Hi Vwpologt,
welcome to the forum![(Y)]( "thumbs-up")
Have you checked if the internal battery (coin cell, CR2450) is weak? The battery is already sitting in a holder so no soldering is needed in case of replacing it.
Since you don't get anything displayed you can't start the in-built test program to check the battery voltage...
So first of all I suggest to open up the unit, flip the battery out of its holder and measure its voltage - should not be less than - let's say - 2.6V. If in doubt replace it with a fresh battery. Then check if the unit will start properly when switched ON.
If the unit works you can initialize the factory settings by using the test routines:Once the test routines are started you may press [F3] to perform the factory set:Hope it helps.
Let us know how you go on. And let me know if you're in need of the service manual...![8)]( "Cool")
