Good Evening. I have a switch V1 that is charging at .46 but no LCD. When I first got the switch it was charging at 0.9. After the m92 replacement it started charging at the 0.46. I replaced the Max17050 and no change. I’ve been poking around the board and found that I must have knocked this capacitor off. Could anyone identify it for me? Do you think this missing cap could be causing my issue?
I have also measured the following voltages which do not match the guide on this website:
Sorry, my photo will not upload.
The 4 volt line always reads 3.6V and the 5 volt point reads 0. A couple 1.8V points are reading either 0 or 0.6V. This is with the battery plugged and and the switch being powered through USB.
Also, The three components circled in yellow are each shorting (again, no photo upload. It is the three large components in a line directly to the left of the max 77620 IC). I have check what I believe to be all of the other low hanging fruit (bq, p13, ect…) for shorts and have not found any.
My instinct is telling me the Max 77620 is bad and is preventing me from getting to boot. I don’t really want to remove it and then test for shorts just yet as this is a BGA chip and I don’t have a replacement. (I am also not confident in my experience yet).
Auto RMC is off and I can boot into TegraGUI. In Heketate the LCD and backlight work fine and I am not seeing any errors on the battery level (plus is says it is fast charging but I don’t believe it because my meter still says 5V 0.46 amp)
Thanks for any advice!
