Yes,tv screen have R,G,B colors lines mis alingnments,have colors shaded pictures or 3D pictures look aike?Tv have a problems known as convergence pictures problems.The tv convergence board it is dead.This convergence board must require replacement of 2 STK convergence ICS and some or all of it resistors too.Fixed the tv convergence board to solved the tv convergence pictures problems.U have some mechanical skills like take things aparts and putting it back together again?Yes,try website like Tvrepairworld.com to buy a whole refurbish tv convergence board for the replacement.The DLP tvs brands names Samsung and Akai used the same tv convergence board.Or tries those tvs shops will cost u like $300-$350 for parts and labors.
Very expensive repair must be replacement of the light projection engine block to sloved this problems.This problems are happening to many tvs brand 50-70 up DLP projection tvs like Samsung,Toshiba,Misubishi,Sony because they all put in the same problems IC design on their projection tvs on their light projection engine block.Talk to Samsung,might get some help with the repair.
You are going to need service code for entering into Techician realining of convergence CK all small ohm resistors near ICs 1.5 2.7 3.9 ect.. I cannot find Service code, list Need Service code to enter Convergence Pattern.Will try to find my List of service code for all TVs and list them but untill then Try Listing Looking for service Code for Toshiba.
LOOK for 3 parts that start with STK (BLACK THINGS THE SIZE OF A MATCHBOOK) then replace all 3 (ebay) also look for some green coils that may be burned. If you SEE THE STK's then your in luck, as 95% of them are bad.. Please rate!
The speed of the color wheel needs to adjusted or the CCA values. Both are found in the service menu . If you paid a company to fix the TV, call them and tell them that they forgot to perform these alignments. If you did the repair yourself, you'll have to call around for a price to have a Samsung service center perform these adjustments. I don't recommend consumers access the service menus of modern TVs because one wrong button push and you may cause irrepairable changes to the TV's proper operation.
I believe it is mute-1-8-3 to enter the service mode, HOWEVER, I have also read that until the convergence problem is repaired, i.e. - depending on the configuration, either 2 individual IC's located on the lower board with 'playing card' size heat sinks or a simple replacmenet convergence board, adjusting the convergence through the service mode is comparable to "ripping the transmission out of your car to fix a flat tire". I myself have not gone into the service mode since I am still waiting for the replacement IC's - I get to do a component level repair.
