What a sign of the times.
Years ago, when an electronic device went bad, since everything used
discreet components, mostly all you had to do was take a VOM and
figure out which component was fried, and replace it. And if you had a
working unit you could compare component readings from one unit to the
other to find the bad component. You could even repair TV sets that
way, if you had the patience to do it. Occasionally you'd have to buy
a set of SAMS schematics and resort to a oscilliscope to trace some
signals, but not that often. And what would we have done without the
Tube Testers down at the drug store?
It's amazing that all that aquired knowledge is so useless now.
Repair nowdays consists of .... If it don't work ..... throw it
away and get a new one.
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...
