My FG has recently started playing up. The led display in the viewfinder which displays the shutter speed seems to work ok, but in addition to the selected speed the led for 1 second is lit, and is about twice as bright as normal. It's so bright it half lights up the 1/2 second window next to it.

Any idea's on where to start?

Mike ... there are all sorts of posibilities but your first move should be to change the ASA to a different setting. Move it significantly away from the currently set number. Now test the metering again.

You are effectively trying to eliminate or confirm that the problem is (or is not) at the ASA wiper or the circular segmented resistor as under the film rewing knob beneath the top-plate.

If all is good at a different ASA setting, you may only need to clean the resistance track and clean and check the spring tension of the gold-plated wiper.

If all remains good at the different ASA setting but still bad at the original ASA setting after the cleaning job - then the chances are the circular segmented resistor is bad at a particular spot. In this case you can easily replace it provided you can obtain a spare (perhaps from a junker camera of the same model) - or you can use the closest ASA setting which works - and make a compensating shutter-speed or ÄStop adjustment.

I have encountered your described problem on FG Models and the above guideline is valid.

Thanks for the info, Stuart. It's early days, and I don't want to tempt fate, but I think I've fixed it. After changing lenses and finding the same problem, I guessed it must be the ASA dial or the f-stop resistor under the lens mount. This is simply because tapping the ASA dial side of the camera got it to go away, tapping the shutter speed side didn't, otherwise I'd have suspected the shutter speed dial as well. I cleaned the gold contacts and wipers, reassembled, and so far, so good.

I was getting a bit desperate the other day, so got a quote from a camera repairer. £95 + VAT (@17.5%). That makes me feel even better...

Ah! I only charge £90 for advices in this forum.
So you are £5 ahead of the game - and no VAT ;- )))))))))))))))))
