Monster Power HTPS 7000 Error Codes

[BHachmeister]

My Monster Power HTPS 7000 normally displays the input a/c voltage, like VOLTS 120. But occasionally it displays what I assume are error codes: 333..124 or 444..124 It continues to function OK (or at least I assume it does) while it displays those codes. The codes display for a few seconds and then it goes back to displaying the voltage.

Does anyone know what these codes mean?

I found the owner's manual on-line but no mention of error codes in it.

I've worked on a couple Monster power conditioners. They're nice units. This one is very nice. And amazingly enough, there is schematics for it!

Yes, my manual doesn't mention error codes. Rather annoying, no ... ?

Thank you for the schematic! I haven't checked around, but I wonder who would be able to work on this if and when the time comes ... does anyone know of a good tech in the Rockford, IL area?
