Default Sony Preamp Remote Control Not Working

Get the remote control properly tested to determine if the fault is in
the remote sensing circuitry in the preamp, or is in the remote
itself.

If the remote is defective, then it can be opened and troubleshooted.
If it needs propriotory parts, you can contact the Sony parts
department to purchase the necessary parts. Most of the time, these
remotes are considered disposable, they do not sell the parts, and
they will tell you to buy new one only.

If the fault is in the preamp, the tech can use a scope to trace
through the remote data signal path from the sensor to the uPC.

Many times the sensor module can go bad, a component along the path
may have failed, or it may be a simple cold solder connection on the
board.

There are not always easy answers...

I have a Sony preamplifier, TA-E77ESD. I put new batteries in the
remote control and it doesn't do anything. The batteries all work.
No problem with the preamp and the remote did work a while back when I
removed the batteries (not the same ones).

Any ideas on a solution? Thanks for any info.
