HI Experts,
I have been using a DN2800MT successfully some time as an on board computer on my boat.
Earlier this year it started to become unreliable. After contacting the supplier and others I have got nowhere.
Firstly, the board is designed to run over a wide voltage range (8-19 VDC) I am using 14.2Volts on a DC-DC regulated PSU.
On occasions the board will not start (when the On -Off button is pressed there is no response!) the power is reaching the motherboard as the green standby LED on the PCB is illuminated. I have tested the power switch and it is fine.
After much head scratching, I find that if I "Power up" and leave the computer in its standby state for a few minutes, it powers up and runs fine, it will even shut down and start up as required, so long as the PSU is not turned off.
I am now totally confused and hoping that someone has come across this fault or can offer some advice.
Regards and Merry Christmas
Nigel
