So how exactly did you dismantle the H1000 without ruining any of its components? I own a H1000 as well, and the sound is very weak (I figure it's a bad cap). In addition, the card reader doesn't appear to work, so the contacts may require a good cleaning.Success! Took the whole Newton apart, cleaned contacts, sprayed the PCB (front and back) with electronic solvent cleaning spray - fired up first time. Suspect it was either the sliding power switch that wasn't contacting well, or the LCD ribbon cable didn't seem overly snug on the motherboard. It's running NOS 1.10, good times!
Any help would be greatly appreciated.
