Solved! Dell inspiron 1525 black screen

[hobbbes58017]

I have a dell inspiron 1525 and the screen goes black after less than 5 minutes of use (displays fine connected to an external monitor) I can still very, very faintly see the cursor but nothing else. I've read in a previous thread that it could be either the screen or the inverter board. {http/www.tomshardware.com/forum/62706-35-dell-inspiron-1525-screen-black} Is there any way to tell which it might be?

It could be the CCFL backlight in the screen or the FL inverter board which powers the CCFL backlight.
