there's a dent in the corner, deep enough to expose the bare metal, and it does this:

I've seen multiple people with, what looks like scorched VRM's on a daughter-board inside of these monitors. I just ordered one of these from lightn.space a week ago, so I should hopefully be seeing it here anywhere from Friday to early next Monday. If I were to open up the monitor and put a small VRM heatsink for a GPU or a motherboard would this make me less likely to have the same problem?
Thanks for any replies. wink.gif

I had the same idea and i think im going to open up the monitor tomorrow and see if it looks already burnt or anything. In any case im going to try to mod a somekind of heatsink for the component. Can't recall which thread it was, but i saw photos of a same issue from other users so i try to play safe and prolong my monitors life as much as possible biggrin.gif

EDIT: I opened up my monitor and i found the board. It is not the same board that Mikelanding has. It is green and has different components. Nothing looked burnt and nor felt hot to touch. I guess this is a new revision or something? It has a date 2012.05.12. I guess they have adressed the problem on newer crossovers. I've had mine less than a month.

In case anyone's curious, I gave up trying to find a cheap video card that could run two of these at the same time after I had to return two of them. EVGA support is clueless about which of their cards have two dual link ports and it's never listed in the specs. Other vendors might have better support.

Oh well. My old 8800GTS works, but it gets hotter than the sun frown.gif

Well, at least I am probably not out $400. I am not sure what will happen with the amount I paid in duty and taxes, though. Can you be reimbursed for that if the item is returned?

There is no reason to buy a pixel perfect with their policies. I got each of my led-p for $360 each. That's why I said I hope the crossovers comeback down in price for everyone.

So red-cap has shipped my replacement PCB, and in anticipation of its arrival (still not for a few days) I decided to crack open the monitor and see what I could find.

Taking off the back metal case was easy, it separated into 3 parts. The largest part had the primary PCB attached to it, which was connected to the LCD panel itself. There was a smaller PCB on the right, which I presumed to be the LED controller (same wiring that went to the LED adjustment buttons and two black outgoing cables to either side of the panel). It was readily apparent what the result of my problem was when looking at the LED controller, and I've attached some pictures so that anyone in my situation in the future can potentially chase down the cause too. Here is the LED PCB, and the discoloration and burned up area should be a good indicator as to what went wrong:

Its a MOSFET on the LED Driver board. Mine failed too. Just emailed AccessoriesWhole to see if he has any replacement boards.

I bought from red-cap and he's already shipped my replacement board (though he never specified which board he sent so now I'm paranoid he sent the wrong one) but hopefully its all good.
