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
