Greetings! My H24005 has stopped working and before I started disassembly I thought I would see if there were any suggestions.
Thinks were running fine, putting out 14V at about 20mA connected to a recalcitrant charging circuit. As so often happens, work rudely interfered. I was away for about 15 minutes. I found my power supply with a blank screen. I powered it off, turned it back on, and the backlight on the LCD flashes once and then thinks looked like there was no power.
I plugged the USB into my computer and the Arduino failed to appear. Took the cover off, powered up, and the two lights on the USB connector side of the Arduino were on. I thought it might be the Due, so I unseated it. Looks like the Due is fine. I upgraded the firmware to 1.1.1 while it was out. Reseated the Due, powered up, and the same behavior. When I power up and switch off standby, the LCD backlight flashes briefly (.25 secondish) and then the system appears dead except for the two lights that are on the Due.
I did measure 3.6 volts on pins 22 and 23 of the Arduino, other than that, I have not poked further. My next step is to pull the front panel off, but before I start that, I wanted to check if anyone had a different suggestion.
Thanks.
