But this is where a repair depot has it all over us. They can swap in another to be sure. The internal display doesn't use the same circuits as the external so while it's an OK test it really doesn't tell us much.
Hello i have a lenovo b570 laptop. I recently replaced my laptop screen and also bought new display cable. But screen colours are bluish, i mean there is no proper white colour only bluish. I also checked my laptop by connecting it to external monitor and everything works fine. So i showed my laptop to computer expert and he is saying that this problem is because of motherboard circuit short. So i just want to ask that can some short circuit of motherboard cause colour of laptop screen?
