LCD temperature boot problem

본문:

From one day to another computer monitor has stopped working properly. CHIME is heard but not seen the white snapshot start. Also does not connect the keyboard (even USB) so I can not start the session.

Can the graphics card cause such a problem (not able to connect to mouse and keyboard)? Does the display cause this?

I dont want to buy another display and find out that It wasnt the problem.

Is there any way to start a session without keyboard or mouse. I need to check if I can use a external screen, to see if the computer still work properly beside the disply matter.

Any ideas???

Do I have to change the whole LCD or I can resolve this matter in temperature? I think it may be a problem with the temperature sensor, but in this version of Imac, the screen does not have the temperature sensor cable, so I miss a mess.
