Olympus PEN E-P5: problems with touchscreen

Sounds like a real fault, cracked ribbon cable or something deeper. Send for repair is the only option.

Thanks Guy! I'm not sure, whether it is a hardware damage or rather a software failure. When the touchscreen works, the failure never occurs during the operating camera/shooting process. Only after turning on the camera. And as I mentioned before, tilting the camera or the touchscreen has, so far, no effect on that misbehavior.

I don't not, if this is a real workaround: Yesterday evening, before turning off the camera, I switched from focussing-mode by touch-selection to the camera's auto-focus-detection mode. Doing that several times, the touchscreen showed up no failure!

What I noticed: Without that workaround, that means letting the camera turning off with touchscreen-focus selection activated, turning it on again and the touchscreen again doesn't work, the camera doesn't show an initial focus-peaking. I mean, normally when I turn on the camera, the camera directly focusses right at that part of the image/display, where it has been set to in the previous state. This is indicated by the green rectangle on the screen, which flashes up for 1 or 2 seconds when you turn on the camera. When I turn on the camera and that green focus-rectangle does not appear, I already know, that the touchscreen won't work. So, perhaps there is a link between touchscreen-failure and initial focussing during the start-process of the camera?!

Curious. When I turn on there is never any initial green focus rectangle showing for that one or two seconds as you describe. What mode, what lens and what settings? If I can copy them and see what happens here.

But weirdness like that points to firmware corruption or a memory fault, still sounds like a back to repair job. But the fault needs to 100% repeatable and carefully described or documented or a YouTube video made of what you see for them to find the fault at all.
