Hello everyone,

I have thunderbolt display that is acting strange.

1st, when plugged in, sometime it works little bit, and it makes the screen freezes.
2nd, computer shuts off randomly.
3rd, gives out error message in different languages.

4th, turns on, but screen is freezed and can't do anything.

note: this does to any mac computers that connected to this thunderbolt.

do anyone have this issues?
