[nelo1012]

have this 820-3435 that came in with liquid damage, damage close and around SMC, Replaced SMC and damaged parts around,

Everything worked fine until I booted it up, it has a flickering/ distortion on image, and there is no sound,

It's going into sleep mode so SMC_LID is being pulled low. Probably corrosion on trackpad/connector/flat cable. Could be crap on/under the Hall sensor J6955 too.
All audio is on the IO board, so probably bad IO board and/or flat cable.
