I have a DRD420RE which turns on the LED upon applying power and it just stays on but the unit is not functional. The ON/OFF button does nothing. The only buttons that appear to do anything is the reset sequence - INFO + right-arrow.
I have reprogrammed both the eprom and flash but I get the same results (ie. the jtag interface appears to work just fine).
I also tried changing CR14108 but it turns out this rectifier was good anyway (Tried using an NTE588 with the same results).
No visible damage to the board. Any ideas on what might be the problem ?
Thanks
