SOURCE: Power loss

Its possible that one of the speakers wires are shorting out or touching the case of the unit (leads to protective shutdown).

First, hide the remotes so that the TV cannot "see" it. If the problem goes away, it's the remote. Other than that, it sounds as if the receiver is faulty...accordianman

SOURCE: Yamaha Receiver sound cuts out with Dolby Digital.

Your problem is related to HDMI technology not the Receiver. HDMI in it's current version 1.3b has worked out 90% of the current problems being reported by HDMI users. it's a problem with HDCP digital copyright protection and the recording industry not wanting us "consumers" to duplicate or record their DVD's. Your receiver and every other receiver with version 1.1,-1.2, & 1.2a just don't cooperate with BluRay and even HD Cable or HD Sat receivers. If you just purchased this receiver recently, return it and get an 09' model or equivalent with 1.3a or 1.3b HDMI technology. If this unit is "un-returnable" then, what needs to happen is you need to run component video and digital audio to the receiver OR Run your HDMI directly to your TV and run a Digital Coaxial to your DVD audio input on the receiver. Depending on how many sources you are running to the TV via HDMI will be limited to the TV's capability (how many HDMI inputs)

Now, if your TV is 50" or smaller, the difference between running HDMI and Component is unmeasurable to the human eye. So, if you have to run component, don't sweat it! just use good cable, ie. Monster, Phoenix, Translucent etc. I do theese installs every day, and I still prefer Component or DVI if available over HDMI. They just haven't proved the reliability to me yet and we're three years in! Hope this helps

sounds like you have the polairity reversed on the speakers
and yes it does make a difference
check polairity also make sure unit is well ventelated
you wouldnt use your compouter if it was inside a card board box
so make sure the reciever can breath also
recievers get too hot and they start blowing chips off the board

SOURCE: humming sound when watching tv,but not when watching dvd's

It wounds like you are getting interference from you tv to the receiver. You can try a few different things here.

1. Connect the tv output into another input on you receiver to see if it isnt the channel on the receiver.

2. Try a different set of cables between the tv and receiver. Faulty cables can give you problems.

3. Connect the cable from you tv to a different device. (another dvd vcr blue ray etc.) This will tell you if its the receivers or the tv.

I was hooking up my sisters surround reciever for her and used an optical cable to the reciever from the TV. Her TV gets signal from the cable box via coax and uses HDMI from DVD player. I am stumped that...

srry but the tv is not capable of sending hdmi audio through its outputs the dvd player audio must be run through rca red and white or black if you have digital audio out to the back of the receiver on its own channel

"Protect" feature increasingly activated.

You may have an output transistor gone bad and it is trying to run on one good transistor since they commonly are used in pairs (one positive and one negative). Time for a trip to the shop. Good luck.
