You need to eliminate the possibility that one of the Sony cells is bad, which is quite likely with NiMH cells, especially if they are not used very often. Just get a pack of four alkaline cells and see if that fixes it. If it does, replace the Sony cells with Sanyo Eneloop or equivalent.

...or just keep using fresh alkaline batteries. Rechargeable ones are far too much od a slitter for me. Much easier to carry a spare pack of normal ones.

Eneloops consistently outperform alkalines. They hold their charge extremely well and give a much more consistent cycle time over the life of the charge than alkalines. Alkalines have significantly higher internal resistance than Eneloops, so despite the higher initial voltage are unable to provide a high enough current to give short recycle times. Tests show an initial flash cycle time nearly 25% slower with alkalines, while by the time you've nearly exhausted the cells the gap has widened to nearly 50% as the on-load voltage drops off quite badly.

Oh dear! It does sound like there's a problem with the flash then. Unless it's still under warranty it would most likely cost more to repair than a new unit, at least in the UK.
