Hi I got this board and it has no green light PP3V42 .9v I found a cap C5002 shorted and removed it :/ I didn’t find corrosion around smc. It looks like it’s been tossed around parts are knocked off and u2940 is cracked. I don’t have this size caps or a donor board yet i need to order one is the TPS22920YZPR from digikey compatible ? Also Same question for u1950 from digikey

At L7095 Before removing cap
5 ohm
Diode mode
.06v

after removing

47k Ohms
diode mode .313v

Can I power it on without this cap ? Is it critical?
