Yes, I fixed mine. I took a chance and ordered the power output IC from Mouser electronics, I think 12 bucks and that took care of it but I would still like to find schematics for both the PA and the input modual. I have spoken to E-V and they are just dicks. They don't want me you or anybody to have them. There were a couple of people on Ebay who would repair your amp plate for about $150.00 which is fair. I'm still looking for the prints so if anyone has them please share.

thanks,
Phil

Electro-Voice ZLX-12P about 5 years old.

I have alot of "white noice" on Input channel 1, not on channel 2.
It's increase when turning gain up.
The noice is there even if I have no input signal/cable connected.
See attached screenshot of the noice frequency recorded with my phone.

The speaker is also running hot, even with no input signal.

Over 50 degree celsius on the back of the amplifier without any input signal, after only about 5 minutes.
Inside it's 65 degree celsius.

See attached photos.

I'm normally using my phone or TV to connect to the AUX input. (I think that might have caused the problem).

I only used it at home, almost never on high volume.

Thinking about replace the DSP board with the new one that have Bluetooth.

Thanks in advance!

I would copy and send it to you but I haven't been able to find one Electro-Voice won't part with it. If it is an audio output problem just replace the output IC which is available from Mouser electronics. I've replaced those a couple of times.
