LG IPS236V question

[tibimakai]

Got this monitor with box and all the accessories, all packed up in nylons for $20(!!). Some of the nylon wasn't even removed from the stand.
Found out quickly that the power adapter was oscillating, so I had one laying around, but with the wrong plug, so I have just switched them and the monitor started right up.
But I have noticed this on the screen and I don't know what could be the problem.

If you mean the lighter marks could be a pressure mark? is it there when you have a source connected.

Those blue spots.
It shows with signal also.
What's happening to the screen when there is a pressure spot? It can be repaired?
