Hey all, I have an issue with a Switch lite. After installing a picofly, I powered on to test and saw a puff of magic smoke but I’m not sure from where it originated. I immediately powered down the system to check for damage and didn’t see any burned components, but I noticed the lcd driver (8316 chip) was cracked in the corner. The system still powers on and I have backlight but no display. I replaced the 8316 chip but no dice, so I started checking voltages and one of the test points near the lcd driver measures 1.8v (normal), but the other measures 0v and this is the one that comes from the SOC. So the lcd isn’t even being told to turn on 
I think these voltages stem from the MAX77620h chip on the back of the board, but not sure. Where would be a good place to begin to troubleshoot this? Or am I completely screwed here?
The system powers on and the backlight, sound, and touch all work fine. I just can’t see anything lol. I have uninstalled the modchip to rule out the possibility of improper or bridged solder joints. I’ve also double checked the screen fpc connector and ribbon cables to see if there were bent pins, but all is well. Thanks in advance for any guidance.
