Camera displays do give problems, this would not stop you downloading and viewing pictures though. To confirm this take a couple of pictures and view them by downloading them elsewhere.... it it was the processor or some other part of the camera then you won't be able to see tham as well.
With displays, it could be the ribbon cable, it could be tarnished contacts, contact 'creep' caused by the pressureof the retaining bar, the backlights or the display itself..... either way thew camera would have to be stripped down.
Some displays are easy to change, especially those that swivel, it means one being used to handling very small screws of differing lenghts, doing this in a clean environment and being able to handle small connectors.
The best bet is to send it to a Canon agent for a quote, since the SX260 are far better than their latest clones.
