Does anyone have experience of this type of issue with Beorgam 1202 / 1203?

My latest beogram 1202 project. When player has been unplugged from electric socket and you plug it and press 'lift' button. the record starts to rotate, but tonearm does not move into record. it is just rotating, and does react when lift button is pressed again (to stop it). also moving tonearm into record center does not stop it. Only way to stop it is to unplug it from electric socket.
After unplugging it, when I try again. it works like it should. (press lift button, record rotates, tonearm moves on 1st track, audio good, tonearm returns after last track). and the player works well if it is used constantly (means having not more than 1-2 days break).  If i dont use it for 2-3 days it shows the same problem. turns on, but does not react to any button or tonearm position. 

is it mechanical or electric issue? I have no idea. I have checked the voltage to be 220V. also tried 110V.
