My acer aspire 4710 had some CCFL issues and i opened the display bezel and push tight the socket, it was working fine, then , again to make it tight, i pushed with screwdriver, but accidentally the screwdriver tip shorted the outer of the socket(metal), and one side of fuse, i saw an small flash, and then on the display is working, but No CCFL.
1) I checked the CCFL with other laptop inverter out, it was good,
2) i checked the continuity of display cable to inverter, it was good
3) so I felt there is one small SMD marked F1 near the dispay cable, which had opened, tested with multimeter, but i am not sure it is fuse, but since it is maked as F1 i assumed so, then i closed it using small copper hair.
After this i tried to check, but the laptop is dead, even if i insert the power jack, there is no sign of notification light of charging,
i checked the output of power adapter and its good, it gets into the board of 20v.
But I have heard , there is fuse neear the power socket, but i did not find any with named FUSE or F1 or so, but there is marked D28 in board and the component is marked as CH7e A14-A, what is this component, please help me solve this problem.
