I have opened my camera and found that the flexible circuit/ribbon cable that connects the LCD to the inside of the camera is broken. This is due to poor design, in which the flexible circuit cannot withstand the constant movement of the LCD.
I have managed to buy a new cable from a Sony repair dealer, and will attempt to fit it later on this week.
The part number for the new flexible cable is:
Ref no. 171
1-864-761-11
FP-185 FLEXIBLE BOARD
cost is about 35 dollars
Google for it, or goto your local sony centre and ask them to sell you one.
if you are interested in how I get on with it, you can mail me at airshod@gmail.com
I won't bother trying to complain to Sony directly, because it is quite apparent that they really couldn't give a toss.
-----UPDATE-----
I have now successfully repaired my camera with a new flexible circuit/ribbon cable, and have made some quick notes that can be found here:
