connector disconnected PP5V_CAM diode mode to ground 0.260 connector connected PP5V_CAM diode mode to ground full short circuit removing LP610, connector connected starts normally conclusion ---damaged camera? to get to it I have to disassemble the screen?

Not 100% success yet. if connected, this flex stops at 5v after connecting the charger. If the disconnected macbook boots up normally. I do not have a password to enter the system. I guess I'll format it. what is it for? (camera ? )

I look and do not believe. it went on 19 v how did you know? I put it all together ...

I will give voltage in the evening. you can help with what kind of bios I can trust

PP3V3_S0 1,2v the thermal imaging camera showed the heating up U8030 has been replaced PP3V3_S0 1,2v 3,3V the computer restarts for 13 seconds no sound during startup PRAM reset.... nothing changes attempting to run in SMC bypass (the fans are running at full speed, no startup sound, no...

replacing the battery solved the problem the laptop will go to the daughter instead of the garbage can

PRAM reset did not help You should check if macOS says to replace it. I do not have a password to log into the system Can I restart this laptop and log in the new user without knowing the password to the old one ? two days ago I'm sure the charger gave 1.5A at 19.5V Did I damage something?

after connecting the charger, the meter shows 19.5 V and 0.3A but I do not hear the sound of USB connection. There is a sound when the macbook starts up.

I'm not sure what you mean but when I see the login screen I also see a battery icon that shows 45% of the battery charge

You were right, my next step was to desolder the screen on the matrix tapes, it turned out that there are traces of flooding under the screens and corrosion after cleaning everything, the backlight of the screen has returned but there is a new problem, the battery is not charging :-(

So you mean we've stopped moving ? do you have any more ideas ?

will it be possible to inject the backlight voltage somewhere ?

yes R8447 9.95 kΩ R8450 0.1 Ω R8452 1.542 kΩ R8453 1.543 kΩ R8451 0.1 Ω R8442 0.1 Ω

R8450 0.1 Ω SCL lines 0.536 5.1V SDA lines 0.537 5.1V I do not have a display with a backlight for replacement
