Toshiba Tn55x81 frequent convergence problems especially blue/ red double vision. Plus picture get very blurry at times.


If this only occurs occassionally, it suggests that there are bad connections at the convergence ICs rather than defective ICs. If you can solder, try resoldering the pins on the ICs. That may resolve the problem. These ICs are large, black and attached to a heatsink. They will be marked STKxxx.
Keep us posted.

TN55X81 Rear Projection color separation - convergence problem


You shouldn't need to do a board replacement, all you should need to do is manually tune the convergence.

You can do this with the built-in user tool, but there's also a far more powerful set of options in the service mode. To save you the trouble (I advise doing a LOT of reading before attempting any of this) here's a solid set of various tutorials based on what form of "separation" you have occurring:

Blue convergence IC is bad! Blue CRT OK!

Required for repair---pull chassis,replace STK392-110 X 2.

Re-assemble,adjust convergence as needed.
