Blank screen on Dell Inspiron 1545
Posted on 2011-03-05
I have been brought in a Dell inspiron 1545 laptop for a screen replacement, the old screen was cracked but still working. ever since I installed the new LED screen I have not managed to get anything on the screen at all when I boot-up the machine. I thought I might have damaged the cable that connects the screen to the mainboard so I have replaced this cables twice with a new one but still no joy, I have also installed two new screens but still nothing, I installed the cracked screen which was working before I removed it, this is also showing no signs of Life.
I have booted-up the machine with an external monitor connected and it boots up no problem at all, I have also pressed the FN key along with F1 key which toggles between the external monitor and the laptop screen - external monitor works fine but still nothing on the laptop screen.
any help in resolving this will be greatly appreciated
