I have the AVR588 7.1 Surround A few models down from the on mentioned here. Same problem, turn it on then after warm up of a minute or so it shuts down and the standby red light flashes. It has the same part failure. KIA7915PI. Ive ordered 4 so I have backups since this seams to be a high failure part. I tried crossing the part to a higher quality part like NTE but I cant find one. My searches on the net I did find many have the same problem but noting on resolving it. The way I found the problem is I associated it as a termal issue so I got a can of freeze it at an electronic supply store and cooled several components one at a time cooling it to see if I could keep the unit on longer. Low and behold as long as I kept the KIA7915PI froze it would stay on. Im still waiting for the parts but to get by I have removed the transistor and soldered three long wires to the pc board in place where the transistor was and the part soldered to the other end. This is to extend the part out so that I can keep it cool in a glass of Ice. I dont recommend anyone doing this if your not familiar with electronics. I was careful soldering the leads of the transistor to the wires not to cross them and make sure not to emerge the leads of the transistor into the water as the ice melts. Crazy but it works for now. As I wait for the part i can kick back and watch some movies with some rum on the rocks as my receiver enjoys its 15v regulator too "on the rocks". LOL

The KIA7915 is not a transistor, it is a negative 15V regulator. The 7900 series, and the positive version the 7800 series, are commonly available parts. If you search for 7915 without the KIA, you will find many sources to buy them from. One place that is good for electronic components is Mouser.com

Denon avr-1513 shutting off and blinking red light


Sounds like you could have a bad speaker connection. Try disconnecting the speakers and see if it stays on. If so, connect one at at a time until it goes off to determine which one.

Only red light is blinking on my denon avr 1508


It sounds like you overloaded the Denon avr with too much resistence from the speakers. Please check the total resistence of the speakers before you connect them all. Also check that the speakers or their wires are not shorted!

You don't say how "TV audio" is entering the system.

My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.

I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.

If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.

You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.

AVR-1910 & Bose Lifestyle 35 setup


Bose Lifestyle (and all Bose-amplified speaker) products and their speakers are SYSTEMS and should not be split up or intermixed with other brands or models. Damage will probably result. Proprietary connectors provides a clue.

The digital audio out should work with the Bose. You could still use your Denon to drive a conventional sub in your scheme, but you would have to manually match volume with the Bose. Or go Full Monty and buy a full complement of speakers for the Denon, retask the Bose and slave its sources to the Denon.

Hope this may help but you will disappointed. as heard from some pro, your amp will blow up the bose cube if direct connected to them, they are powering down your output to fit their tiny speaker. My understanding was you have to hook up everything to the bose module. They don't like to play with others.
