I have a lightly used A6000, and over the weekend, i was shooting single images with the camera (and screen), mostly on for about an hour,, and the screen started going "black/blank" at times.. It would still fire, but was unable to use screen intermittently; sometimes would turn off, then turn back on at times.. ?? I noticed the same issue today, but camera was only on for a short period of time ?? Any help, appreciated.. Thx, Chris.
