Hello Everyone,
I have purchase a peavey XR800F version powered mixer that has a issue. The mixer is powering up and signal can reach in to the mixer but the left side power amp is not working. One of the thing that i find is that on the left side of the mixer there is a side grill when the mixer is running couple minutes i smell something is getting very very hot and i can feel heat underneath with some burning smell. i have openend up the mixer and removed the heatsink to check if the mosfets are broken of burned down but that is not the case.
The heatsink gets very hot on the left side but the right side is cold stone. if the mixer gets hot i shutdown the mixer because i dont want to break the mixer completly .
Are there know fixes or schema of the mixer what can help me to identify the issue. I have soldering skills so that is not the issue just need some help where to look and possible parts that need to replace.
Thank you guys.
