First I'd start with a set of new batteries. Make sure bottom cover screws
are tight.

> It's not often I come up with anything on-topic here, so I hope you all

> then for the sake of my poor, sick OM-4 !!
>
> I moved house last October, and to be honest the cameras haven't been
> out of their cases since. Life has been hectic, and I just haven't had
> the time. Anyway, the nice weather is upon us again (well, except today
> !) so I thought I'd get out and take some pictures. My OM-4 has been
> sitting with a roll of nearly-finished Velvia 50 in it since the end of
> last September, so I thought I'd finish it off. Only 4 shots or so
> left, and my girlfriend wants to borrow it at the weekend.

> seems strangely blank. I mean, the picture is there - but no display at
> the bottom. It's been a while, so I assume it's just me being daft.
> Then I rotate the dial to the battery check position. Nothing.
>
> OK, new batteries. I'm sure I had some around here somewhere. Oh.
> Wait. I put them in another camera .. !
>
> To cut a long story short (oops, too late !), I tried the batteries from
> my OM-10 in the OM-4. Nothing. These batteries power up both my OM-10
> and OM-2n fine, but the OM-4 stubbornly refuses to respond.
>
> I have the "later" model which turns off after 30 seconds or so if you
> leave it on battery check. It also has the silver battery and MD
> covers, despite being a black body (so I assume it isn't a paint problem
> restricting the contact). I've wiggled the little spring, and it seems
> fine (the contact at the bottom of the battery well). No corrosion that
> I can see.
>
> So, does anyone have any ideas ? Obviously, I will get some fresh
> batteries tomorrow and check everything again. But I'd appreciate any
> hints on what to check. I'm not averse to opening up the beast if needs
> be (I'm pretty good at working on miniature electronics work - it's part
> of my job; mechanics not quite so much so !). I seem to remember talk
> of a common loose wire under the bottom cover ?
>
> I assume that removal of the bottom cover would expose the film ? If so
> I'll just sacrifice the last 4 shots (or go "Red 60" and take a few -
> this will work, right ?).

> Right, plenty of questions. Thanks loads if anyone (or everyone !) can
> help.
