Olympus C700 - Progress at last!
Looks like we're making progress -- thanks to that real nice feller who
posted and suggested I try using the camera with an AC adapter. [Note to the "try a new battery" crowd: No, it wasn't the batteries.] I picked up an adapter at Frys Electronics for $19.99. I saw some on ebay and elsewhere online cheaper, but by the time you add the $5-10 "shipping and handling" and wonder what kind of adapter you're "really" going to get and when.... I thought this one was the best choice. And it's a universal job - all kinds of voltages, and current up to 2500 mA, so that's fine for the C700 and my other junk too. First I tried the camera as is - that is on good (new) alkaline batteries only - to be sure that it was giving the same problem. Sure enough, same problem - one shot or moving the zoom lever and "battery bad" message pops up. Then I plugged the AC adapter into it and first time every time, the camera works again, just like it's supposed to, time after time, zoom in, zoom out, click, click, click, click, click.... Then I removed the AC adapter and used it with the same batteries only again and it worked every time, zooms in/out, etc. just fine and no battery bad message. Someone also said that there might be charging problem -- might be it. May be still a partially open circuit, bad solder joint or failing component somewhere between the batteries and the power circuit. AC adapter may have temporarily charged up capacitors enough to get a few shots from the battery-only. Time will tell -- will see how many photos I get out of a new set of batteries and report back. Thanks again to all for all the dozen of constructive help! It took several months, but saved me $155 in repair charges and I gain a great deal of knowledge about how these things work. And a special thanks to all the whiners, complainers, know-it-alls and the "just buy another one" boys. Without your endless jabs and ignorant comments, I probably would've dropped this months ago! B^) Fred |

Now back to an update... After using the AC adapter for awhile, I disconnected it and then ran it on batteries only. This time I took 4 or 5 photos before the "battery low" warning came back up. Then plugged back in with the adapter and it work fully again. Probably not a revelation to the more advance folks, like David, but I like to double check things before pulling out the chain saws.

Just curious..... what is, or was, the milli/amp rating of the batteries
that seemed to fail ? The AC adapter you found puts out a lot more amps than a same voltage AC transformer for a phone or whatever. Glad you're gaining on the problem......

Even thought the solution seems to have been simple, getting there was not. There are lots of people here who understand and appreciate that. If I ever have such a problem with my camera I hope I can remember to just push a matching plug into it's adaptor jack a few times to see if that helps. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |

Thanks for the good words, Jim! It's just a hobby camera and so I'm not in
a hurry to get if fixed or dish out a couple hundred $$. More fun for me to diagnose it and hopefully fix the blasted thing .... and pass along what I find out. After a few plugging/unplugging, turns out there's no oxide build up on the AC receptacle. Dang it, that would've been too much to ask! "Jim Adney" wrote in message ...

Dang it, that would've been too much to ask! Hi... Dunno how much it matters, if at all... but not on the ac receptacle. Rather, there's a switch as part of that jack. When you insert your plug, it physically pushes the switch open, breaking the connection between the battery set and the camera. So that the batteries and ac adapter aren't paralleled. Naturally it follows that when you remove the plug, the "switch" returns to its resting position, so that the batteries are once again connected to the camera. If you have a stereo and/or headphone set you'll get the principle... plug in the headphones and the speakers disconnect; remove the plug and the speakers are again connected. You might try inserting and removing it many times, slowly. Perhaps rotating the plug a little while it's inserted. I really, really hope that you don't even think about dis-assembling your camera. Really. So, if all else fails, you might try just a single puff of contact cleaner. That jack is an enclosed assembly, spraying into it won't be spraying into the camera unless you "drown" it. So, you might pick up a spray can of contact cleaner (in Canada anyway, Radio Shack, about $10 CDN). Then holding the camera so the jack is down, give it just a single puff into that jack. A tiny, tiny amount, a fraction of a second spray. And continuing to hold it jack down, immediately insert and remove the plug over and over. If the plug is at fault, this should clean it up. Leave it air dry overnight, propped somehow so it rests plug down. On a sheet of newspaper just in case. I'm writing from photo.digital, perhaps the sci.electronics guys will have better/more advice. Take care, and all the best in the new year. Ken |

give the spray treatment a try. Specially thanks for the safety warning. And Happy New Year! Fred "Ken Weitzel" wrote in message news:txLAd.618878$%k.493377@pd7tw2no...

