I am facing some problems with my Lenovo Thinkpad T410. The screen acted as seen in the attached photo. I disassembled the laptop following the service manual, took out the LCD screen out of the cover, connected the screen again and it was acting the same, but system etc. started normally. I ordered a new screen on eBay and put aside the disassembled laptop waiting for the part to arrive. When it arrived, I connected the old screen just to check if the computer itself is still fine and there's where problems have begun. When I start the laptop, the cooling fan runs for a few seconds, then stops for 10s and starts to run again at high rpm. The screen doesn't work. The same is for the new screen. External screen connected via VGA doesn't find the signal.
What's wrong, what to do?
