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).
