Hello, the laptop has no image, if I notice flashes on the screen when I illuminate it with a flashlight, the voltages I think are correct, except for one that varies from 0v to 3v constantly, I have measured it with the oscilloscope and it measures a signal quadratic an unstable pulse, I think it may be the brightness, but I'm not sure, lacking the scheme I'm blind, I also want to tell you that I'm learning to repair laptop and I still have a lot left.
If you can help me, I would appreciate it, my interest in laptop repair is not commercial but research and learning. I have downloaded several BIOSes but none of them works for me, only the one she had is the one that works, but I don't know if it is corrupt or no, it's my first repair project.
a greeting
