Hi evebody i have a chase hq board (cabinet) with a sound issue no sound at all! ia have replace all capacitor ! can someone help me please im so desperate:(
 
First you have to determine if lack of sound is due a fault in analog or digital sound circuit.From picture on the Net this PCB should use two OP-AMPs in the sound section (TL074 or TL084) so my advice is to check or replace them.
