TEKWRX Posted March 11, 2011 Report Share Posted March 11, 2011 I just got a used RH-10 (M100) for $50 off craigslist. Unit looks to be in decent shape, just some pry marks where it looks like someone forced the door open at some point. The battery didn't work and there was no charger. It powered up through USB. I went to Radio Shack and the had an 3v AC adapter on clearance or $3. After cleaning the battery contacts good, the battery holds a charge for about 3 hours of playback. I've already ordered a fresh one as well as the AA battery holder. BUT, now I've discovered another problem. While the unit is on, if I squeeze lightly on either left corner, near when the disc comes out, the unit reboots. This won't work for recording concerts if I have to worry about a little nudge or squeeze powering of the unit during recording. Are there any adjustments I can make to the hinge or any contact switches inside that detects when the door is oped or closed? I have a feeling whoever forced open the door may have damaged or loosed up something. Do any other RH-10 owners notice any "play" in the door if they squeeze it while closed? Any ideas?

sfbp Posted March 11, 2011 Report Share Posted March 11, 2011 No (to noticing this), but I am sure there is a door-detecting microswitch. It may be as simple as fixing it. Quote Link to comment Share on other sites More sharing options...
netmduser Posted March 11, 2011 Report Share Posted March 11, 2011 I had similar issues how did you clean the contacts? Suggest to clean them up with alcohol and q tips both terminals. Quote Link to comment Share on other sites More sharing options...
Azureal Posted March 12, 2011 Report Share Posted March 12, 2011 I just checked mine for play in the closed door with a disc present and there is a very, very small amount of play, the door moves ever so slightly, but no reset of the unit.

sfbp Posted March 13, 2011 Report Share Posted March 13, 2011 I think you have to get it disassembled and find the microswitch. It (or the metal which triggers it on closing) probably got bent when someone prised the unit open. If you are not good with tiny screws and the like, most likely a competent service engineer can fix this. But it may cost you as much as you've already spent with no guarantee of success. It's S893 in the manual, I have a feeling it's at the corner under the Walkman symbol located on the lid of the unit. Quote Link to comment Share on other sites More sharing options...
NickyJay Posted March 15, 2011 Report Share Posted March 15, 2011 Perhaps on a related note: the newer models are not built to last. My older Sony MD units are still going strong- all metal casing baby, no plastic anywhere. Quote Link to comment Share on other sites More sharing options...
sfbp Posted March 15, 2011 Report Share Posted March 15, 2011 Fair enough, but the part that's bent is (in all fairness) probably metal. Stephen Quote Link to comment Share on other sites More sharing options...
TEKWRX Posted March 29, 2011 Author Report Share Posted March 29, 2011 Well, I think I figured this out. There is a metal tab that is underneath the lid between the headphone port and the mic port. This tab must press the switch that tells the unit the lid is opened. I just bent this tab ever so slightly and it seems like it's making good enough contact now. So far I haven't gotten it to re-boot. I hope thats all it was... Quote Link to comment Share on other sites More sharing options...
sfbp Posted March 29, 2011 Report Share Posted March 29, 2011 Sigh. Guess I had the picture upside down in my head, but you found it anyway. Well done. Quote Link to comment Share on other sites More sharing options...
