Ah, so now they want me to void my warranty. Here's the response I just received: Seller's message: "Dear.******** okay. Please let us know the serial number of the monitor. We will send the pcb for the fix it. Thank you! Alice " I suppose it's better than nothing, but it sounds like they are going to send me an internal part that I'll then have to swap myself and void the warranty in the process. They could also be referring to a new power brick, but it does say "pcb" in the message. In my response, in which I'll give them the serial number(shouldn't they already have it?), I'm going to bring up that point. It would be completely unfair if they sent me an internal part to replace and then not take the monitor back(if this doesn't fix the issue) because I opened it.
