Question about Toshiba TN50X81 50" Rear Projection Television
I have a Toshiba Projection TV that I purchased new in December 1999. Last week the "Red" convergence went out of wack, and when I checked in the manual today for how to address, I found that I was unable to do make any corrections.
I am a Service Manager for a Industrial Packaging Distributor, and I feel confident that I can make the necessary repairs if I can identify the convergence board and the IC's that may need replaced.
I would welcome any information and coaching you may suggest, so I can consider making this repair.
The TV has been sitting in the same location for about 8 years, so no recent moves or banging around.
When we contacted a local Toshiba Service center, they notified my wife that the repair cost would be about $400+ to replace or repair the convergence board.
I tried to adjust the red convergence using the TV controls, but I was unable to do so.
Thanks in advance for you help...or solutions for further testing.
Replace the convergence IC's - P/N STK192-110 with part STK192-150 or 180. Then you can go back in and make the detailed convergence settings and get your picture back in alignement. Also check the flame-resistant resistors around the ICs to make sure that none of them have opened up.
