as a follow up to my recommendation about 'tapping' the camera to correct the pinkish and purple washout colors, let me add this.
Recently, with a power outage, ( this of course happens now and then) my camera returned to the washed out colors. In the past the tapping worked to return normal colors, this time, no go.
After tapping all over for 5 minutes with no results, I had the idea to have my wife sit at the computer and switch back and forth between night and day mode every 3-5 seconds while I tapped with a knife handle. Success in under a minute ! Normal colors back.
Also, I might add under normal use I leave it set for 'always daytime mode' to avoid problems.
