Dell SE2416H -need help identifying a component

[Djosla]

I have a 10 days old Dell SE2416H with failed video board...Main processor had a dead short and it was replaced but i have i diode D110 blown which i can not identify...It is labeled as D110 but it has transistor markings B,C,E under the component...Component itself is blown but it is sot123 housing with marking WW* (* is the demaged place so i don`t know full marking ) Please take a look at photos...Any help would be appreciated...

What is the P/N as printed on top of U703 (56953???) which has one of its leg connected directly to the 'E' pin of D110? That may give a clue as to what D110 is.

Exactly but those smd markings are very hard to read correctly...I took a risk and turned on monitor without diode...It worked ok but hdmi input was not detected...So i took measurments and i have concluded that missing diode was powering a U110 eeprom from U703 and 5v from hdmi connector (pins labeled B and E of D110,pin C goes straigt to 8 pin vcc of U110)...So i put BAT54C diode in place...I had to replace the U110 eeprom because it was also fried. 24c02 replaced with 24c04 and freshly programmed and voila...Works as it should...

Dumps for future use are in attachment. PN number of this board is slighly different from the one in dump but worked...


Thanks...
