Yamaha HTR-5170 amplifier shutting off & not powering up
Hi there - I have an Yamaha HTR-5170 amplifier that has been shutting down on me intermittently& I can not figure it out. After checking all the connections, speaker wires on the all 5 Bose speakers & impedance it still will power off on its own. Sometimes it will not even power up & stay on it just keeps shutting off. This unit was taken to an authorized Yamaha repair shop & it was worked on for a week & it never once shutdown on them. They said they ran it through many tests/loads & it is working well. Well, no it's not...I can not listen to the radio, play a DVD or watch a movie on the satellite dish in 5.1 surround. Maybe this information will help solve my problem, I just recently bought a Samsung 60 inch DLP HDTV & since then this has been my life with my amp. Please help, Sammy

I assume you want to slave it to the receiver and drive some more speakers with it.
Connect some RCA cables from whichever channel pre-outs you want on the HTR-5860 to any input on the AX-596.
Set the AX volume to something sufficiently high, run through the HTR's speaker level setup and match the AX volume to match the channels on the receiver. Then leave the AX's volume alone.
If you just want the AX to have access to program sources of the HTR, run the RCA cables to it from one of the VCR1 or 2 Out (but DO NOT select whichever one you use via the front panel). These are not affected by the HTR's volume controls.
1-first try to keep good ventilation around it and confirm that the air flow in and out is completely free from any blocking thing. 2-clean it by air blower. 3-if you use remote control to power it keep it far away and all other remotes also. 4-disconnect all your speakers---- and try to test the amp one by one.until you find the bad one and change it-----if all above not working you must send it to service center near you.
The unit has an internal problem and is shutting down. This is also known as protect mode. Since there is nothing connected at all, the most common cause of this is shoerted output transistors. Expect a parts cost in the $40 range plus the local labor rate for the repair cost. Let me know if you want to attempt the repair.
