I have a Switch OLED here. This has the error that power out directly after the Nintendo logo.
When I connect it to power, it charges with 15V and 0.45A.
What would you look at first?
So it remains permanently at 0.44A-0.48A. When does the switch go into fast charging and how much Ampere does it have then ?
Nintendo logo only comes when I disconnect the Switch from the charging cable and then goes out.
I hope it’s not the NAND.
What could I test first?
So. This Caps Are shortet. They have on Both Sides Signal to ground.
Battery has without power supply 3.7-3.8V and with Supply 4.08V and loads still with 0.45A on 15V
