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 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!
