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

    Does it trip when all electrical connections to the DLP HDTV are removed?

I agree with Jango. Go back to the setup when it last worked. If adding the DLP is the problem, you may have some sort of a ground loop formed between the TV and the receiver. good luck...Rob

What are the consequences of connecting a Yamaha htr 6230 amplifier running on 120 V with a 220 V power point.

Bad idea if the system's power supply does not support switching for 240ACyou will fry the unit and there are no benefits to doing so. Please provide more details

Hello i was wanting to know if i could hook up my AX-596 amplifier to my Yamaha HTR-5860 reciver

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.

My Yamaha HTR 5920 Amplifier

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.

AMP Power

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.

When I turn it on the fuse blows up.

It will need service.
I would call the music store closest to you that sells PA gear and ask who fixes theirs.
