Default Nikon D80 flash bulb - replacing

The bulb on the pop-up flash unit has blown. I've got a replacement
from eBay (aka China). However is there service manual or website
online that can tell me how to fit this - especially without getting
a
shock from any charged capacitors? Many thanks. Chris B.


This is a case where you should have x-posted or single-posted but not
multi-posted.

Repeating my other reply:

Most recent (20 years) camera strobe circuits include a high resistance
resistor in parallel with the cap to discharge it continuously once
power is removed. That said - do take precautions.

If possible connect a 10,000 ohm 10W resistor across the strobe
connection and leave it there for a couple hours. That should deplete
it. (Batteries out, of course). More aggressive discharge with a pure
short will create quite a snap - wear glasses).

(note that the cap and the strobe are in parallel, so putting the
resistor across there or in lieu of the strobe is the same as across the
cap).

(You can measure the voltage with a simple volt meter as well - set it
to 1000V or so - try to use one hand only).
