GREEN LINE β GONE. π¬β‘ No display replacement.
This Samsung Galaxy S21 Ultra developed a green line after a software update.
Instead of replacing the entire OLED display, I went directly into the display circuitry using an ITO laser machine.
π¬ Magnified and traced the damaged circuit
β‘ Located the burnt display trace
π₯ Precisely exposed the damaged line with the ITO laser
π§ͺ Used conductive paste to bridge the circuit and restore the voltage path
ⳠAs the paste cured, the green line slowly faded away⦠until it completely disappeared.
This is specialized display-level microsurgery that requires ITO laser equipment, circuit tracing and precision repair.
