Broken Mounting bracket Toshiba TN55X81

The mounting bracket supporting the board PB8923 in a Toshiba TN55X81is broken. I thought of trying to epoxy but would rather have a new bracket if they can be purchased seperatedly. I'm having trouble locating a supplier.

I have a TN55x81. the picture will just stop working (goes black). I will shut it off for about 5 minutes and then it will work fine. Some times for 2-3 days and other times just 10-15 minutes. Any ideas??


Intermittent problems on this type of TV are often because of cracked solder joints on the circuit board. They can be hard to see. When the TV gets warm, parts on the board expand and move by tiny amounts, sometimes with the right amount of expansion or vibration from the speakers, the broken solder joint looses connection and the unit shuts down. When things cool-off, the contact can be made again all by itself and everything fine until it happens again. Given the random nature of your problem, this is a suspected problem. Often it is the solder around the lead of a large component which is mounted to a heatsink.

It shouldn't be the convergence chips. You may have blown a pico fuse on the power board.
You should be able to safely remove the convergence IC's and try the tv without them as they only do image correction.

Replace the IC's with STK 392-110T.
Toshiba has a Service Bulletin on this problem.

Toshiba TN55X81 Wont turn on but I hear clicking


Pull the three connectors to the yokes on the convergence board. If the set powers up, it's a good chance the STK392-110's need to be replaced. I fixed one today, and it has been running for 6 hours now.

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:
