Need help troubleshooting an amplifier.


Hi all,

I need help troubleshooting an amplifier. I've tried googling for some answers but come up short. I'm such a novice I don't really know anything about electrical stuff. 

Here's the problem with my amplifier. It turns on, it gets stuck on stage 5 which could potentially mean a power supply issue or one of the Module inside the amp.

I've checked the DC voltage on the speaker terminal. Black terminal registers -0.05. Red cannot get a reading, stays at 0. 

I've contacted the designer but it takes a very long time to get a response so I'm here seeking you guy's expertise while I wait on the designer.

If it's a power supply issue, what does this mean and is it a huge issue to fix? Any other theory on why my amp is having an error?

Thanks all. I'm just super restless and it's been more than a month without music. Some might understand my agony.

@carlsbad2 Normally it turns on and countdown from 10 to 0. But in this situation it counts to 5 and then get a permanent error.

Based on all the description I can give, that the positive terminal has no voltage. Could it mean a blown fuse on the power supply?

I didn't include make and model because I'm certain it won't change the end result.

The make and model is BMC S1

@mlsstl

The reason I didn’t include my make and model initially was because BMC is an unknown brand. I expected 0 people here to know about its specifics.

I only asked basic eletrical stuffs that would apply to most amplifiers, like DC voltage of the terminals and if the readings were normal, and if this could potentially be a power supply issue.

I'd love to send this amp off for repairs but it's 100 lbs and very uneconomical and would make sense only as a last resort.
