Hello,
I have tried myself but I have problem looking in chineese for parts at least what is laser marked here doesn't help me to even find someone from china selling that IC. I have managed to find SOT23-6 power IC which also is burned. For my guess it's probably DC-DC converter of some kind when plugged with known good LCD what comes extremely hot first is SOT23-6 power chip which I have managed to find at Ali and order like 50 of them. For some suggestion this board works from type C PD power supply 20V input.
I could buy another board, they are not particularily expensive but if I could fix it and just stockpile components which go bad when plugging faulty LCD that would be nice. I have bought those boards for testing LCDs before mounting because I had very unpleasant experience with client where LCD panel directly from supplier killed MB completely so it's cheaper to destroy coversion board rather than client's device.
I am looking for V1CNA chip or VICNA but I couldn't find anything.
