McIntosh mp 100 Phone Preamp Problem.... Blinking Red Power Button

Hello all,

So my amp is getting serviced, and it was apparently two things that failed. The power supply, and some sort of small transistor. It is being repaired. 

QUESTION: This seemed to happen when I was simply swapping out a new custom fabricated interconnect. 

Do you think there is an issue with this interconnect? Or was it a fluke? 

Thanks,

Richard

Yes I did try that already, and did again. No effect. The little red led blinks above the standby / on button and that is all...

And I put in a ticket with McIntosh directly. Any ideas? 

Thanks all, wish me luck.

Have you tried this, as explained in the manual:

Reset of Microprocessors
In the unlikely event the controls of the MP100 stop
functioning, the microprocessors can be reset by per-
forming the following:
1. Press and hold in the STANDBY/ON Push-button
until all the Front Panel LEDs start flashing, then
release the STANDBY/ON Push-button.
2. To switch the MP100 back On, press the STAND-
BY/ON Push-button

I thought that might have been the case as well, somehow I caused a short switching interconnects? 

But I am surprised that that could have happened with gear like this...

I bought it used from my brother in law... can I still contact McIntosh? It is only maybe 5-8 years old. 

Any way for me to diagnose? 

Thank you,

Richard

Why not just contact McIntosh?

Unless you would rather take the scenic route, of course.

Could you have possibly shorted something changing interconnects?
