Dell Inspiron 1501 laptop LCD screen is dark

[start2style]

Hi everyone, I am having problems with a Dell Inspiron 1501. The screen was doing ok, but it has recently started acting funny. The power button for sleep was pushed on the dell and ever since then the screen is extremely dark but it will display on an external monitor. What could be wrong? Thanks

sounds like the backlight or the transformer that powers the backlight has gone out

It's the small inverter board inside

You need to dismantle the screen (front bezel off, and obviously all power out first)
Then locate the inverter electronic board, part number; search (Google?) for it and replace it, for a working one
