Technics SL-D2 not working

[El moncho]

good afternoon to all the members of this forum, I am a newbie with desire to fix my turntable Technics SL-D2 which are not working, I do not have much experience in electrical circuit repair, if I can say that you check the transformed and is delivering current to the plate, someone will have any recommendation to continue looking for possible solution ??
Thank you in advance to all who can help

I would suspect the switch contacts to be dirty and/or defective. The switch is activated when the tonearm is moved off of it's rest towards the record. The service manual can be downloaded at VinylEngine.

Thanks Decibel, check both switch and they are good, I do not have much experience with voltage measurement, what do you recommend to check ??
