Keith Wakeham, an engineering student replaced the backlight of a LCD monitor to operate using LED lighting.

“My very wonderful cousin gave me an old 17″ LCD made by the company GEM (I don’t know who they are) which was making a big racket with squealing. I knew it was the backlight so I said I’d take it knowing that to get it repaired by a pro would cost 30-60 for the inverter and a few hours of labour. Being A poor student that wasn’t going to happen but I knew it was a decent panel and wanted a second monitor for my laptop.

So I decided to see if I could drive the existing CCFL’s with a Computer UV CCFL kit and barring that would try LED’s (Which are salvaged from Princess Auto Head Lamps).”
