Thanks for the quick reply. Measured winding on both transformers and am getting resistances of 905 and 915 ohm. I would think they are ok?
Connected another capacitor of the same value in parallel with the KSC (essentially making sure that I get the capcitance required) and it made no difference. Perhaps this cap needs to be replaced...
Checked the screen with a flashlight and I can see the computer icons (very dim) so definitely this is a 2 seconds to black issue type. It seems like the CCFL...

I need some help with my PC LCD Hyvision by Megavision MV220 monitor.
