These parts 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.
This is symptom of convergence output chips failure in rear projection tv, replacement of convergence output chips will fix the problem. Chips/ IC replacement requires soldering work in circuit board, if you are not familiar with electronics stuff fixing an soldering work, call local tv repairman to help you. Thanks.
I have the same problem. I was able to temorarily fix the issue by taking the back cover off and blowing all of the dust out. But this only worked for two days. Now the problem is back. Did you fix the issue with your tv? Thanks.
daveT29 - I had my brightness cranked, too. The picture went dark and off-color after moving the TV from one corner of the living room to another.
After waiting for the TV repairman for about 4 weeks, I "fixed" it myself. Take the front panel off (4 screws, then a black panel) and blow out all the dust. I was afraid to use a swiffer duster because of the static electricity, so i just used with my mouth blowing powers.
