820-00928 PP3V3_S0_LEFT short

[Djsp]

I have this card going on 20v but with 0.001A I discovered a short on pp3v3_s0_left lifting u8295, mo I can't find the component in short how many Volts should I use to find it ?

What is the exact ohm value of that short?
Did you remove U8295?

There are many chips connected.
Any history available?

I removed the chip because it overheated a lot and then I noticed the short on the feet corresponding to pp3v3_s0_left and it's 0.002 the value to the ground

Then may have luck with volyage injection.
Start with 2V, no more than 3.5-4V...

I took a look at the schematic, pp3v3_s0_left becomes
PP3V3_TBT_X_S0 on r5640 so u2800 is most likely gone. could you advise me on a way to not tear the pads when I go to clean the pond under u2800 thanks in advance

You should search videos on Internet and practice on scrap boards...
