I would like to open the remote control of my Yamaha RX-V800 Receiver in order to clean the contacts. It has only one small screw in the batteries compartment which I took off but still I don't know how to open it without damaging it.

Rav-212

a couple of subtitutes:

$133 and $55

or you could buy a whole RX-V800 WITH a remote for $136 delivered...

What if you DON'T use the remote? Does it shut down when just using it?

If SO, you have a bigger problem.

If NOT, it sounds like the remote is hosed - sending a code to shut off.

Do you have another remote of any brand that you could set to do something simple, like change volume? Don't train it from the original, though, or it would do the same thing.

(I have the RX-V659). Because the Yamaha remote has TWO SEPARATE buttons - power ON and power OFF (standby). This problem can't be fixed. There's a code to choose power ON and another code for power OFF. But one button can't be two buttons. Bad engineering\ design by Yamaha in my opinion

Remove the small screw in the battery compartment then put the long edge of a kitchen knife in the groove & twist. The case will snap open at that point then work your way around until it parts. Clean the contacts inside with Isopropyl alcohol & that should solve your problem.

Hi there,

I bought my RXV800 in late 2001. This amplifier is absolutely fabulous and I understand others -like me- being unhappy when it starts to fail. I have the volume control issue as well, it started to work normal for at least 5 years, then there was a period of 1 year that the volume neither went up or down when you turn the volume control and then finally a 3rd phase was that it more or less works reverse.

It is solvable and I repaired it myself for $ 0,0. The only requirement is that you are a bit handy. You need to open the box and find yourself a way to the volume control (and you know where this sits of course) because this is the one that needs to be repaired. This is 35 screws away from you in total but this sounds a lot worse than it is !

It is indeed the volume control that needs to be repaired. In an analog amplifier this component would contain a resistor (potentiometer) but hey this is a digital volume control and looks from the outside the same but isn't at all. You need to take this volume control with 5 contacts of its print with a soldering iron. Open this potentiometer lookalike and clean it with some absorbing paper. The issue is that there is a kind of oil/grease from the shaft (which is there in order to turn smoothly) which has leaked into the area of the contacts in the middle. Just clean it and turn 50 times with it in order to spread the remaining oil/grease if there would be any. Close it again, solder it onto its print and switch on the unit... you will see that it is repaired... not for 1% or 10% but for the full 100%.

Hope this helps !

Regards,
Dirk

ps : enjoy your RXV800 !

email me .... [email protected]... ill send
you a copy of the codebook page... but let me try and locate it first, i have the same unit before. Yamaha code books are the same also to other models.

it can be accessed via the main unit controls but you need to go through your manuals. Maybe you can get your remote repaired still... maybe not badly damaged caused by corrosion.

Hello!!! Are you electronic technician? You should see the transistors Q22A, Q22C, Q19C e Q19A and its drivers on Main Board. All the best, Rasgador
