I have a 105B that has not been used for a couple of years and is unresponsive.  I checked the voltage and the wall wart is working, as is the battery pack.  When I was going through the service manual I found the following and since this is the symptoms I get I wanted to give it a try:

Kernel Test
Start with the Kernel Test if the test tool does not function at all (no display, no beep at power on).
With the Kernel Test the microprocessor and the transmitter/receiver circuit of the optical interface
can be tested.
NOTE: If loading the FlashROM fails, it is possible to get a ScopeMeter test tool which is not
functioning. For example: if the operating system is corrupted, it is not possible to operate the
test tool normally. In this case you can reload the operating software as follows:
- ground test point TP202, and turn on the test tool
- load the operating software into the FlashROMs. For this action you need special
software: contact your nearest Fluke Service Center.
- release the ground from TP202 and perform a MASTER RESET (hold down the F5 key
and turn the test tool on).

I contacted Fluke and they were not sure that the software was still available.  Would this utility reload the operating software?

I'm not sure what do you mean by unresponsive but if it is completely dead you might want to check CMOS chip that generates the standby power for the power button. Mine was dead.

Check this video of a guy having the same problem.

Thank you, could be the same problem.  Unfortunately I don't have another scope to do the investigation with but I will see what I can find.  He has a nice lab to work in, been a long time since I had that level of equipment at my disposal.
