Swordsage Posted November 30, 2010 Report Share Posted November 30, 2010 Ok... I have a model MZ-NH3D that I've been using as my main player. It's been working just fine for a while now, but recently it's been having problems with the remote. For the last week or so I've noticed that sometimes it wouldn't register button presses, or the screen would even go blank. It then got worse yesterday, when it stoped working with the remote altogether. At first I thought it was the remote itself, and didn't mind too much since I had spares... however, it didn't work for the spares either. And every one of those remotes works fine with my RH1, so it has to be something wrong with the NH3D. Does anyone have any idea what it could be, and how I can fix it, if able?

Azureal Posted November 30, 2010 Report Share Posted November 30, 2010 I agree with the wizard. It sounds like the contacts are tarnished. The ones on the remote are a breeze to clean, the internal ones on the unit, not so much ... Radio Shack used to sell "Contact Cleaner" spray which was a small aerosol can of compressed fluid that could be sprayed into tight apaces to perform this exact task. Might be worth looking in to. You can check mouser.com or digikey.com for an online source of something similar. Quote Link to comment Share on other sites More sharing options...
sfbp Posted November 30, 2010 Report Share Posted November 30, 2010 Remotes work by changing resistance. Dirty contacts change the resistance too. Contact cleaner is available at all electronics stores (I don't mean Best Buy etc but even they might carry it). Quote Link to comment Share on other sites More sharing options...
Swordsage Posted November 30, 2010 Author Report Share Posted November 30, 2010 OK.. so I need to get some contact cleaner. I guess even if the remote is always connected to the unit. air is going to get in there somehow. And all metals end up oxidizing in some form or another. I am a bit afraid of trying to bend the connectors though. I have no idea how far they are supposed to be bent, and I really don't want to ruin this thing, Quote Link to comment Share on other sites More sharing options...
Swordsage Posted December 19, 2010 Author Report Share Posted December 19, 2010 Hey there. Sorry I'm updating you guys on this so late... been a crazy last few weeks. Anyway, I went over to Radio Shack and got their contact cleaner. I followed the instructions and sprayed the contacts on the unit. Yet the remote still won't work with it. I've sprayed it several times since, but no dice. I've played around with the idea of wiping the contacts after spraying, but I just don't have any sort of q-tip like tool that's small enough to fit in, plus I don't want to damage things any further. I guess this may mean that the contacts may have to be bent as the wizard suggested (sorry for confusing your words earlier), though I'm not sure how they would have been bent out of alignment if the remote had almost always been connected. Maybe it's just that my contact cleaner sucks? Quote Link to comment Share on other sites More sharing options...
