Can you take another photo please of the replaced chip? I need to see the quality of the rework solder connections.

To identify a blown chip, search the PCB part number online to find high-resolution photos of an undamaged board for comparison.

Look for identical "twin" components elsewhere on the circuit, as many power phases or audio channels use the same hardware.

Check for shorted capacitors nearby using a multimeter, as a faulty chip is often a symptom of a larger power failure.

to begin with.You have to know what to ask AI. You are contributing misinformation and I believe you are doing it intentionally because you do not know what you’re talking about. I’m just giving you enough rope to hang yourself bye-bye AI…

That “blown chip” is an 1.8MHz fixed frequency, synchronous current mode, boost converter.
