My DMR-EH50 doesn't power up - display panel is completely dark. I did remove the cover and some DC voltages are present but depressing the power-on switch doesn't do anything. Any suggestions? Thank you.
Sounds like a hardware problem. Best bet is to find an authorized repair center. Could be something as simple as a bad switch, but could also be one of any number of different problems…and will be hard to find without proper equipment and training.
