    Hello all.

    One of my computer monitors (BenQ E2420HD) recently broke. When I turn it on, it's good for a couple of seconds, and then the picture disappears. From what I've been able to gather from the internet, it looks like the issue is likely that the backlight is turning off because it's drawing more power than it can handle. I opened it up to take a look at the circuit board, but none of the components actually seem to be damaged. I've taken a bunch of pictures, and was hoping that someone might help me to know what I would need to replace.

    Album here.

    Thanks a ton!

    On the second picture far left side there are two transformers that is the back light driver, assuming that you are correct in your diagnosis...
