The LCD image screen on my Canon A620 has quit working. I am unable to set the functions or use the menu. Is there a fix for this? I had the screen disassembled and there appeared to be a small battery on the PCB however I can not find any information on this at all!
Connie Eisenhour, the battery is a 3V lithium-ion battery, Canon part number WK1-5132-000 (MS614FS micro battery). It is your CMOS battery and should not be related to your LCD. Check the fuses on your board for continuity, I believe that one of them is your backlight fuse. If both show continuity, I would suggest that you replace the LCD for any further trouble shooting. Hope this helps, good luck.
