Could this be true, or am I getting the run around.?

Could this be true, or am I getting the run around.? Sumiko is telling me that the on/off and speed box issues I am having with my Classic SB TT are environmental. They say static? I need some feedback. 

I sent a Pro-Ject Classic SB to Sumiko to be looked at because the motor would not respond correctly to the speed control button .  

  1. Sometimes I would go to turn off the TT to flip over an album and the motor would keep running no matter how long or how many times I did the long press. 

  1. Sometimes times I would go to start the motor and nothing would happen but the indicator light would go from flashing to a solid blue as though the machine was running and up to speed.  

  1. One time I tried to turn the machine off and all it did was cycle back and forth between 33 and 45.  

  1. Another incident I was playing an album and half way though the motor just stopped dead. But not according to the blue light. The solid blue light was indicating that the motor was on and up to speed. 

Can static cause 5 different speed control issues? Particularly nu# 3, where trying to turn the TT off resulted in a 33 to 45 back and forth. I have a normal house with a humidifier installed on my furnace. They want to return the machine as is. Any advice?

These links will show you examples of the failures.

static can potentially damage lo-voltage capacitors which I’m sure there are on starting motor circuit. blown capacitors may cause other issues so troubleshooting just a static can turn out to be a nightmare, but within the turntable start-up circuit, there aren’t many capacitors to replace nor any other circuit elements to check/repair and replace.

getting it unrepaired or untouched by techs and sent back isn’t new today and pretty usual, but it wasn’t normal few years back tho.

I'm literally freaking out if I have to bring my truck to repair facility simply because of trusting issues I have now that I didn't have several years back. now all repairs are done my me and only me.

BillWojo, tube amps as pretty much other equipment has chokes to the ground, not sure if this TT has it. That's basic protection and it works.
