Guide needed on how to replace inverter board on my Inspiron 6400 Laptop

Hello,

Some time ago I released my laptop from Standby whereupon I was faced with a blank screen but the display can be seen in bright sunlight or by using a flashlight.

I purchased an external VGA monitor but have subsequently realised that I cannot boot using a EaseUS Emergency Disk without first being able to get into my BIOS to change the boot sequence and to be able to do this I need a working laptop display.

My plan was to create an image of my system using EaseUS Backup but unless I can fix my laptop's display then if my hard drive crashes I have no means to restore my OS ( Windows XP ).

I don't have the finances to buy a new laptop so choosing the cheapest ( and easiest ) solution where hopefully I find that replacing the inverter fixes the problem.

What I need is a guide in how to take out and replace the inverter with my particular laptop model.

Once I know my inverter's part number then hopefully I will find it online where I think lcdparts.net might be my best chance of achieving my goal.

Can anyone please be of assistance?

Thank you.
