Nintendo Switch doesn't turn on

"Hello Łukasz Zakrzewski,

Have you tried switching the battery with another one. Or have you check the readings of the battery with a volt tester?

Recommend disconnecting the battery. Then hold down the power button on the switch for 30 seconds. After plug-in the battery and check if the switch charges.

If this doesn't work, you could have a bad battery.

Hope this works for you.

P.S. let me know if it works for"

"Hey,

Try to check the amp when you charge the switch, if it is 0.40 this is normal slow charging. If it is around 1.75 it is fast charging. So if you connect the switch and after a minute it didn't switch from 0.4 to 1.75 there is a problem.

Check any liquid damage, search for corrosion and check the tiny sticker, if it is pink there are liquid damage.

Check if any capacitors is shorted, check the fuse and the chip on the right of the USB charge port when it face you.

In the case on of the capacitor is shorted you will need to replace the ship."

"Hi Nahuel

I had the same problem with my Nintendo Switch. Try this remove the ribbon cable from the game card slot that is connected on the left hand side. Next grab some rubbing alcohol and clean the ribbon cable and the pins with the alcohol. (Careful not to use too much of the alcohol as you might get the LCD screen or other components burnt). Last reconnect the ribbon cable back into the slot and turn on the system. This is what I did to my switch not 100% sure if it will work with all Switch's."

I had the same issue on a friend’s switch (backlight on but no display when powered on) but at the end, the issue was that it was stuck on RCM mode. Injecting a software from my PC solved the issue.
