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.

The first pic is blurry, hard to tell the health of that fuse.

 

Personally I wouldn't try soldering on a motherboard, but then again I'm not trained on it.

 

If the laptop is dead after you soldered the fuse onto the motherboard, I'd say you didn't do a good job. Sorry.
