After a few hours it randomly powers up and this happened out of nowhere, it had no problems before that and it wasn't progressive problem.

I'm assuming you made sure the signal cables are OK.
Your GPU may be dying. Run this: http://www.ozone3d.net/benchmarks/fur/
and if it kills your signal I'm right.
If it passes the test just fine consider cheching your power saving features, there could be some component going to sleep and not waking up properly.

Its not the GPU. When connected to nothing or the ps3 it does the same things, just a blank screen with a blue blinking power button, its not even orange to indicate that there is nothing connected to him

Probably one of the lights or some other internal component is broken. Repair it or replace it.

How much would it be worth?
