Hi, I am trying to repair the main board in the Beogram 40002.
I know the rest of the unit functions properly.
lights function on tonearm and below tonearm.
Slow <> both work
Issues are as follows:
>> only works when I keep it pressed
<< only works when I keep it pressed
^ up and down don’t work
At rest SO - pressing 33 platter (motor) turns
When unit is engaged both 33 button and 45 function - and Chang speed of motor
Automatic drop doesn’t engage.
I have looked at the schematics quite a bit
Not sure if it is a problem with the motor control circuit as the buttons do engage the motors and DC readings and are same as the working board when tested. Could it be electronic switch circuit and/ or solenoid circuit? Or a transistor or diode near the buttons.
