I replaced bq chip with a replacement from mouser as there were shorts when battery was plugged in. Im going to reflow it again but this is the weirdest switch yet. When plugged in it turns on bluescreen, 0.0amps with good battery which has a known charge of 42% or so. when a bad battery is plugged in obviously the switch doesn’t turn on blue screen but it charges a battery at 0.05-0.08amps. There are no shorts underneath the gpu as far as i’ve checked, one of the ram chips had an issue9I was able to boot into rcm and it showed white lines on screen when using biskeys) However hekate is just a black screen and atmosphere fails but the payload does go to the switch. so it appears it will show text and some colours on screen.
Could this still be a charging chip issue like mt or bq causing the gpu to not be able to boot and causing blue screen. because if the gpu was dead I would assume nothing would ever show on screen and their would be shorts o the back of the board.
Anyone have similiar issues? what was the fix?
