Received a Canon SD1000 from a relative who had not used it for a long
time but said it wouldn't work right, they thought I might get some
use out of it. The body of the camera is in mint condition, I was
amazed as it looks like it's never been used. The camera functions
fine as far as power on and off, lens extend and retract, and shutter
button snapping pictures, but the rear display is solid gray with some
barely visible horizontal lines. No menu items or text, just blank
display.

When I take pictures (guessing as I have a blank screen) and download
the files from the SD card to my PC, the are valid JPEG files but are
just colorful vertical lines with a few horizontal lines like this
example :

Would like to recover this camera as it's a nice unit and looks new.
Been in touch with Canon and they are offering a Customer Appreciation
program to trade it in and buy a factory refurbished unit, but I kind
of like this one if I can salvage it.

Not sure if it could be something like a loose connection in the
camera or maybe something like that.

Thanks in advance for your assistance
