this macbook does not give video, it does not have usb data, it turns on and turns the fan, it does not give a green light.

some story: entry with humidity computer turned on with video but backlight worked sometimes. It had some resistors R5177, R5178, R5179 corroded, I changed them and it did not give video again, check resistors and they are well placed, I do not know when placing resistors affect the smc that are nearby. Any suggestions

You should reball SMC anyway.
Check for more corroded components also.

For the Magsafe light issue, inspect J9500 pins and solders.
Try known good LIO board/flex.
