Power supply still putting out 14 volts dc. Tried pushing on button
really hard. Also tried to find info on web for disassembly searching
in google with the words disassemble and disassembly and this model
name. Nothing! No luck so far!

Basically, you insert a paint scraper/putty knife into the slot between the
two screen halves and pry it apart. The service manual shows the steps.

I was going to repair mine but did manage to get it back on (6 months ago)
and have never turned it off since.
