One of the fans was bad replaced everything was fine started to get a flickering green on the left corner of the LCD. Customer got frustrated replaced the board entirely i think this could have been bad soldering the the lvds connector my brain was fried on this.

ASD Checked out fine. I ran the fan test and it gave me an error says motors failed to spin up properly or something

.616 .614 .598 .613 .613 .601 These are the diode mode readings.. "Diode mode all the LED return lines on the connector." Its fixed now the LCD is working well after a Brand new connector install but the fans are spinning up now loud it wasnt doing that before and its taking forever to load...

LCD connector was greenish had pin 39 and 40 looked really bad replaced connector replaced cable replaced LCD. I'm not getting voltage on those pins either. Still no back light.

Done. We get a fan spin. now. Pads were ripped under the u5110 is there a technique that can be used here to replace these pads when you have chips with no legs. I used a wire from cleaning wick and it worked but is there something more solid that can be done. ? cause the chip was kind of uneven.
