Originally posted by aerogator My Kx will some times take 5-6 tries to turn on after I flip the power switch on-off repeatedly.
The weird fact is that some times while the screen and power light is on and pushing the shutter button will shoot photos but the screen is off and the text in the viewfinder is off!
I think that those are two separate problems,
both of which (or similar) I have experienced with my two K-x cameras.
If the camera doesn't fire up when you turn the switch,
then it may be a problem with the switch, as others have mentioned,
but it may also be a problem with the batteries making contact with the connections.
Be sure to keep the ends of the batteries clean.
Also, some batteries are a little shorter than others,
and may not make such good contact.
It may help to gently bend the contacts so that they press harder on the ends of the batteries.
The other problem shows up in one of my five-year old K-x cameras.
After some use, the screen will stop displaying.
There may be some separation of the rear cover,
so you might try pressing the surround of the screen and back panel.
Ultimately, these K-x cameras have already lasted longer
than we should normally expect for electronic equipment.
You can get a new K-50 for around $300 now,
and with the adapter, it can use the AA batteries.
So it may be time for an upgrade,
if you need your camera to be fully reliable.
