not backlight, I tried screen good problem persists, fuse bad not short in the fuse, some more measures before just changing the fuse? I'm scared just change the fuse and damage the good screen or is that not possible?

Post diode mode to ground on both pins of D9701; w/ and w/o LCD connected.

 

[andrespi]

PIN 2 D9701= 0.62 PIN 1 D9701=0.44. w/o
pin 2 D9701= 0.62. PIN 2 D9701=0.44 w

If there is a lcd or motherboard problem, how much would it give in diode mode?

Not bad values, you can try changing the fuse.
If burn again, change U7701; can you see any corrosion between its balls now?

 

[andrespi]

I already changed the fuse, and it did not burn.not see any corrosion between its balls,change U9701?

[andrespi]
