Default BenQ BL2400PT no backlight

Hey!
So starting yesterday - my old 24" LED display doesn't work well - device displays image but there is no backlight and I can hear hissing from power supply.

I've tested lcd 6pin power cable and here are the :

Black standby 0.4v power on 3.7v
Brown standby 0.4 power on 3.4v
Red standby 21.8v power on 28.9v
Red standby 21.8v power on 28.9v
Yelow stand by 0.4v power on 3.7v
Green stand by 0.4v power on 4.8v

Any ideas what's wrong with it?
