Hi,
I have a DL4 totally dead.
the board has p/n 35-00-0404 Rev A of 26 Oct 2012.
The power section is completely dead,
and I can't identify the 2 ic's, U23 and U24.
The ic U23 I think is an RT7237, identical to the MAX887,
the U24 I don't know what it is, it has a DL=3J526 identification.
someone can help me? Does anyone have the wiring diagram for this card?
