Issue: Have a problem with a laptop when screen went blank.

Quick check: If you shine a strong torch at the screen is there an image?

Possible problem: Backlight inverter

Apparently a common problem is a faulty backlight inverter. One quick test is to shine a torch onto the screen to see if the image is actually still there. On ours we used a Big dolphin torch and the image was still there. So have sourced a backlight inverter from trademe ( bwl http://www.trademe.co.nz/Members/Listings.aspx?member=512606 ) will update blog to show progress.

For Compaq there is a fix-it video “Replacing the laptop backlight inverter” on http://www.youtube.com/watch?v=ucaJA324hbg

Well that didnt work so back to Dr Google

Possible problem: CCFL lamp

Possible problem is the CCFL lamp. This is much trickier to repair… we may give this a go to.. who knows and we’ll learn heaps as well.
