Hello everyone, I have a Samsung UE40J5200AW 40" Smart TV which seems fine at first, but if you look it creates a blue tinge on people's skin and other things.
-The whole story:
my father found it about a week ago right next to the dumpster, someone threw it away. He took it home and the next day I went ahead and had a look at it. The screen was surprinsingly intact and pretty much clean so I expected it to simply not turn on or something. After I found a power cord for it (both the remote and cord weren't there or were in the dumpster) I turned it on and much to my surprise it turned on and seemed to display the UI just fine so I connected the antenna cable, I was further surprised when I turned it on again and heard the channel that was on just fine but then when I looked I saw that people's skins and other objects had a blue tinge in some areas.
I took then to the internet and after being sacred a bit that it could be that some of the LEDs had bured I discovered the RBG option in the menu (I also found out how to factory reset which I did in case it worked out somehow) and experimented a bit. I found out 2 things while doing that:
1. only the red channel is having issues and
2. it seems to happen only at the edge of bright areas, when it starts to go darker, I got lucky and found this out because while experimenting a serie was playing behind and in one scene where there were no lights, and so no bright spots on the actors' skins, the image looked as if it was any other TV.
I kept digging around and found this forum, tried my luck searching for someone with a similar issue but no luck. Decided to register seeing how active this place is, hopefully I'll learn, help and be helped a lot.
Lastly I decided to open the TV and check the boards, they seem intact and are clean and dust free. I also connected my laptop to get controlled images to photograph for this post and the same thing happens.
My guess is that the chip that controls video output to display or something like that is slighty damaged but not broken.
-More to the point, some images and my hypothesis:
Samsung UE40J5200AW 40" Smart TV, there's a blue tinge in people's skins' and some other objects. Issue appears no matter the source (Antenna, HDMI...). After some digging around the web and experimenting with the device I rule out any LED or screen damage, and narrow down the issue to the red colour channel. It goes weird at the edge of bright areas, when luminosity changes. All internals seem to have no damage and are pretty much clean. Here I attach some images:
A low quality Samsung TV test image:
RED, GREEN and BLUE channels:
Close up of the image and same in the RED channel:
Inside and closer picture of the main board:
A GIF to exemplify the issue:
Sticker at the back just in case:
What I believe to be the issue is a faulty/damaged chip that is not quite broken but is sending bad data to the screen. I would like to narrow the issue down to one or a few components instead of chaging the board which, for all I know, could not even fix the issue.
