The P13USB chip on the board is responsible for video output signals to the USB port. It is not uncommon for it to need replacement, or any of the data chokes on data lines coming from the chip could be bad.

If you want to jump down into the rabbit hole, you can find [link|https://logi.wiki/index.php/Game_Console_Diode_Mode_Measurements|diode mode measurements f|new_window=true]or Nintendo Switch, including normal values for all the pins on this IC as well as the charge port. Just scroll all the way to the bottom of the linked page. (Images are not mine otherwise I would stick them right in the post). But you will need a multimeter with a diode mode function, test leads with small enough points to isolate the individual lines and some magnification will help loads.
