HP Photosmart R967 memory card is locked...

Try formatting the card in the camera if that doesn't work try formatting the card in your computer.

actually the moisture must have entered the leads of the display...

the leads should be removed and then it should be dried so take the moisture off..

better take it to a service centre..it is risk to manually operate the sensitive parts inside and you could end up damaging the display

It is likely the battery is not making contact properly or is not getting fully charged.
Check the instructions on battery connection on page 9 and confirm the lights are blinking correctly to show battery is charging.

Take the memory card out of the camera and look at it. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.

The R967 uses standard SD cards. You should be able to purchase them at any department, electronics, or office-supply store. You may also see them at many drugstores and supermarkets.

Sign in to ebay auction, type and click onto digital camera parts and buy a nonworking camera like yous for parts.

Move the slide switch on the side of the card.

No, it won't work unless HP provides a firmware update. Hp has two websites that mention what type of sd cards are compatible with your camera. One says it is and the other says it isn't. I have a HP R967, which is similar to yours. I bought an HP sdhc card from a HP website that said both our cameras could use it. I own several of this model camera, (I bought 3 to give as gifts) and the sdhc causes the cameras to display 'wrong format.' I suggest calling HP's headquarters and asking them to provide a firmware update similar to the one that HP offered for the HP M537 camera and that Casio offered for their older cameras to let them use this type card, which is what I've been doing.

Please try to format your card on computer and then use it....

It sounds as if either the file allocation table or some data on the card has become corrupted.

Have you got access to another camera (friends or family) that you could try it in?

Have you got a card reader on your PC? If so, you should be able to re-format the card using Windows. (Go to My Computer, right-click on the card reader icon and select format)

Hopefully this will cure the problem. If not, you should be able to change it if it is new.
