Melvin George II Posted October 14, 2009 Report Share Posted October 14, 2009 Before I send my MZ-RH1 in for repairs, does any one have any insight to what makes the unit shut off while recording a show with the external mic plugged in. I got it in '07 and have performed about 250 shows and now in the middle of the set, it just shuts off! any ideas, anyone? Quote Link to comment Share on other sites More sharing options...

Avrin Posted October 28, 2009 Report Share Posted October 28, 2009 Oxidized and/or loose contacts/screws, most probably. Quote Link to comment Share on other sites More sharing options...

sfbp Posted October 28, 2009 Report Share Posted October 28, 2009 There's two screws on the bottom,two on the "back", four on the moveable lid (only two of which are accessible without some disassembly), and one more accessible only after you remove the battery door (removing this door is the most frightening moment as you worry you broke your baby forever). The two on the bottom, nearest what Sony calls the "Cabinet" (the black plastic thing that contains the OLED), seem to be the most problematical. From my limited research you can have them too loose or too tight, though the latter is likely to be after an attempt to fix the former (LOL). I had the famous "glitch when using jog lever" problem until very recently, when in an uncompleted attempt to get the whole thing apart (there's no indication how to get the darned bottom segment over the USB connector) I discovered that mechanical operation of the RH1 is critically dependent on the tightness of these two screws. Particularly the jog lever and the open button. By the time I got it back together and loosened off the one nearest to the open button so that it didn't stick (ugh!), the jog lever had fixed itself. So am guessing that my problem, and yours too, are inherently mechanical in nature. If you *do* attempt removal as per the service manual, be advised that the two black plastic strips on the left and right of the unit are fragile and unstable, and the one which the battery door clips out of, appears to have excess plastic moulding of a very fragile-looking nature. Excess meaning that it has no useful function, and may even be the root of all the problems reported. Mine no longer does have this excess moulding PLEASE don't take my word for it - this is tricky stuff and I will not be responsible for your disaster..

Melvin George II Posted October 28, 2009 Author Report Share Posted October 28, 2009 Thank you everyone. I took it in for repairs since it was still under warranty and the guy said since I hadn't purchased a new battery since I bought it, I should replace it and see if that solves the issue. Unfortunately, I had to leave to tour the Caribbian before the battery arrived. I will share your posts with the tech guy if the new battery is not the fix.I'll keep you posted. Thanks again.
