Hi Deck,

When I encounter this, I usually assume the part is defective and see if the problem persists on another screen. In testing I have figured it is the driver IC on the screen assembly, replacing it with a known working one fixed the issue. Unfortunately this is a advanced repair, and you would need a donor screen (maybe your old one?)

Good luck!

Thanks for your reply.

Yeah I think it is the driver IC, the one that on the flex cable. Maybe the technician told me it was my audio codec since he doesn't want to replace the LCD that I bought from him :(
