Good Luck!

Over temperature protection, is it well ventilated?

It is not the socket. If the bulb is installed correctly, there is a starter on the ballast that needs to be replaced.

I was able to find you a PDF Manual for the tanning bed model you listed, the key to looking for it online was to enter Wolff Sunvision Tanning bed......without the Wolff part it didn't come up.
Hope this helps and good luck!

REd + Black - and white common.

Have a trained technician to: Check main breaker, check that bed is getting power to it, check for bad fuse on back of bed, check for burned out wiring inside of bed at main relay, check that the timer is good.

Why do you need a diagram? Tell me what the bed is doing or not doing. I may be able to help.
