There is a laptop - Dell Inspiron 1545.

A problem is a brightness of a screen is 0% (when BIOS starts, Windows works - all time). I can barely see a picture on a screen at a big angle (it seems like the screen doesn't work totally). The screen doesn't have the power.

BIOS doesn't report any errors.

You can see that 0% brightness effect if you have a turn off screen button on your laptop. Try to turn of and you must see a picture on a screen anyway but at a very big angle.

How can I fix this issue?


In my (admittedly somewhat limited) experience, this is generally caused by a non-working inverter which will need to be replaced.

  • I would venture to say this is probably the case. Definitely the first thing to check/try replacing. – studiohack Jan 21 '12 at 16:28
