Question about Yamaha Rx-v465/rxv465 Home Theater Receiver

Open Question

Do you have detailed troubleshooting checks and suggestions?

Hello, I'm troubleshooting a RX-V465 Receiver. There is no sound coming out of the receiver speakers or headphones.At initial power up there is the main relay coming on and several others clicking within 3 to 5 seconds. I'm sending music through AUX and AUDIO 1 AND 2 for testing. I entered the Self Diagnostic mode and there was a message - Protection for THM PRT:---. Output of the thermal sensor on MAIN PCB 5 on the heatsink was 1.6 vdc at ambient terperature which appears normal. Replaced the thermal sensor anyway and have the same results. I cleared the protect message in section 21 of the diagnostic, performed 24.PRESET RSRV, unplugged the unit, reconnected, and repowered receiver. Same results, no sound. Entered advanced setup and reset to factory settings. Still no sound. There are no more THM PRT messages in diagnostic history. There is no relay clicking when going between sources. I believe the protection circuit is activated. Do you think that one OR both of the STK-433 s are bad causing the protection circuit to activate? Thank you,

This could be as simple as having input and output line audio reversed. Please check all sources for proper connection. You can do this at the receiver too, but not both receiver and sources.....accordianman

Speaker wire contact with each other is the problem. Check the back of ALL SIX speakers including sub-woofer. You should find wires contacting each other. Fix that and your problem will be solved.

In that case the amplifying circuit that delivers the output to the front exits has failed. You must dismantle the receiver, locate the circuit, unsolder it, order an identical replacement either from Yamaha or from an parts site and solder it back.

SOURCE: Yamaha RX-V663 turns off right after switching it on

The display of PS2 PRT means there is a problem with the power supply. Could be a voltage regulator gone bad, very hard to tell without getting inside.

Can you help with in-depth technical troubleshooting as the service manual does not go into detail.

Doubt that it is either of the STK's. If they are bad, then you would get a DC protect error and the unit would shut off. Most likely problem is either your digital board is bad or the volume control IC on the bottom of the main board.

While on vacation my daughter was house sitting and my home theater set up stopped working. Specifically, with cable to my cable box and HDMI feed to the Yamaha RX-V465 receiver, I get good HD picture on...

If you suspect a setting was changed why are you tampering with the cables?

Get into the manual and go through every setting. Troubleshooting sections usually help. If it's just the Cable Box audio look at IT. Assign the port. If it's ALL audio start with the test tones.

I have a Yamaha RX-V465 receiver. Is the newer YDS-12 docking station compatible with this receiver? the YDS-12 seems to accept newer IPods.

Yes, it is compatible.

It has 2 modes of operation. For RX-V465 you need to select mode B. In this mode it is compatible with YDS-11, which is supported for RX-V465. But iPhone is not officially supported in this mode. But I have found on Yamaha website FAQ, where they claim that iPhone switched to Airplane mode worked well.

Yamaha av Receiver RX-V465 picture but no sound. Can switch between PS3 and sat tv all via hdmi connections. Good picture yet still no sound. Trying to run left right and center Bose speakers. Read the...

Check the settings on receiver in the SETUP menu / HDMI / Audio. Here you can choose Amp (sound goes from the speakers connected to receiver), TV (receiver is muted and sound is routed via HDMI to TV) and Amp+TV (sound goes from speakers and also to TV).
Also check in OPTION menu / Signal Info that receiver is receiving sound in recognized format.

Haveing trouble syncing the sound with lips is there a trick to do this? also whats the best setting to get the best true surround sound by the way i have Rx-v465 with klipsch 300 home theater speakers.

RX-V465 has auto-sync feature over HDMI. So if you have your DVD and TV connected over HDMI, receiver will communicate with your TV and set the delay automatically based on TV processing speed.
You can turn auto-sync on in Setup menu / Sound Setup / Lipsync / HDMI Auto.
Or if that doesn't work for you, you can set a value in milliseconds manually in the same submenu.

I get no bass sound from sub-Woofer connected to Yamaha RX-V465

Check your speaker settings in Setup menu / Speaker Setup / Manual / Config (and then in this submenu also Equalizer).
In Config, choose where should low frequency sound go - subwoofer and/or front speakers (if they are big enough). The settings are: Bass Out: SWFR/Front/Both.
Also check Subwoofer phrase in SWFR Phase.
Check settings of all speakers, they can be Large / Small / None. If small, frequencies lower than "Crossover" settings, will not be put on them.

Unfortunately the RX-V463's HDMI output is version 1.2 or 1.1. In simple terms, It is useless! Not to blame yamaha or any other manufacturer but the firmware was riddled with problems; just like what you describe. There is no fix for your model for the video issue, however, the optical issue is solveable. The receiver should play 5.1- 6.1 7channel stereo etc. in optical or coaxial mode. If you have the ability to switch to coaxial, do so. it's sound is warmer anyway. Secondly, check your settings thru the receivers "GUI" or "Menu" in Manual setup for audio. Thirdly, check your samsungs "Native" resolution, chances are it will only do 720p or 1080i and; if your TV is 50" or smaller, the human eye cannot see the difference between 720p and 1080p anyway, provided you use good cables. I am a professional in the industry and still avoid using HDMI whenever possible!
Just make sure you set your BluRay and TV to the same resolution. If your choices are 720p or 1080i use 720p it's cleaner 1080i is equal to 540p, which is just a hair over std DVD video. If you still have problems and need more help, post a comment and I will help some more. Hope this helps
