Hi all,

I've had a Sony MZ-R90 poratable MD player for the last 2 years almost, and have been really happy with it. However, a few months ago, the unit started exhibiting weird behavior. Sometimes the buttons would mysteriously get mapped to other functions for a while (ie - pushing the jog dial in would actually skip forward a track, pressing stop lowered the volume, etc). Early on it would eventually go away, but these days it's been more and more presistently stuck in this mapped state. Has anyone ever had this sort of problem with their Sony MD portable? Or are there any good sites out there dealing with fixing Sony MD players? I'd like to fix this myself, instead of paying inflated rates to get it fixed at a Sony Repair center.


Thanks,

Chris

hongman, this problem isn't isolated - but most of the time the remotes go before the actual units.

Hi,

Yeah, I figured. However, I stopped using the remote a while back, so maybe that's why the problem's showing up now.

Sounds like it is time to dig up that remote again!

Maybe you could take the face off, and see if anything is shorting the PCB...?

Did you ever get a fix for this, I have the same unit with the same fault. Hope at some point you didn't get it fixed and sold it as I may have ended up with it :) lol
