@eyalsaad how faded? what have you tried? what have you checked? Washed out images are usually related to a bad gamma ic.
Update (05/02/24)
@eyalsaad that is correct. The OEM's like Samsung, Sony, LG and all the others, do not want us to repair. They want us to buy new and toss the old devices in the landfill. Never, ever expect any help[ for any repair from any of those companies. They are strictly driven by greed and do not care about anything else but $$$
Anyhow :-) check driver boards for your LCD. Those are the long skinny boards where the two ribbons from the main board connect to. Correct me if I am wrong,but I do not believe you have a dedicated T-con board. Your TV model has a integrated T-con "board"

@eyalsaad ok, you can now add more information to your Question buy editing it. You can also add images. The more we see and the more detail we have, the more likely we find a way of fixing the "Beast"

Same as pictures above, I can see the image but the white light over power it. I was looking for a board schematics so I could locate the gamma ic with no luck. I'm capable of soldering smd's but no schematics 🤷♂️
That is correct actually I have 1 ribbon cable and 2 pcbs that are jumped together. Give me a second ill send a picture
Ok I do have an ic chip on one of the pcbs let me get the number
@eyalsaad If you have a number or even some good pictures of the IC on those boards, that might help. Of course, it is also possible that the IC is on the main board. Let's see if we can figure it out.
Added some pictures

@oldturkey03 so i got another main board with the same results. i took the power supply off the board to find that I believe that is were the screen drivers are. as i said before you can see image but the white light is over powering it. im not a TV buff so i started investigating the components, all appears to work fine. the downside is the IC's are not marked at all so i have no way to identify them :(. im going to try and get a working power supply and see.
@eyalsaad I hope it works. I just wish we could get the schematics for the driver board or at least find that Gamma IC.
originally posted as a comment to Samsung QLED White/Washed out screen - Main Board or LED Driver Board? Reference made to any white screen with washed out images refers to look alike on that question.
