Chosen Solution

Hello, I have this monitor HP Z27q 27-inch IPS 5K Display  https://support.hp.com/ca-en/document/c0… which purchased in faulty condition for $15, and I am hoping I will be able to repair it. The monitor has a pink glowing hue from the bottom left corner that occurs 3 to 5 seconds after powering on. I have attached two pics to show the screen is functioning normally when powering on. The previous owner also mentioned that sometimes the screen will flicker on and off but I have not been able to recreate that since I bought it. I am reasonably comfortable taking apart electronics and I have replaced displays before but I am kinda clueless as to what I am looking for. Thanks in advance.

Edited to add pic of the panel:

Edit: Monitor completely torn down. There are 6 pin connectors on each end of a hard pcb led strip. Not sure how o test these or where to get a replacement.

Edited to add the model number of the led strip: LM41-00102A. Google brings back zero relevant results.

I think they are epoxied to the body as they dont seem to be removable and i cant see any screws. Edit: Googling “sjm-1 94v-0” is bring back some relevant results at least. Update, I reassembled the monitor as I am going out of town for a while and decided to deal with it when I return. After reassembly the monitor is functioning properly for the past 4 hours.

@bobmorales could be a main board video processor issue (less likely ) as well as a bad backlight array issue (more likely). you would have to take it apart and check the video board first. Make sure that the components etc. still look okay and nothing the is obviously damaged. A bad backlight array would also explain the “screen will flicker on and off” Once you have the back removed, let us know what exact model panel is in this monitor. Update (05/11/2019) To open the panel, remove the Philips screws for the frame. Start with the ones by the driver PCB. You should then get to disassemble the panel. Careful! There should be a few sheets of white “plastic” Those are diffuser sheets and need to be reassembled in the same order and the same directions. I mark mine with small stickers so I do not mess them up when I reassemble. Let me know if that makes sense

I would say try replacing the screen if it doesn’t work I don’t know how to fix it
