However when I press "start", nothing happens and the platter won't spin when ... the arm towards the record without pressing the "start" button. ... SL 7, SL-10... and / or any of the fully automatic Technics turntables using optical record detection......etc Marantz 6300 question...

Hi, remove the platter and check the state of the idler wheel. Is it in good condition? Doe's it spin freely? The cause of the problem should reveal itself. Keep em spinnin, John. Stylus City

What does it do?

As the turntable was hit hard then an internal inspection should be done to look for signs of phyical damage. It could be anything from broken parts to bad soldering or a crack on the PC board. I rather suspect it should be obvious what got damaged when you look inside.

Hi,Dead as in no power up or dead as in the turntable will not spin?? If the turntable isn't spinning check and see if you have a direct drive or belt driven.Getting back to your turntable, if it is belt driven your belt may have become dried rotted. replacements are available at

elexatelier.com/ ,

Have a nice day..

My Marantz 6110 wasn't working right. I had it repaired at a stereo store. They told me the grease was old and had hardened which made it difficult to operate the way it was supposed to. They cleaned it and used new grease. It's been working great for the last 10 years. I hope this helps.

On my Crosley there is a switch on the back for either Phono or Aux In. Make sure it is set to Phono or the turntable won't spin

HI. This will be the cause of a weak motor(winding failure). I recommend to have the turntable motor replaced asap. Once replaced, the table will turn properly.

Defective control PC board. take in for service

Check the small signal transistors BC338 and BC328, they're under the transport mech and will be near where the spindle motor plugs in to the PCB.
One of the transistors acts as a brake which momentarily puts the motor in reverse polarity to stop the CD rotating during 'stop' or 'open tray' modes. The reason the CD is spinning backwards is that the transistor which drives the spindle motor forwards during playback is faulty and is triggering the braking transistor hence spinning backwards.
The transistors should be 'BC328-25' / 'BC338-25' (25v)
Replace these and all should be well.

Hope this helps
