I have a nintendo switch lite here with no display after I repaired it. I have no clue what could have went wrong, but I need help.
I got it with bluescreen. So first i reflowed the CPU, it seemingly worked, but I had no display (backlight, touchscreen, everything else seems to work fine). I took the CPU down, reballed it, just resoldered it, but still no display. Everything else works, I have all the keys (they make a sound), well sound, touch works and backlight. The switch charges as it should.
What can I do? Maybe flux in the connector of the screen, but i flushed it with ipa several times. Under the microscope i see no damaged pins.
I bought and tested with a new display, still just backlight. So it is a problem on the mainboard. Which chips are responsible for picture of lcd on switch lite?
Hi there, I am very sorry to answer so late, as I really did not notice that someone has answered to my question.
I am not 100% sure which pins you mean, but I will add a picture with all the voltages I measured on the shown pins.
I still have that Switch Lite and it propably still has this issue. However, I got some magic smoke for whatever reason while trying to connect the daughter board, so I need to change its connector on the mainboard, the flex cable and I bought the lcd driver, which I still want to change aswell. If nothing helps, I can safely assume that my APU reball was faulty, so I would indeed redo the apu reballing and stuff.
