Hello, First, my screen was black with a flashlight showing the computer was on. I determined the back light fuse was blown. When I tried to desolder it, I shorted to nearby component. The motherboard was not unplugged from battery. Now, absolutely nothing happens when I press the power button. Can anyone you please point me to where the problem is likely to be now? Thanks
Uh, Charles…there’s usually a reason fuses blow. Their purpose is to save power supplies and upstream components. Therefore, there was probably a short circuit downstream from the fuse to begin with. Failing to remove power from the unit before applying a soldering tool was a major malfunction! At this point, the problem could be a blown component / circuit trace anywhere in the system! Good luck…
