Last night, a user brought a 22-inch Konka LCD TV, model: LC22ES61, the phenomenon of the phenomenon is negative image, ghost face.
Disassemble the machine this morning, start with a simple, re-inserted cable, the fault remains. This machine does not have a separate logic board, the logic board is with the motherboard, observe the motherboard, find the target AS15-G on the motherboard, touch the chip, very hot, well, it should be it. Cutting the chip pins directly with a wallpaper knife is much faster than using a heat gun. The blade must be sharp, master the strength, avoid scratching the copper foil, and clean the pad after removing the chip.
Replace with RM5101, this chip can replace all AS15 with different suffixes.
After welding, start the test, a successful, fault repair.
