Led tv blocked

[rockyrambo]

Hello,
I have a LED tv Inno hit IH 16914T17B. It is 2 years old and it is blocked. The white led in the front of it keeps flashing and I can't turn it on. Anyone who does know how to unblock it?
In the instruction manual nothing about it is mentioned.
I suspect that there is a sort of timer inside it because it stopped working just after the warranty period was over!
Thanks in advance
