Technics SL-P 1200

[NoBit]

Hello

Yhis is my first post on DIY, wow!

So, I'm here to ask gently help on a little problem on my cd player SL-P 1200 that actually I can't solve (I'm not a skilled technician).

Normally when powering up the player the laser pickup is moved to te center of the cd (starting position) even if a cd is not present except in my player... Everithing else works perfectly so if I put manually the laser in start position it reads the TOC and start playing, if this is not done the disk start to rotate and the pickup start to move but to the exernal position...

I have the schematic too

If needed I can publish here.

Thanks a lot forever
