McIntosh MX 132 issue

Hi all,

I would like to appreciate for your time and your advise!

My preamp MX132 is connect with only one amp which is MC7106. They worked pretty well until my little boy messed them up two days ago.

Now I turn MX132 on by remote or the "Stand By/ On" button on front panel. It stay for 2 to 3 seconds with MUTE message at LCD, then it shuts off by itself.

I tried to play around with it and I can make it stay on with "Remote Zone" message at LCD, but remote control cannot control it any more, and NO button on front panel working accept "Stand By / On" button and power switch (to turn it off).

Hopefully, one of you can show me how to fix this issue.

I would like to appreciate for your time and your advise!

Hito.

I agree, unplug the unit and while it unplugged, individually press all the buttons on the face plate.
That will drain any stored capacitence and release any memory lock. Then plug it back in. I have owned a number of McIntosh pre-pros including the MX132 and this has always worked for me.

Unplug the power for a couple of hours and remove the fuse if there is one.

Also I would add to Cnote's response, disconnect all your connectors and repeat my suggestion of a de-capacitence.
If not give McIntosh a call. One thing that might help is give us an explaination of just what your son did. Did involve water/fluids, sudden impact or shorting of wires??
This may have a direct influence on the solution suggestions.
