Default Can this be salvaged?

It's a long story but I recently purchased a faulty sub because I needed the 7" driver.
I got mines so I'm extremely happy.

What remains is a 5.1 190w plate amp and toroidal transformer. There are three boards connected to the back plate. The top board is the amp. The middle board is connected to all the inputs: Analogue RCA, Optical, Coaxial. The bottom board is connected to the outputs.

There is a 12 pin connector which runs from the middle board to the infra-red sensor on the front of the cabinet. I'm guessing all pre-amp function including including input source and power on/off were handled via the remote.


The original sin off the sub was that the infra-red sensor was toast. Is there any way that I can short pins to provide (1) Power on. (2) Analogue input. (3) Max volume.

I know nothing about electronics but live my life through a set of guidelines. Guideline #174 clearly states: the more fuses inside a piece of electronic equipment, the more the manufacturers thought the product worth protecting.

If it can't be salvaged in its entirety I know that some parts may be of value to enthusiasts more capable than me. I'm in the UK - any parts you want hit me up.

Why not just fix it? Is the sensor for remote control? If so, and if you can get to it to replace it, I'm sure a suitable replcement part should be available.

There is no remote control. There is no sensor. I have salvaged the part I needed. If I can make it functional at no cost to me I will give it to somebody deserving.

Two previous contradicting statements suggest this last quote is correct.

If you believe those statements are contradictory your English comprehension skills are even worse than my understanding of electronics. Maybe leave the smart comments to smart people?

OK...so you have a plate amp from a powered sub, the IR sensor is bad/missing, you have no remote control, and you want to figure out how to power it up...do I have it right?
If so, there may be a relay the remote sensor module would activate to turn the unit on. If that's the case it should be just a matter of substituting a switch for the relay....assuming there aren't other things like a mute function involved.
