I have a Dell Inspiron E1505 and it started making a buzzing noise. The next day when I turned it on the screen had a red tint to it and then a few moments later it went black. I have it hooked up to a monitor and it works fine. I can kinda see through the black screen, like looking through a black curtain. I am trying to price out the part that I need. Where can I find information about getting the specific part for my computer? Thanks!
