Hello group, I am having a problem with my JVM410h. Clean channel all three modes and crunch channel all three modes work perfectly.
OD1 and OD2 are a different story, they appear to be stuck in a very low volume mode, you can still higher and lower the mastetr volume but you can only get a small % of the volume you are supposed to get. All other controls work normal.
The only things that don't work are od1 and od2 individual volume controls. I am in the middle of moving right now so all I can do is get an idea from the schematic. I posted it below and it opens in the form of a pdf file. The schematic that has caught my attention is the front panel schematic labeled jvm410-61-02-iss1-1. At the top left is the volume control. The first thing I would like to do is check R219 but I am wondering how to check the relay RL204b, is there a way to check it with out pulling it out of the circuit? Is there another place you would start your search?
