I have a G15 which suddenly stopped turning on. If you hold the power button down it does turn on and presents the setup scree to set date and time etc. But you can't do anything because as soon as you let go of the powerbutton it just turns off. Anybody else had the same issue and know what to do to resolve it? Canon want $200 just to look at it!!!

Seems like you dont have any other options but service, maybe from a local shop might be less expensive.
What is the condition of your battery ? Although if it were weak or defective I doubt it would even turn on...it seems to me there is an internal problem in the power circuitry...many reasons that could do that and all require service.

Canon replaced a broken LCD screen on my G15 for less than $200. I seriously doubt that they want $200 for diagnostics. Better check that.
As for the "power on" not working.
Check the battery for damage or dirty contacts.
Check the battery door for damage.
Check the body, It could have sustained damage in a fall or having been submerged in water.
Connect it to a computer with the USB cord and see if it takes a charge or can be powered on. (An external charger might show full charge but not be actually providing one.)
Good luck.

Before you give up and if by not turning it off and removing the battery did not damage an internal component you might be able to find some you tube videos on how to remove the covers, its not hard and just keep track of the screws and where they went. After you have removed most of the covers, battery compartment open etc blow it out with compressed air to get any heavy moisture out then place it in a bag with a good dessicant not rice...the kind you heat up first. What do u have to lose, some time maybe and the cost of a good dessicant. Also to clean anything inside like the circuit boards or FPC's as they are called of any salt water residue use a good-safe spray like Deoxit 5. That will not damage any plastics or rubber...just be careful not to get it inside the lens that goes for blowing the compressed air too..dont blow any moisture towards the lens.
Also you can sell it as is, for parts only on auction sites.

PROBLEM SOLVED!
took the back casing off, and disconnected the cable to the control pad (the thumb wheel) and reconnected it with tweezers, because it's very hard to get into it, and now it turns on, and stays on.
the other problem was that the date/time setting screen kept resetting everytime the camera turned off and back on again, that also has gone away.
the only problem persisting, and still a major one for me, is that when flash is enabled, the shutter won't fire, in other words, i can take photos, without flash, but as soon as i enable the flash via the right D-pad, and flip up the flash, it won't capture.
anyone have any ideas??

That flash problem sounds like it could be several things
the fuse has blown that supplies the DC to the flash board
the connection from the battery box to the flash board is loose
the capacitor on the flash board is bad
the flash board itself is faulty.
The camera will not shoot until it senses the flash is charged and ready.

It's the internal battery. Replace it and the camera will turn on again.
