When switching on, battery indicator flashes with outline only, camera not operating. Same thing with new batteries.

In the past I have found that you could clean the battery terminals, both at the bottom of the battery bay and on the battery lid with lighter fluid and a cotton swab and get the camera up and running, but the cleaning fluid needs to be lighter fluid as alcohol didn’t do the trick for me … AND the type of battery is pretty critical too, as regular alkaline batteries do not have sufficient current to do the job, I use the Energizer Ultimate Lithium battery and coat the ends with dielectric grease (just a dab/small amount) … I have had some success using this described method … thank you, good luck … Jim Nickerson, Pentax user and repairer … 8)
