Problem with Beogram 4002 Type 5521

[Paul Mac]

I purchased this turntable, which worked, but the belt wasn’t original. While waiting to buy it, I decided to lubricate the threaded shaft and the rear steel shaft of the shifting mechanism. After that, every time I press the Start key, it doesn’t stay on, and therefore the turntable doesn’t work. If I move the carriage by hand toward the center of the turntable, it works. When I press the Stop key, the carriage moves to the rest position, and I can no longer get it to work properly. Thank you very much!

Its unlikely that lubricating the carriage drive screw and associated wheel would cause the problems you describe, I would take a close look at the carriage position sensor and ensure it hasn’t become detached or damaged..see the attached blog from the beolover….his issue was different to yours but i suspect it could be related…send some pics of your unit for us to view

First of all, thank you for your response. The IR diode has the correct voltage, 1.1 volts, and the receiver has 5 volts at the collector and 0.7 volts at the output.

I unsoldered the IR diode and tested it with my cell phone’s camera, and it works. And the receiver didn’t move at all (I think).
