Dell monitor

[dtvmcdonald]

One of my Dell monitors dies. Its essentially identical to the U2312HM I write this on. The symptom is that it works for about 2 seconds after turning on and then goes black.

This of course implies, first guess, a sick power supply going into protect mode.

But how do I get it open? The monitor easily comes apart from the stand, exposing four screws that attach the BPC to a large aluminum structure.
Removing those and the front and back of the BPC are still stuck together.
It must be some sort of "knifing" ... but where and how?

Of course there is no service info.
