Proceed AMP5 in protective mode


My Proceed AMP5 has a flashing standby light. According to the manual, this means the amp has gone into protective mode. I shut it on and off but no joy. Checked speaker wires and no shorts. The amp is plugged into a Monster power bar. No apparent power surges or lighting etc.

Doesn't seem to be a reset button outside like most amps have? The manual suggests calling tech support. (What support from HK!?!?!)

Has anyone had a similar problem. Does anyone know if there is a reset switch inside? Does HK still repair Proceed gear?

THanks for any info or suggestions.

I too have an Amp 5 with identical problems .

I did the same thing (removed all cabling), it will power up without going into protection mode but as soon as I reinstall the cabling , it will not go into a standby mode .

Fearing it was speaker or cabling shorts I threw in a Rotel 5 channel amp , no problem . Tried other power cords , removed line conditioner ...no go .

This took place after doing it a couple of times , once during a movie and once left idling in standby . I was able to restart it those 2 previous times by pulling the power cord and waiting a few minutes ( like a reboot)

I took it to the Levinson shop yesterday and the tech was able to start it with no load . We did not get into it any further as he's quite busy but promised he would call Harman to see if this was a common problem . The serial number is 1011.

Short of paying 800 repairs for an amp worth about 1800 on todays market , I would love to hear of a remedy that does not require transporting this 110 lb beast and in turn if I hear of a solution , I would be more than happy to share it.

It'd be really interesting to hear from others , especially if this is an ongoing problem .

Hopefully there is a cure without major freight and repair costs . It's too bad as the Proceed gear sounds wonderful .
This is a follow up with a great ending .

After taking the amp to my local Levinson dealer , the tech pulled the control board and reinstalled . The problem was found to be a cold solder connection .

It's been home a month now and working 100%
