I'm having trouble with a stairmaster 4000pt. The display

Customer Question

Hi, I'm having trouble with a stairmaster 4000pt. The display lights up but the buttons are unresponsive. The LED display just has bands of red led lights going horizontally across it, not moving. It looks like the DC plug going into the stairmaster was reversed. Could this be a load resistor or alternator issue?
JA: What's the make/model of your device? How old is it?

JA: How long has this been going on? What troubleshooting have you tried?
Customer: It was working fine until today. I've tried plugging it in for a while, unplugging it for a while. So far no change.
JA: Anything else you want the equipment expert to know before I connect you?
Customer: That's all the information I have.

Hi, Im sorry to hear that. How old is your Stairmaster 4000pt?

Also will it respond to any button presses at all?

Thank you

Sincerely

None of the buttons work, again the display is lit up and I'm not sure how old the machine is. Several years I would think. It all worked fine until trying to plug it in today. The only thing I can think of is that the DC plug almost went in the wrong way into the machine. The display is lit up with red leds across it but they're not moving.

Hi, that shouldn't cause this problem, but anyway, the main console needs to be replaced in order to fix this one.

Its easy to do and there is no soldering or special skills required;-)

I will assist you at no cost additional as well.
