I was trying to find how to replace the CCD lens sensor on the Nikon Coolpix L840

My camera display will work for a bit, but then goes off. Subsequent efforts to start it yield poor results. If I pick it up and try again in a few hours, I may have a short time to work before the screen goes dark. The batteries are new. I think this might be a case of blown capacitors on board, but I could use insight. The motherboard costs more than the camera now.
