Onkyo Input Selector Fix

This is an Alternative solution to fix the Onkyo Input Selector issue.
This fix might even work for any amp that uses ALPS 1017 Input Selector.
You can find the schematic of the circuit in below link

i fixed my input selector with a quick and easy fix...i took the straw for my canned air and crushed it in a vice. This allowed me the clearance needed to get in those spaces behind the knobs and dials without opening up the unit. I just sprayed it in there while turning the knob a few times. Spray from different angles so you crosss-spray the potentiometer. Good Luck. Worked great for me.

Hey thanks for your reply. In my case the ALPS input selector's gear was crushed and jammed So the only way to fix it was find a replacement ALPS selector which is not available in market So i decided to solve the problem in the embedded way.

ingenious solution

Very clever indeed! 👍

mi onkyo no servian la seleccion de entradas lo que tenia mal era el motor sucio trabado que va en la placa donde van los conectores rca

What I was thinking on, is to replace the resistor array with a single digital potentiometer. Where did you got the Vcc and GND from? A pinOut diagram would be great. Also the resistor levels for the output they means, with the changing sequence (if it is not incremental).

Good idea! But there are 3x8 analog demux chips available which can be directly interfaced with the Atmega. That would have significantly reduced the space needed for the board. 😀

Can you please recommend one for audio?!

[@shriramkashyap7788]

The analog multiplexer chips have significantly high contact resistance when the switch is closed, this can bring down the quality of the audio input when it reaches the power amp section. That was the main reason I went with these micro relays which will have 0-ohms resistance when closed

Hello Shriram, Can i have the circuit board layed out components and connection diagram to msin board. I am having the same problem with A 807. I am willing to pay for the circuit components and other charges. Thanks

My input selector of 915r broken gear and dirty mode switch !! Do not change function and Led of function blink Goodluck I can find 2 new gears from my toys.and motor from old cd player. I clean 3 rotary switch in selector box and install new motor and gears . Try to alignment 3 rotary switch and gear to initial direction

Hi. Very good video. I have the same pb on my Onkyo. Can you sell the suitable electronic card? Thanks

[@shriramkashyap7788]

Hi, Please share some pictures of the internals of your Onkyo Amplifier (Like the ALPS Motorized selector, Input selector switch circuit located behind the front panel, etc) to my email. My email id is [e-mail]. The solution shown in this video is custom tailored one to suit the number of data lines in the input selector circuit of my amp. For me to help you with this i need to understand the number of data lines and Input selector switch circuit of your amp. Thanks

Hi. Nice work. Please describe the PCB contact

[@joachimh.9000]

why don you just open the switch , clean it and solder it back. Thats what I did....

[@bongdan]

i just cleaned it with spray and works again without taking it out
