D300 Problem
-
Hopefully someone can help here?
When my D300 goes into standby it wont come back out. Tapping the shutter release does nothing. The only thing I can do is turn it off and on again. I tried updating the firmware but no good.
This started after I put on an SB800. At first there was communication, the flash could read iso 200 etc. Then the flash started going into standby while I was fiddling with camera settings. When I turned it on again it read iso 100 and never worked.
The flash is ok because it worked fine on a D80 soon after. The D300 isn’t.
Any ideas please?
I vaguely remember hearing something similar happening some Nikon SLR’s and AFAIK it was due to the contacts in the lens mount, give them a clean and same for your lenses and see how that goes. Strange that the SB-800 is causing problems, I know the hotshoe on my D200 was never fully right and would often lose comms and trigger the flash erratically at times but only intermittently.
There’s also a custom setting about waking up the meter, ie. if the shutter release or the AF-ON button or both wakes up the meter, dont have the manual for the D300 anymore but could be worth a look too. Are you using official Nikon batteries?
Hi Cian,
Im using Nikon batteries. I tried 3 lenses so maybe its the contacts in the lens mount. It seems unlikely that the lens mount and the hot shoe both need a clean today. This was the first time I put the flash on the camera. I will look more closely in the manual for wake up settings too.
Thanks.
There’s some wierd circuitry in the Nikon slr’s, seems like the power is routed in a serial arrangement around the various interfaces so a problem with one will cause wierd behaviour in another. I could be wrong, haven’t time to study wiring diagrams!
Worst case scenario would be that the chips that store the firmware is probably corrupted. If it’s still in warranty, send it off to get repaired.
It’s probably something simple though if it still works when not in standby. Did you reset it to factory settings? A friend of mine’s D200 went odd on her, the light meter went extremely inaccurate and it stopped autofocusing. Resetted it to factory defaults and it was fine.
3 hours of research, a break for a few pints, I sat down to give the hotshoe a clean with an eraser, pressed the fn button by accident and it woke up. It might be ok.
My research told me that a good clean with something like deoxit will fix most problems. The main problem people have seems to be a false empty battery reading leading to shutdown. Usually this happens with bigger lenses.
Cian: Id say you are right, it is weird. I dont know what happened to it or how it sorted itself out. A problem with one thing causing weird things to happen in another.. definately.
shleed: factory defaults did nothing either. If cleaning doesnt sort it then I will have to go down the road of sending it off. Most peoples problems are intermittent and Nikon often respond with “cant replicate problem” Anyway, it seems I might not have to go there.
Thanks
