When my OM-D 10 is in "P" mode the flash fires but the pictures are very, very dark, obviously underexposed. What's wrong?

1 - Make sure you don't have your diffuser screen pulled down. This is easy to overlook and will produce that effect.
2 - Reset your flash - hold down the "Mode" and "On/off" button together for a few seconds. This gets you out of any funky mode you could have accidently put yourself in
3 - Put camera in fully auto mode. That clears any weird modes you could have gotten into there
4 - Clean the contacts on the flash and camera. I use a pencil eraser and wipe with alcohol and paper towel. Dirty contacts can cause flash misfire or cause full flash during the preflash mode, which gives you dim or dark photos or sporatic flash operation.

I have 2 SB-800s. When batteries leaked in one Nikon took forever to fix it, so they eventually sent me a refurb. Then they sent my original back. Which was great, until recently it developed this problem.

Another possibly related side effect is the modeling flash does not burst -- it only fires a single (very bright) flash.

The capacitor argument sounds likely. Coincidentally I also had a problem where the flash would fire sporadically -- but that was due to scuz buildup on the contacts.

Sorry I don't have a real solution for you.

charging flash:-
POSSIBLE CAUSE:The camera is recharging the flash.
SOLUTION:It takes longer to charge the flash when the battery is low. If this message appears a lot, replace or recharge the battery.

Ok this is a crappy fix but it works for me.

If your flash isn't syncing correctly make sure your on auto flash. when your flash flips up and you get the beep push the piece that holds the flash just a little forward. and walla your flash syncs up.

defective shutter curtain opening, it needs pro service. Shutters have life expectancy around 5thou to 10 thou shots.

You may need to use the flash. Make sure the setting is not flash off. If you're using the flash, make sure your subject is within the range of 14 feet for wide angle shots or 11 feet for telephoto shots. Use Image Expert to adjust the picture's brightness and contrast. Try adjusting the camera's exposure or sensitivity settings (use the Manual user mode). If you're taking pictures in the Manual user mode, look for the EV! warning that appears on your LCD screen when you are taking pictures out of the ideal exposure range. If you have trouble setting both the aperture and shutter speed manually, try adjusting the aperture and letting the camera choose the shutter speed with Aperture Priority mode. If you're using the macro mode to take a close-up photo, be sure to provide adequate lighting for your subject. If you're taking a picture at night and you want to light up the background as well as your subject, use the camera's slow synchronized flash mode. If you need more light, attach an optional external flash to the camera's hot shoe.

Be sure that you are capturing images in the right shooting mode. For example, if shooting a night scene your image will be underexposed and dark if the image is captured in the Program Auto mode for regular photography, or in any mode other than Night Scene. Be careful that when capturing images, nothing is obstructing the flash.
