Front buttons on my rxv 430 not responding - Audio Players & Recorders

Does the remote work the functions that correspond to the front panel buttons? The front panel board could be faulty. you should get it checked by a technician.

Try holding the 'tone control' and 'info' buttons while you hit power. If it is locked in protect mode, this will release it.. If it turns right back off again, it needs servicing.

It could be a power supply problem from one of the control PCB,s but it may also be a setting that you can change. Some equipment has provision for "dimming" the front displays so that they are not as obtrusive or glaring. See if there are any settings or adjustments that can be made from the front controls or if supplied with a remote, there may be an LED / light control button or option.

Good for you. You are a real techie.

The problem can be the cable or speakers or RX-V463 or settings. Need to check one by one.
Set the RX-V on DTS or Dolby Digital
1) Check Cables - connect the 2 (surround) cables from RXV's Centre Out to Centre speaker. If the Centre speaker works, then cables are ok.
2) Check speakers - Connect each Surround speaker to RXV's Centre out. If it works Speakers are ok.
3) Check RXV - Set it on DTS or Dolby Digital
Connect RXV's surround out (one at a time) L and R to the Centre speaker. If there is no sound, the problem could be RXV's settings (I need to read the manual).

Hope this helps.

The amplifier for this channel is NOT working.

Adding on again: I have interchanged speakers, if i connect any speaker on the right front channel it will not work. When I do a automated speaker test only right front channel does work.

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

First do not panic by seeing all sockets in the back side of the receiver.You can connect 5 speakers and one subwoofer on the speaker A switch and maybe a second pair of stereo speakers on the B switch.All the speaker sockets have red and black terminals, so do all speakers. Just get decent cables ( You can buy a whole connection Kit if you want ) and connect the corresponding outlets to you speakers.If you have a powered subwoofer connect the subwoofer input to a socket labeled Subwoofer pre out on the RXV. You will need a RCA to RCA cable for that Next you will need a coaxial or Optic fiber cable to connect a DVD player digitally. The back of the DVD player will have a socket marked coaxial out, and so does the RXV's backside. Just link them .
Turn on the system everything should work. If you are not getting DVD sound there is small button on the RXV front panel called Digital input -- set it to auto ( keep pressing the button and it will scroll through various modes). Also remember to switch on speaker A on the front panel.

Do you have the receivers "Audio Input" set to "Auto?"
There is a small button on the front of the receiver to set audio for either: "Analog, Digital, or Auto" and you can double check it in the "On Screen Menu", "Manual Setup" "Audio" Hope this helps, if you still have an issue, check the "Source"(DVD,Cable Box, etc) setup mode as well.