I'd be a good deal more concerned about the camera itself, than my eyes. Really, we've been spraying contact cleaner and other aerosols for years. Surely we can do it safely. OTOH, there are gears and optics inside there. Get some of that stuff on there, and results are unpredictable at best. I'd take the damn thing apart...damn the torpedoes. Use a maginfier light, work slowly, carefully. Take pictures (with another camera of course...maybe video) of the disassembly. Digicams are difficult, but not impossible, to successfully R&R. If I can do my Coolpix--much smaller, I believe than the Oly--he should be able to dismantle enough to protect the rest of the camera from overspray when cleaning the power jack. Still, just cycling the power connector in and out may be all it needs..... jak Ken |

I took a few photos with the help of the AC adapter. Then unplugged the adapter. Turned on the camera and the zoom starting cycling out 1/2-inch, then back in 1/2-inch, back and forth.... The power switch had no effect on it. Had to open the battery door and break the connection to stop the cycling. Am I on candid camera??! Fred |

Looking back, I don't think I was clear on my suggested failure mode.

It's just possible that they used this contact to provide power in the absence of the adaptor, but if the contact got resistive, then this "resistor" would be in series with your batteries, and would make them look discharged. Just inserting the AC adaptor plug a few times, or maybe just once, would have exercised this contact and broken thru the insulating oxide layer, fixing your problem. I don't know how realistic it is, but at least it fits your observations. If I'm right, you don't have to do anything else for a few more years. Then, when you have the problem again, just insert the AC adaptor plug in the camera jack a few times and you should get a fresh start. I wouldn't do ANYTHING else. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |

Thanks, Jim. I did try this - several times, and have since plugged the
adapter in and out many times taking photos using it. Still the same problem with the camera not recognizing good batteries thought. Thanks - appreciate the advice.

Earlier you wrote: Then I removed the AC adapter and used it with the same batteries only again and it worked every time, zooms in/out, etc. just fine and no battery bad message. I took this to mean that the problem had gone away. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |

Fred Sounds like your voltage regulator circuit has a bad component such as a leaky capacitor or defective zener diode. PJ |

Actually, in this case, it turned out to be something simpler - the adapter/battery switch in the ac adapter plug on the camera had an oxided coated on it. A little exercise and it wore the oxide off. |

"Fred" wrote in message news:nnmAd.19488$rL3.1622@trnddc03... Looks like we're making progress -- thanks to that real nice feller who posted and suggested I try using the camera with an AC adapter. [Note to the "try a new battery" crowd: No, it wasn't the batteries.] I picked up an adapter at Frys Electronics for $19.99. I saw some on ebay and elsewhere online cheaper, but by the time you add the $5-10 "shipping and handling" and wonder what kind of adapter you're "really" going to get and when.... I thought this one was the best choice. And it's a universal job - all kinds of voltages, and current up to 2500 mA, so that's fine for the C700 and my other junk too. First I tried the camera as is - that is on good (new) alkaline batteries only - to be sure that it was giving the same problem. Sure enough, same problem - one shot or moving the zoom lever and "battery bad" message pops up. Then I plugged the AC adapter into it and first time every time, the camera works again, just like it's supposed to, time after time, zoom in, zoom out, click, click, click, click, click.... Then I removed the AC adapter and used it with the same batteries only again and it worked every time, zooms in/out, etc. just fine and no battery bad message. Someone also said that there might be charging problem -- might be it. May be still a partially open circuit, bad solder joint or failing component somewhere between the batteries and the power circuit. AC adapter may have temporarily charged up capacitors enough to get a few shots from the battery-only. Time will tell -- will see how many photos I get out of a new set of batteries and report back. Thanks again to all for all the dozen of constructive help! It took several months, but saved me $155 in repair charges and I gain a great deal of knowledge about how these things work. And a special thanks to all the whiners, complainers, know-it-alls and the "just buy another one" boys. Without your endless jabs and ignorant comments, I probably would've dropped this months ago!
