Hi there,
I have a garage door opener named "Liftboy SMD 3200" which was
installed into my garage back in 1990 (in Germany). I couldn´t get any
information about this garage door opener on the net. The motor
control PCB of it just failed this week. I suspect either any capacity
or the voltage regulator to be the culprit. Does anyone know the
manufacturer of the PCB shown under

Unfortunately, the 40-pin PIC´s type isn´t readable under the sticker
at all ´cause its surface seems to have been scratched off under the
sticker by the manufacturer of the PCB. Yagh. Which PIC is it supposed
to be? There is a Quartz which reads "4.000 SUNNY 7624".
Moreover, the same applies to the 16-pin IC: It´s surface seems to
have been treated by the manufacturer of the PCB, i.e. the exact type
has been completely scratched off on purpose as well. :( Is there any
way to find out which IC it might be?
Please advise.
TIA,
Joachim
