Hi there Mark and welcome
Can you please remove the power to the digisender (so unplug it from the power socket).
Then wait 10 minutes, connect the power again to the unit, turn it on and tell me please if it is now operating correctly.
Let me know the results please
It is the internal power supply or mainboard that has faulted. It will be a or blown or buldging capacitor
I am really sorry about this and you are going to have to return the unit to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
