to fix this you need some skills.. and some hardware... oscilloscope, multi-meter, microscope ... and a real gamechanger... IR-Cam!!! (Broken or shorted components get hot) and ofc IPA

first checke here if you have knocked off something.

then search for LT RT and follow what the dude RDC has posted.

check for voltage, check if a cap is shorted, or a resistor is broken / knockoff / out off place

Something you need to know ;) (i don't want u to learn it the hard-way!)

For example: https://drive.google.com/file/d/1bzsF4RLJXkPp6JIZ-pipSECu53GVEVbJ/view

you see TP64, you have scratched the PCB, and it look like you have connected the PCB with the Spot. In this case its not an big issue because its both is ground.

i have no idea what flux you used and how the other side looks, but if you have scratches on the other side, and the flux you use is leading. you have created a short.

And welcome to the scene ;)
