Hardware Monitor Advice Please :)

My friend gave me a nice 19 inch LCD monitor but It needs a new back light. This is the monitor

Optiquest Q191WB-3 by viewsonic
Part # VS12105

I already contacted Viewsonic and the part and monitor is no longer in production. Does anybody have any idea of which website I could go to to find another backlight?

Not sure where you will be able to find the specific part, but I buy my tubes from ccflwarehouse.com as well as eBay. I believe ccflwarehouse has instructions to measure the tubes. Tubes are thin, fragile and contains mercury, handle with care.

Bad inverter boards and such also causes a non working backlight..

I will echo dilav's check the boards- monitors seem to be one of the main things I replace bad capacitors on (primarily as if a non program/tool specific part drops dead after 4 years most call it a good lifetime and replace it but monitors seem to want to last a decade) by the looks of things that was made slap bang in the middle of the period where bad caps were used. As mentioned it is not always caps though with dead inverters and bulbs (sometimes as the result of a dodgy inverter) doing damage as well.

Equally I have seen a few people retrofit old CCFL boards with some of the shiny new bright LEDs coming out. Other than making a poor man's projector I have not really done anything here though so I can not comment much more than that. Naturally you would be laughed out of the parties professional monitor users go to but getting a new shiny monitor for next to nothing makes up for any loss there.
