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

Hello all,

 

Appreciate any potential help... I'm a little dismayed... 

I was testing out RCA interconnects on my McIntosh MP 100 preamp, and suddenly the green faceplate starts blinking about every second. After maybe a few minutes of this, just the reg light around the power button blinks about every second. 

 

No more power on! 

 

I looked into the manual, and I didn't find anything that would help. Any suggestions? Did I blow a fuse? Did I somehow kill my McIntosh mp 100 phono preamp?

 

Thanks

Richard

Could you have possibly shorted something changing interconnects?

Why not just contact McIntosh?

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

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

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
