Behringer qx2222usb Schematic

[bsco]

Searched the net but came up empty....anybody by chance might have schematics for this one or know where I can get them? Customer compliant----powers up...all lights on and no sound...It worked for me..I am thinking power supply issues but it would be nice to have schematics if I can get them.....will tear it apart tomorrow...

ALl lights on, as in all teh peak lights and such?

That generally means a missing 15v rail (or 17v, whatever this one uses)

That is something I am not sure off as it is working for me...I am going to have a look at the power supply when I go over to the shop later this morning...I have been up since 2 AM...couldn't sleep..6:45 AM here now......must be 5;10 AM your time...I'll let you know what I find.....

Just got in....I checked it out..there were two 1000uf/25V capacitors that were bad....one of them had the seal completely let go and when I removed it the outside metal shell came off as well.....replaced them checked the other caps...working good now......
