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.

I told them that when I turn over albums I never get a shock,  so they said it was the records. 

carlsbad, true on that. This is b an sporadic problem. 6 times in 4 months. That is way I sent them 4 video's  of the controls failing. 

 

Sounds like the run around to me. Give them a chance to fix/replace it and if the problem still persist, demand a refund.

 

@czarivey it's IC chips that static kills, they typically operate at 3.3 or 5VDC and a static discharge will fry them. Most other parts are pretty hardy. I've never heard of say a tube amp being damaged by static.

If it does have static sensitive parts, why they heck didn’t they isolate / protect those parts properly? Computers, TVs are chock full of sensitive parts. Literally no other consumer product has this problem. 

No problems with my SB, or my Music Hall mmf-7.3..both tables use same motor. You got a bum motor, just replace it. You can buy them separately on line...sometimes a better option rather than all the red tape. This could happen with any brand turntable, not exclusive to a pro-ject. Also, the buttons on the motor are rubberized plastic, so not certain how it can be considered a static issue. You are touching the buttons and not the metal parts of motor. Jmo
