Beogram 4000 needle lifting

I can’t say I’ve ever seen that particular behavior. Have you replaced all of the electrolytic caps? These can be the cause of intermittent issues and is required for a Beogram of this age.
I have found a number of these random intermittent faults have been caused by the switches feeding the logic gates within the control panel, the logic chips are very reliable and seldom, if ever fail....the switches feeding the gates however are very susceptible to fail...typically arc and corrosion, and also bending over time...if a leaf type switch is left stood in one position for a long time it will loose some of its elasticity. The switch that controls the lower current to the magnetic coil is one such switch, if this is not clean and fully functional it could cause the issue you describe, also clean and inspect the control panel switches....have a read of the training notes donated by Solderon in the manuals section of the products area.....they are very informative.
Good luck!

I have fixed it! I looked at some older BeoWorld posts and found this thread (/forum/beogram/4002-tonearm-lifts#post-2223218) about a Beogram 4002 with similar intermittent symptoms. I exchanged 0TR4 and the Beogram has not shown the error since. Whilst I was at it, I also ordered the Main Capacitor Array with Integrated Efficient 24V Power Supply from Beolover and some new belts and did some further maintenance, and the Beogram has been running lovely since. Thank you for your help guys :)
