PLS HELP

I’m honestly losing my mind with my Anycubic Photon Mono 4 and I don’t know what else to try

I bought this printer back in November 2025 and after less than 2 months it started acting weird during exposure tests first only half of the screen was working and then after a few days the entire screen stopped displaying anything and just stayed uniformly purple

At that point I thought okay it’s probably just the LCD so I bought a brand new original replacement screen AND WAITED 2 AND AN HALF MONTH FOR SHIPPING then I installed it but nothing changed same exact issue purple light no image at all

Then I contacted Anycubic support explained everything in detail and after some back and forth they sent me another LCD replacement so I was like alright this has to fix it right but nope I installed the second screen and it’s still exactly the same problem

So now I’ve gone through two different LCD screens (both original) and the printer still just lights up purple without showing anything during exposure test

I’ve checked cables connections everything seems fine and at this point I’m starting to think it’s the mainboard or something related to the LCD driver but I’m not 100% sure

It’s been months of trying to fix this and I’m honestly stuck and pretty frustrated because I feel like I’ve tried everything I could

Has anyone experienced something like this with this printer or similar ones could it actually be the mainboard or am I missing something obvious

Any help or advice would be really appreciated
