I have the ability to repair this thing. The only trouble is that the
unknown proprietary chips used were never made generally available.

Even Silent Knight won't repair this thing anymore.

I had a SK9800 CS receiver with a bad LCD screen. Honeywell required me
to send it in for a minimum of $1200 repair cost. I contacted a supplier
of LCD displays online, and sent in photos of the bad part. I ended up
spending $40 + shipping for the replacement LCD module.

It's not that I am cheap...ok, ok, yes I am... :)
