Question about Mitsubishi WS-65809 65" Rear Projection Television
I have the same tv. I had the same problems. It started with the lettering on top and bottom showing the different colors, it progressed to the top and bottom being pulled into the middle, all this would go away, but come back, sometimes it would be when the tv is cold and at others it would do it when it is hot. It would turn on ok but then act up, it would turn on with the problem, then go away, so there was no reason for it yet there it was. It progressed to the point that it would also have lines snaking across the screen, very long lines, moving in every direction. till finally the tv would not turn on at all one day.
It produced a code of 22 when the diagnosis was engaged. (code 22= short protection), I checked the fuses(fa95a and fa94a) they were open, which ment the IC's were shorted. The horizontal and vertical deflection IC, both of them. (watch for the look in your friends faces when you you respond to there question of "What did you do to fix it" and you respond with" I replaced the Vertical and horizontal deflextion IC" it's priceless).
So you need two deflection IC's, its important to know that they are the same part and interchangable, the rest of the tv makes them do their specific job.
They can be obtained here: http://www.bdent.com/ There 16 bucks each, plus shipping and handling.
The fuses are not avialble from BDent, go figure, they would have to be obtained from some other source, I got mine from: http://www.mcmelectronics.com The fuses are not an exact replacement, but all fuses do is protect circuitry I was comfortable using a non identical part, the fuse is rated as a 5 amp fuse. It had a 250v rating also. the voltage in this case is not an issue.
If you have any experance in circuit board soldering then you can do the job. The circuit board they're on is easy to tell, its the one in the middle, It has a massive aluminuim heat sink with the IC's mounted onto them, the board has to come out, (the heat sink is mounted to the tv,thru the board), so you have to remove the heat sink seperatlly. The board has other heavy components, so care has to be used to hold and handle the board (handle it like you would a newborn, it is after all your baby!) the board is not strong enough to support the components on its own.
the total cost for me to fix my tv was under 70 bucks and i also ordered the servive manual, My training is in Avionics, but if you have some soldering experiance or a friend who has some, a friend who does a/c tech , or model airplane as a hobby he can help, just watch those a/c techs they can use too much force sometimes. If your not able to do the job it's worth paying someone to do it or parts of it with or for you. If you take the board out expect to put it back. It's still a great tv and to have it up and runing, well I don't have to tell you how it feels. Replacing it is not an option, it cost me 2800. and that was only 6 years ago, when i opened the tv it was in great shape inside, no leakage from the guns, no excess dust, just looked new.
If you live in any state surrounding Indiana I'll do it for 500.00. from here to ny city-700.00.

As was stated by Irish, sounds like convergence IC's need replaced

Good Day, rockinanreel;
Most TV repair shops charge somewhere between $450.00 TO $700.00 and more. It will depend on your location an type of shop. Stay with an authorized service center and ask before hand what the charge for the repair of changing the convergence IC's.
Good Luck, big IRISH.
