This unit takes the form of a grip and enclosure for a PCB control board and motor/gear drives.
One of the lenses does not operate. From the unit there eminates a faint sour burned cork smell reminiscent of burned out components. I have had a good web search and not been able to find any circuit info for the internal PCB.
Does anyone have any info on the controller PCB which bears the number 110B6644691.
This specimen appears to have had work done in the past. Some of the soldering is very dull, possibly low lead which has been known to cause problems around the time it was introduced.
Some connector joints have been reworked with leaded solder. I could go blindly through and rework all the joints with leaded solder. I may introduce more faults than I solve. Despite its low value in today's market I wold be better served by approaching it systematically. The chances of a casade failure through the entire thing may be good however I have struck it lucky in the past when some parts failed into open circuit.
Any advice will be appreciated.
