Do you have it installed with plenty of ventilation?

yes there is plenty of free space up the device,more than 40 cm free space,with nothing of course on the amplifier....is the first time that an amplifier from others that i had in the past, reaches that high level of temperature...i have an older model the rxv 363 and ,even if it works hours never become that hot.....i am curious to know if the service tha authorized service ,that they examine the device are telling the truth....that that model 's function is normal with high temperature...if someone who has the same model had noticed the same thing,thank you

Heat is often the result of the video card installed rather than from amps although model specific questions are generally better posted in the specific Owner's threads .....

One question is what does hot mean to you? The tool of choice for measuring the temperature is the non-contact (Infrared) point and read thermometer. The AVR manufacturer's haven't gotten smart enough to have a temperature sensor(s) inside that you can read out with the remote control. Some of the AVRs have at least one, but they don't expose its actual read out even though its just a bit of firmware programming.

This seems to be unusual, in my experience with Yamaha receivers, I've had 4 different models over the past 20 yrs and the all seem to run fairly cool. Just to check I got up last night after my receiver had been on about 4 hrs and it was only warm to the touch. Current receiver is RX-a820 and it has less than ideal ventilation.

I have the 673 and have to say how surprised at how cool it is even after longer run times. I Have the Onkyo 805 ant that has always run "hot" but the Yamaha is not even close, at least to touch on top cover.

See if you can return it. It sounds like you may have a bad unit.

The third day from the date of buy,i took it to the authorized official service in my city,the personnel here said that INDEED the temperature in the unit is un unsually high....and becouse they couldn't REPAIR it,they put on the box a sticker 'FOR REPAIR"... and they sent it in Athens..in the central authorized service....After a week...the central service from Athens called me and they said that there is nothing wrong (?????!!!!!!!!) with the device,that everything is normal during the operation....and till now ..they support the same thing....
i proposed to send ANOTHER unit here to test it ,in front of the personnel of service or in the authorized dealer,where i bought it ,and to verify if the temperature in the first unit is normal....and they denied it..i proposed to buy the next model the rxv 675 and they denied it....
is extremely suspicious the fact that the main service in Athens insists..to give me the specific unit with the 'problem"
if please somebody knows WHERE i can send an e mail...in another sector of yamaha ,probably in another country to explain how the things are
thank you

Where did you buy it? I would talk to the mgr there. If you can't get any where I would at least demand an extended warranty.

OK, well it sounds like you're in Greece. Seems like par for the course as to how things work over there. No offense. smile.gif

Maybe this link can help
