Blemish, Spots, perhaps Dust in left lower Corner...
After using my LED Display for about one year, those dark spots appeared in the left lower corner.
I tried to clean it and removed the front glass panel, because i thought they were on the backside of the panel.
They were not.
This dust-blemish or whatever it is, appears to be at the INSIDE of the LCD part. Anyway, I think before I am going any further with my cleaning tasks, i should ask, if someone had a similar problem and maybe have some ideas to solve it?
A picture of my display is there:
I'm grateful for any help! thanks in advance!
