Sorry can’t release it😅. Notice that pp5v rails are missing, no short.

Find that CHGR_RST_IN_R 0V , no short.

And it can be the reason for 20v?

Don’t find one, but if I get 3.3v on this rail, so the rail is fine no? Do C7690 is important?

But 3V3_G3H_RTC rail not so big, what I need to search for?

I was take UL000 out the S2 line now 0.300 and PP3V3_S2 3.3v there is Chime sound but DP800 0V with screen connected of course. PPVOUT_LCDBKLT_SW 0V -800 on DP800 PPVOUT_LCDBKLT 0V 1080 on DP800

it came from UL000

i was put 1v with high AMP and after a 1sec the short was disappear and i was get 3.3v on 3V3_G3H_RTC, i didnt see and bad cap on 3V3_G3H_RTC rail and C7690 was missing so i thought maybe he was blow out. weird but all 3V3_G3H_RTC rail look o.k.
