My mitsubishi rear projection 65 in HD TV has blue and red shadowing overlap. If I turn it off and back on sometimes it goes away but is coming back. I have had the TV for 7 years.
Ok I have tried to converge the colors many times and even rested the convergance to factory settings and the problem still keeps happening what else could i do?

You need to turn down the voltage on all 3 crt's. You have a red one, a blue one and a green one. Slowly adjust the knob down until you don't see the shadow any more. Then adjust your color in the user menu.
Sounds like a convergence ic problem, normaly i tell people to replace the ic's but in your case try to re-solder the pins on the ic first, you may just have some pins broken loose from the board. Locate the stk392 ic's there will be two of them located on a heat sink, unplug the tv and get to the bottom side of the board and re-solder the pins. if this does not work, then replace the ic's
ITS A 2003 HD MODEL,REPAIRING WOULD COST 250.00-350.00 WHICH SEEMS A LOT BETTER THEN BUYING A NEW TV. I RECOMMEND THE HIGHER REPAIR AND GET THE ORIGINAL MITSUBISHI IC'S.
Sounds like a convergence problem. Are you interested in fixing this yourself? If so you will need to know how to solder well and use a meter. I can assist you as much as you need through the process. If you post a picture of what the screen looks like we can know for sure what you have going on. If you call a repairman to fix it he will charge somewhere between $300-$500 to do the repair. Let me know if you need more help!
If the Blue lines are blurs or shadows, then your Convergence IC's are going or gone bad. I have the same TV - it will be 4yrs. old in Dec. Mine started with Blue lines & shadows, then Red, Blue, Green Shadows. This is caused from over heating. The Convergence IC's have to be replaced. I have had 3 TV Repair shops all quote me a price from $350. to $400. to repair. They all said 4 years is the usual life time for these IC's. Replace the STK932-110amps with STK394-250-E or STK392-150 for greater reliability. Use only Original Replacement Parts, there are some cheaper but won't last and can't take the heat. If you are a "do-it-yourselfer" here is a link with the directions and pics. http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm Good Luck!
1. THE SYMPTOM IS BRIGHTER IMAGE ON THE SIDES AND DARKER IN THE MIDDLE. THE PROBLEM CAN BE WITH RED BLUE AND/OR GREEN. CHECK FOR PROPER CONNECTIONS TO THE "DAG COATING AND CONNECTIONS TO PIN 9 ON THE SOCKET OF THE AFFECTED CRT. MAKE SURE THESE GROUND POINTS ARE COMMON WITH CHASSIS GROUND
I have the same problem. Overlaping Blue and Red?
How do i fix this issue?
