If a resistor is connected to the ground from the positive voltage rail, the voltage will drop. Such voltage dividing resistors are quite common. If we remove this array of resistors one by one, to suit the voltage requirement, voltage will go up. These resistors are provided in the circuit by the manufacturer only for such purposes. Current also can be limited in such a way, readjusting the resistors provided in the source of the mosfet.

Very tedious Job is panel troubleshooting unlike old CRT TVs most of CRT tubes are identical for replacement.

Hello, could you please explain why voltage decreased after removing resistors, should it not be the other way round? Thank you

LG panel will not show LG logo, as the mother board, its software etc. are unchanged. Only the panel and its T-Con board is connected to the mother board. Unlike Sony or other such complicated sets, there won't be any mismatch when we replace the panel.

COF is a short form for Chip on Film. The COFs are bonded to Panel, which is made of glass by a special method. The VGH/VGL and other data lines are fed to panel through this connector. It has an IC on the film which serves as a buffer.
