Hallo,my name is Peppe and I am an italian technician (Naples). My english language is not perfect but I try to explain how repair the receiver because the mine have the same problem (don't power on after 4 years of regular use ).
The bad component is the capacitor C405 (22nf 630 v )on the relay power board,the same board where are the two socket for the ac outlet.
I hope that my solution help all the persons wich have this problem on this very beatiful amplifier Yamaha RX-V450.

22nf 630dc/300ac capacitor inside back left board, i found mine on top of this board, a magnifine glass will help to check the writing on capacitor, replaced mine, works as new, g.knight. uk. ( rs components.)

Remove the small screw in the battery compartment then put the long edge of a kitchen knife in the groove & twist. The case will snap open at that point then work your way around until it parts. Clean the contacts inside with Isopropyl alcohol & that should solve your problem.

Maybe if you SET it up right you might not need to REset it.

Find the manual and carefully evaluate every indicator on the face to make sure you understand what they mean and how they might affect operations. Look for Speakers NOT enabled, Muting ON, a Tape or other input inadvertantly selected. If you fail to find the errant setting, treat it like a new install and set it up all over again according to the manual.

Hi! Transmitting doesn't mean it's working, What you should do to test it is use a good quality universal remote such as a Logitech Harmony and first program the preset code for your receiver into the Universal Remote. If that works, you know your OEM remote has gone bad, at least for those buttons. If it doesn't then you you should attempt to have your Universal Remote "learn" the IR signals from your receiver's remote If the controls still don't work, there is a problem with either your IR receiver on your receiver or the the circuitry that proceesses the signals into commands. Good Luck!
