You will need to trace from the point of the AC to the power unit. Use a multimeter to trace using the right range to check for the ac and the conversion to the DC side. Check to see if there is any fusible resistor failures to the main board. The fault can be numerous and you will arrive only with a systematic approach to the main board. Good day

Hello i have a yamaha RX-v459, and i have an HDTV, can i connect my cable box to the yamaha and the yamaha to the TV and get HD? the Yamaha does not say HDTV, does that matter, or will i still get HD?


Yes, the cable box should/could be treated as any other digital audio device. The video could also be run directly to the TV as it doesn't actually improve from being routed to/through the Yamaha, does it?

The labeling on a given input is irrelevant (except for "PHONO", which is literal and exclusively for a turntable).

Yamaha Cinema DSP Natural Sound System AV Receiver #RX-V459 was installed in 2005. It has never worked correctly. It sets on an open entertainment center. It has space all around, 2"on top and...


Are you saying the unit dies in 30 seconds at home but it works fine at Radio Shack?

Maybe you need to assess your power sourcing or any other condition that's unique.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Eure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

I getting noise in yamaha rx-459 please help.


I used to get noise as well. It turned out to be that one of the cables to the speakers was loose. Try tightening the cable connections to the Yamaha and to the speakers.

YAMAHA YDS-11 TO A RX-V459


Hi, as per yamaha site RX-V459 doesn't have the DOCK connector which is used by YDS-11 dock (or the bluetooth module). This is the only possibility to connect the YDS-11. YDS nor receiver don't have USB connector and they are not needed.
For example RX-V465 does have DOCK connector and supports YDS-11.
For your receiver, you can use only analog audio cable with your iPod.

Vocals missing while playing with 2 speakers


Go to the amp "Basic Setup" and alter basic setup according to
- the size of the room (details in the manual)
- alter the no. of channels e.g. if you have only 2 front speakers, change the channels to 2.1 (.1 for the subwoof)
- Once the setup is changed, the amp pumps in sound according to the set up

All the best
