Re: packar bell le69kb no image

Well after doing all the measurements and reprogramming the bios, everything was the same, remove the RAM memory card and change it, and it was still the same, check by putting 2 cards of 4gb each and BOMMMM was started, that is, to me mellego with only 1 4GB RAM card and I believed that everything was correct and yet nooo has to use both cards and case closed.
Works correctly.:maricón:

Re: packar bell le69kb no image

Today I checked the board again and found that the LCDVDD_EN_APU signal coming from the processor is not stable, and therefore the EN (pin 3 of the U3701) is not stable, so
the voltage of + LCD_VDD_EDP does not stabilize and I think it is the BRIGHTNESS of the screen, I suspect
that the U0701C processor is not right, I think I'm going to rebaling it, I'll tell you what the result is

packar bell le69kb no image

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...

Re: Packard Bell EG70 bios dunp needed

Hello, I don't know if the bios I have can help you, one is from my own laptop and the other is downloaded from wed pages.
I hope to do it well, I explain what happens in mine is that it does not give an image, what I do notice is that if I put a flashlight on the screen, flashes are perceived, I cannot investigate further why I am missing the diagram, if someone has it , if I can publish it.
