To view the pictures on the computer, remove the card from the battery compartment and put it in a card reader connected to your computer.

Only for the brave, on a warrenty expired camera.
Buy a set of jeweller's screwdrivers.
Make sure it is off, with the lens retracted, and remove the battery and SD card.
Remove the 11 screws holding it together
The metal shell is in two halves that can be pulled apart. The rubber socket cover flap has to be removed once one half is off. A rubber gasket round the eypiece lens may drop off - it is easily replaced.
Hold the inner chassis by the edges.
The lcd screen is held by one screw, half hidden under the wiring to the flash - remove it.
Push the wiring to one side just sufficiently to enable you to hinge the lcd screen up on its flexible printed circuit wiring loom.
Underneath you will see the back of the ccd pod, with a flexibe printed circuit wiring loom pinioned under a metal plate with two Y shaped holes filled with brown gunk, and held down by a torex screw locked with some holt melt adhesive, and two further screws inaccessible under the metal chassis to the right.
I hypothesised these were the contacts that become detatched in hot conditions, and (1) tried to shift the flexible printed circuit minutely from side to side using the hole in it (it didn't move appreciably)and (2) pressed down quite hard in the centre of the metal plate, having supported the chassis from below so as not to damage the lens.
I reassembled the whole thing and it worked immediately, with just a faint light smear down the left hand side of the image (the whole image had been completely smeared, then dark, before) which was only noticeable when photographing in dark conditions.
So I took a gamble and it seems to have worked. If it hadn't I was going to break the glue seal on the Torex screw and unscrew and then screw it up again.
Obviously doing this is on your own responsibility.
