Re: 43H71

If you're talking about the STK392-100 convergence amps, the repair manual is not a great deal of help.

Here are two websites I found helpful:

Good luck.

I have a 43h71 Toshiba that does not have a picture. The red power light is flashing. Any idea what this means?


Most manufacturers today have taken advantage of the diagnostics available when circuits fail. Your flashing light indicates generally where the problem is. This is disigned to help us technicians find the problem easier and faster. You did not mention the number of blinks. Toshiba is secretive with their error codes. You would need to buy a service manual from to obtain them. Cost is about $16.00 US for a download. This would provide the information that you need.

Thanks for using FixYa and for the great rating. Please consider a testimonial.

Toshiba 43H71 - remote sensor not working

The sensor is not the only fault that can cause the remote control to not work. The sensor is only one part of the circuits involved.

Between the sensor, there may be buffer amplifier stage, and then there is the main uPC.

What we do is send a remote IR data signal to the sensor, and on the circuit board in the set I follow the data signal along its path using a scope in reference to the service diagrams to see where the data loss is.

Personaly, I would not blindly buy a new sensor based on a guess without doing the proper tests.
