Don't worry about lethal voltages, those are low voltage devices.

Hmm. Combined into the power supply is a separate component that
provides power to the lamp. It has a box mounted on the IC with two
serious wires coming out of it.. and on the box itself it has a
warning and a 25kV output label.

Also on the main part of the PS itself is (what I believe to be) a
capacitor that is about an inch thich and 2 inches long. I haven't
investigated to see any numbers on the side yet.. but I was wary.

Are you sure this is a low voltage device?

It may well be worth fixing if you have the time. It could be a bad
regulator or transformer winding. Check the AC voltages at the all the
secondary points of the power supply transformer. It may only have one
voltage line problem that could be repaired or hacked. If you need to
determine the correct voltage for a suspicious voltage reading, then
check the datasheets on the ic's that use the voltage further down the
circuit path.

Alright, thanks for the info Kyle. I'm going to read up more on power
supplies so that I can hopefully figure out where the regulator and
transformers are on my device.

Thanks,
Dylan
