Keeps saying to power on and off - Sony Cyber-shot DSC-H2 Digital Camera

You found the right place right time buddy.. i know a lot of websites for repairs and manuals that can really help u..

TRy removing the DC power to the answering machine and re connect DC and power it back on. I am assuming it says no messages but tells callers memory is full.

This is because the monitor's Power Button Lockout function is enabled. Press and hold the Power button for 10 seconds to unlock the Power button function. Your sleep problem should also be related to the lockout issue.

press call butnon

You might try removing the battery for a minute or two to reset the camera. You may lose any special settings in the process. After reinstalling the battery, try turning the power on and off again.

there is a button on the gear shift that says hold that may have been pushed in...good luck

Hold down on and + button together for a while, that will reset all.

I'm an English guy with the same problem... What you do is keep the power on for a long time, or you charge it up with the charger. Trust me. However, it is very rare for this to occur. There should be a message saying: "Temperature is too low, keep power on." There should be another message reading: "Turn off power and turn on again to check if camera is fully-functional. Thanks for giving me something to do while X-Plane downloads on my Mac OS X.

Your power cord is cutting in and out. You either have a bad power cord or there is something wrong with the connection to the cigarette lighter. When the unit say "Running on battery - will turn off in 30 seconds" this mean that it has lost external power. This is by design so that when you shut off the engine external power is cut to the unit and that it will shut down.

It a shame that for the C330 Garmin decided to remove the LED light from the power cord that shows the power cord is connected correctly to the cigarette lighter.
