2. when I plug the machine in (power - kinda spectrum like... due to
lack of a switch) it sometimes shows vertical black and white strips
across the whole screen. They may go off by themselves or I need to
re-plug the computer before they disappear. Is this something "normal"
or should I look for more damages on the board?

The strips should go away after self test.

If they don't you will probably find it starts up better if you apply AC
power to the power adapter before you connect it to the computer.

You could try changing C21 from 1μF to a higher (maybe 47μF) value as a possible way to make it start up more reliably.

But basically the problem with it, as it is, is that it needs the
internal 5V to go very quickly from 0V to 5V at power on or it doesn't
start up reliably.
