I cannot recognize it either. Are the numbers and letters printed blurry or was the camera moving or unable to focus? If you can just transcribe the numbers/letters in each row of the chip, that would be easier to read.here is photo but cant recognize it

thank you very muchIt is rare that an IC burns on its own. Typically a downstream component fails (short) and too much current is drawn from the IC so it overhears and cracks or chars as the silicon or tiny wires inside turn red-hot. If you replace it, it will likely burn as well unless you find a shorted resistor, diode/LED, capacitor or inductor that caused the problem. It is possible that the chip just overheated on its own because of bad design and just a little too much current its whole life and changing the damaged chip may work. But, SMD chips are touch to identify so you may be better off trying to find a power supply board from the various eBay sellers who recover and test boards from scrapped TVs.
Jimmy has been doing this for a long time and he knows this board is used in hundreds of Samsung models.
