Hi

Same model and same issue here.
My question is have anyone had any success replacing IT8226-192 one with IT8226-128 version and get it to work on Y540 model ?

UPDATE :

Flashed 192 verison with 128 firmware, it worked and posted without display, but HDMI outputs picture. MB have LCD power circuit issues and I m working on it

I can get picture only on HDMI output, keyboard is not functioning at all, and mb shuts down as soon as it boot to Windows.
Gonna order 192 version and try with it.
