Hi everybody here.
I would need some help to fix my Technics SL Q33.
Everythings works properly but the Leds circuit for size detection won't.
After some researches and attempts to clean and check every leds inside the mecanism, and under the plater, it seems that the turntable doesn't receive any data from the infrared Leds circuit that is used to check disc présence and sizes.
All auto functions performs well, and start stop will just work as it should. Manual start also rotates the platter as soon as I move the arm.
However, if I place a 7 inches disc on the platter the arm just always set down on the 12 inches edge.
infrared sensors under the arm are 3 Ok (they emit visible red light when I set the turntable on, and the red light stops on the 3 together when I set off)
Nothing visible on the prisms under the platter.
The rubber mat is OEM. ( with the holes)
Everything works very well and auto fonctions are Ok, but size detection isn't.
Please help.
