must have received some hard bumps during transit because it's
not working properly now. The model is BenQ G2420HD.


Nope. Shock would kill it completely, usually by breaking either the
LCD or the CCFL backlighting tubes. More like it wasn't working
before it was shipped and you were sold a monitor with a known
problem. It happens all the time on eBay. Send the seller a nasty
message demanding your money back, unless you want to fix it yourself.

Follow Arfa Daily's troubleshooting advice with the flashlight. If
you can see a faint image, then tear the monitor apart and look at the
power supply inverter PCB. Look for bulging caps, exploded parts, and
a burned PCB. All are common and repairable. What's not easily
repairable is a shorter LCD backlighting transformer.

You can buy a rebuild kit or a replacement board:

I could not find a capacitor and semiconductor replacement kit for the
BenQ G2420HD. Sorry.
