Paul, not sure if you already fund a solution. On step 8 you see a baby spring top left for the on-off toggle slider button. Unfortunately my flash is currently assembled. Does that little spring look like that? Sort of like from a ball pen except smaller? Good luck!

As components sometimes blow out due to another component being shortened out this might be tricky. I would never recommend trying this as there is A LOT of voltage in this flash. You might find a "dead" flash on eBay with this board in tact?

Try to get a screwdriver that is long and big enough in order to avoid stripping the head. You should also get enough leverage this way. You might want to take a trip to the tools store with the flash.

Yes. Capacitors will have that effect. always be carefull and wear eye protection and possibly isolating gloves. You would need lots more amps to cause serious harm but the unexpected flash gets your attention.

Did you find out what went wrong with step 9?

You are very welcome. I like to see other very bold people out there fixing stuff!

Was able to peel the ribbons without removing the battery. Worked great with a 3G. Thanks
