Helo. I have a Xiaomi 4a Bezel less TV. After a year of usage the screen showing artefacts:
I think the color also feels a bit washed-up but I’m not sure, I have stopped using it because I’m too afraid to cause more damage. Can someone help me if this is a screen, t-con or main board issue? TIA Edited: adding images
PS: the photo of tcon is rotated 180'
Leebid this is a bit hard to see but it appears as if the lines are not all the way from top to bottom. Lines like that are usually caused by memory errors on the main board. You are right about the color looking washed out and not color accurate. Based on the lines I go with a bad main board first. The T-con could be having a faulty Gamma chip or faulty voltages. We really would need to see what vboards your TV has. It may actually be a main board with integrated T-con function on it. Remove the back cover and post some pictures. First one should show the complete layout of the TV boards including the ribbon cables. Then the individual boards. For that, you will need to edit your QUESTION and then use this guide Adding images to an existing question
