SOURCE: Programming manufacturing code
I tried to program the remote supplied with my Time Warner HD-DVR, only to discover that ... using the proper Yamaha code only allows you to turn the HTR-5740 off ... not ON!
I had to get the programmable version of the remote, and use its "learn" function to assign the "power on" function to an unused keystroke combination on the remote!

You can use a hi-level to low-level adapter. Just remember, the Yamaha does not send power (wattage) to the sub, just signal. You need to use a subwoofer that has an amplifier either externally or built in.

i talked to my father in law who knows quite a bit about these. your only option is replacement. i wish i had better news. i know what they cost and i have one as well.

Most Yamaha remotes work on other Yamaha receivers. I would say yes because I had to do the same thing, and it works.

Hi,
The receiver turns off as a self protective measure when ever it detects an internal fault.
Due to other reasons too this will happen check accordingly and replace it.If you don't have hands on it,ask help of repair professionals.
1)Amplifier on the right and left channel is defective or burnt this happens
2)If you don’t see anything like that look for discolored or burnt components, smell is very helpful as overheated components can be very lightly discolored but the smell of a burnt/overheated component is unmistakable.
2)Heat is always an issue to check for, your best bet, without taking it apart is to try and cool it externally.
3)Check for firmware updates.
4)Sometimes a dodgy power supply can be the problem, spontaneously not providing enough power to keep it running.
5)The audio output transistors are mounted to a large heat sink which keeps them cool during operation. They are electrically isolated from touching the heat sink by an electrical insulating washer. But, in order to keep them cool and allow for good thermal conductivity of the heat generated by the output transistors the washers are treated with a heat conducting grease. Over time this grease will dry out and lose its heat conductivity ability allowing the temperature of the transistors to rise. as the heat goes up they conduct more current and cause the protection system to activate and turns off.
post a comment for further assistance.
thank you for using fixya have a nice day:-)
