Nintendo switch black screen no shorts : switch took a bath

This for someone who is experience similar issues:

Switch Powers up. Normal charge and readings. Nothing on screen.

Tools hours of measuring diode reading and cannot figured what Wrong.

I started connecting one thing at a time and power unit unit every time I connected something. Boots normal and video on screen

Finally found out I have a 1 bad or shorted speaker. And 1 bad joy con rail connector.

Each problem causes it to have a black screen. Connect everything else and system running normal.

This just for people experiencing normal charge no shorts with black screen.

Hope this helps someone

Thanks for the info

Out of interest, when you had this issue were you seeing the nintendo logo at boot or was it always a black screen?

Black screen only with backlight one. Charges normal at 0.4 then drop to 0 then jump to fast charge

ok, thanks for confirming
