Hi,
So I have this problem with my remote control: all buttons are working except for the Volume up and down buttons. Currently the output level is at max so at least the Volume down button is not working.
I opened the remote. It was clean but I did some cleaning anyway. I hooked up two scope probes at both remote's LED ends and upon touching the Volume buttons I got similar wave forms I got from other buttons so at least now I know that the PIC is working. My guess is the remote commands are not reaching the DAC or something. I haven't measured what signals are reaching the DAC yet.
I also have one more problem with the transport. When I close the tray regardless of whether there's a disc in it or not it would start making "rotating noises" but after that it will spit it out. I opened the player and noticed that despite those noises nothing is rotating. When I shake or hit the chassis it will start working properly. Once it's working there are no problems with it.
I would appreciate if you have any ideas concerning those two problems.
