Onkyo DR-S2-2 START BLINK AND SHUT OFF

Have already posted this fix: Most common failure is the audio amp IC, reference # Q5001, which is an STK402-950 (Onkyo Pt. # 222123). Typically fails as a result of excessive volume levels or as a result of problems with the speakers or their wires. If you're technically inclined, the part can be had from various vendors & is fairly straightforward to replace once the complex disassembly required to access the PCB this IC resides on is accomplished, using standard soldering skills. A repair of this type by a reputable servicer may be more effective for non-technical folks, as typically can be accomplished for $200 or less, much less than replacement cost...
