Nintendo Questions Nintendo Switch

Need a bit of help. I have seen this question asked online, but no answers were given.

Nintendo switch turned on with a known working battery, but will not charge.

I replaced the USB C and it now receives a charge. However it will not turn on

If the Backlight is plugged in, but the LCD isnt then it will turn on the backlight. Please help if possible.

Is the lcd screen working on an other Switch?
Is the lcd connector ok and has no bent pins?
Did you get a picture on a tv if the switch is docked?
What current is drawn if the original Nintendo power supply is plugged?
