Pioneer Amp/Receiver VSX-D466S remote malfunction

The unit cannot be controlled with a remote control device. I used the OEM remote and other universal remotes with no success. The OEM remote does control other devices such as the TV and DVD player, but not the amplifier/receiver that it is designed for. I am inclined to think that it might be a malfunction of the internal remote sensor of the unit itself but have no idea how to repair this or to know for sure if that is the problem. I have tried the manual reccomendation of unplugging the unit to eliminate a problem with static interference with no result. I can most likely repair this if I know what part it is I need to buy and where it is located inside the unit. PLEASE advise.

Sincerely with gratitude,

    The problem is the Pioneer remote that came with the amp/receiver does not work for it. The Pioneer remote does work to control other devices just not the one it was designed for. I tried universal remotes to see if the Pioneer remote was defective but NO remote Pioneer or otherwise works on the unit.

    I would appreciate a having a general idea of where to find the remote sensor with in the unit to see if possibly I could repair or replace it to restore remote function of this unit.

Hi, I am convice it's not the amp itself, is your remote a pioneer, if it isn't then it's your remote. Even thought you have bought a universal remote, it doesn't garanty it will work with any device,.... take my word, i've seen this costantly depending on the age of the unit.
If it's a pioneer universale remote, you would have to get the schematic for the amp and trace the opto sensor in the from and see with a scope what is the output of the sensor that goes to the micron, could also be the amp stage, sensor or micron that's causes your problem.

If some reason this is all bla bla bla, then just see if the infrered sensor for cold solder joint or a cracked board .

I hope this help

    Ok Your problem is not the remote sence it works with other unit's, you would need to troubleshoot the amp inself. If you have a scope this will be very helpfull. You must open the amp and find the sensor that receiv's the signal and trace it back to the micron ( IC) when pressing the remote the signal at the sensor should change, only can be seen with a scope, there should also be at one of the 3 pine's of the sensor a 5 volt. That must be there, what I realy would be looking for is a cracked board, if you folow the sensor copper conductor, or circuit you will see that it goes to a resistor then to an ic, this ic tell's the unit what to do if a signal is present. I have seen in the past bad IC's witch would function the remote and other functions. You will have to determine what step to take after. I would strongly sudjest to send to a pioneer directly to have it repaired, not a depot.

    I hope this help

I have the same unit. It does come with a remote. The original remote is pretty much impossible to find. But also there are some companies that sell remotes for it. Google Pioneer VSX403 remote replacement. I have yet to get a remote :D
Good Luck.
