MZ-50 internal FLASH broken

Hi,

The integral flash on my MZ-50 has recently stopped working.

After taking a few shots using a cable release, the flash went off of it's own accord and hasn't worked since.

I've been quoted £85 for a basic service for the camera, cost of repair on top of that ....

As a stop gap I'm using a cheap non-dedicated flash (£16). I've no experience of using these so I think I've got a bit of experimenting to do. The integral flash made everything so easy!

Can anyone shed some light (pun intended) on what might have happened to the integral flash please? Any suggestions of a cheaper repair also greatly appreciated!

Thanks

Darron
