You need a pulse output from the photo-cell, Martins advice below is a good place to start....adjusting the lamps position in the lamp holder may work for you....

Also - check the lamps position in relation to the lens system.
It needs to sit right in the sweet spot.

0tr4 unsolded and measured... is fine! Got to look again to the electric scheme.

Another day, another problem.

Hi to all.

For other user´s i wright here the solutions that i found to each problem´s.

Beogram #1

• DC Motor Stop reward and when testing stop moving at all

Solution - Substituted  1TR28; 1TR29; (Forward) 1TR30; 1TR31 (Reward)

• Solenoid stop working

Solution - Substituted  1TR10; 1TR11, Still not working, but after my Beogram#2 acuse same problem, days later, i found the final solution... Just change 5V 50ma lamp that blew solve the problem on both Beogram´s, Solenoid circuit begin´s to work again 😉

Beogram #2 (that i start restoration)

• Not detecting LP Size

Photosensor just cracked, i substitute with one Osram Photodiode SFH206K TO92

Now i will get my Beogram #2 to a specialized store to final adjust´s, because as i said i´m not for electronic and don´t have the necessary measure tools. 
Thank´s to all that try to help and that post during the years is problem´s and solution´s in this Forum.
