I have the same problem with my Power Shot A620, 7.1 MP, s/n is: 0926105205. . No LCD. Camera works fine through view finder. The CMOS battery measured good. Not sure what PCB view was shown on this post but my schematic looks nothing like that. Could find no fuses. Any idea what replacing the LCD would cost? Probably cheaper to buy a new small camera . Is that the view of the PCB on the LCD or is it from the camera body? I am a retired Electronic Technician. Any idea what a replacement LCD would cost?
Pete Chisteckoff post an image of your logic board (front and back) with your answer (actually a question)so we can see what you see. LCD’s for this camera are around $25USD at places like ebay :-( etc. Update (12/16/2015) Use these guides to work on your camera. Here is an image of where to find the board.
You’ll find the fuses on the underside (primary side) of this board. Here is the image about the fuses
As for buying a camera, this should be strictly based on what your needs are. All of the manufacturers have decent cameras as well as a few lemons. I’ve used my HP for 10years without any issues and a Nikon Coolpix S60 for a few years without any issues. Again, this is personal preference.
