    Hello. I have an LG 27GK750F-B Monitor that I've been using for roughly two years. Randomly the other day the display turned permanently white. I have diagnosed that it is not any of the external cables nor PCs associated with the monitor. The monitor also shows a slight buzzing sound coming from the back (I'm not sure if it was there prior but I do not believe it was). I have disassembled the monitor and verified that none of the internal cables were disconnected. I was wondering if anyone had any idea what specific parts I would need to replace to potentially fix this, or possibly any other solutions which would not require me to do so. Thanks in advance!

    Here are a few follow up pictures of the monitor (front, back, inside back):

    Also, here is a link to the spare parts website (https://partstore.encompass.com/model/ZE...). If anyone has any guidance on the website as to which parts I should get if needed, I'd greatly appreciate it, instead of having a repair shop up-sell me for a fix I could do myself.

    It could be the power supply in the monitor.
    Open it further and take clear photos of the pcb.

    Thank you for the reply. Hopefully this picture is sufficient.

    The image above isn't appearing for me, but here is the direct link to the image since I did not want to upload a compressed variant that is hard to see: https://imgur.com/5tFoGhC
