Cisco TelePresence Touch 8" showing a vertical bright line end to end on the screen

I will also try to do a factory reset of the unit, but have you stumpled on something like this:

Hello,

I have seen similar vertical line on an EX90 LCD screen, but this is first time I get to see somebody report such a failure on the touch panel.

I think the principle is the same. Screen matrix of rows/columns has a defective column of pixels.

Hardware issue I would say.

Interesting fact here is that this was not an issue when the unit was unboxed out of the factory. It just appeared after some time.

Cheers,

M.

Hello,

I am still inclined to say this is hardware error.

In the case of the bad LCD, when we applied "light" pressure on the top/bottom of the vertical line, the vertical line sometimes went away, but re-appeared afterwards. You could try same on your touch panel.

I have the same issue on two devices, MX200 G1 and EX90,  funny thing is that it disapears on MX200 after a while, I think it might be a firmware or software.
