2 Monitors same symptoms - BenQ

[scoreed]

I have two LCD monitors, a BenQ Q7T3-FP737s-D and a BenQ Q7T4-FP72G. Both of these monitors were manufactured in August 2005. Both have broken back lights, however I can not find out where the problem is, i'm not sure whether it is the CCFL tubes or the caps? The the display works but neither of the back lights in either monitor turn on. If you need any pics I will post them ASAP.

Thanks

Post pictures. If you can't tell by looking at them, how are we supposed to tell WITHOUT looking at anything? In general, if the backlight never comes on the problem lies with the inverter (or power supply).

A case mod light kit will make testing much easier. Use the CCFLs supplied with the kit to test the monitor's inverter. Use the kit inverter to test the monitors CCFLs.

I agree. No image, no ideas
Try the case light kit idea : it works wonders for me.
