You switch on the PC and it boots all the way to the desktop, but the problem is that there is no screen display during the whole process.
How do you know that it boots all the way when you cannot see anything on the screen?
To check if the video card on the laptop is functioning properly, connect the laptop to an external monitor. When you boot up you may see Windows start on the monitor, if not press the Fn key plus one of the Function keys that switches (toggles) between the LCD and the external video (usually one of the keys from F3 to F8).
If you don't get a video image then the video card which is part of the motherboard, is faulty - it can't be repaired cheaply, usually requires a new motherboard.
If you get a video image on the monitor, then the LCD could be faulty or the LCD video and/or backlight connectors on the motherboard is not making proper electrical connection. Then it may be fixed by reseating them.
Found Wiring to LCD was damaged in Right Hand Hinge - Red wire was broken ( supply for back lighting ) resoldered made safe all good. Scotty
