Chosen Solution
I have a samsung TV model QN32Q50RAFXZA and the semi translucent piece of material in between the backlight and the lcd panel which I assume is a diffuser and or polarizer has faded streaks on it making those areas more translucent than the rest which results in a streak through the image. The diffuser panel is a drop in replacement that attached to a couple hooks. To no avail I’ve been unable to find even a part number so I can try to replace it. For the moment I have removed the material which results is a bit of a darker image that pops less and makes HDR content look horrible. I tried contacting samsung parts but they were not helpful to either order or even identify the part number. Can anyone find the part number so maybe I can find and order this part as the TV is no longer under warranty, but I’d like to get a few more years out of it at the quality of image it was designed to produce. It’s difficulties like this that make me support right to repair legislation with a passion.
@wheresmymedia you can use generic replacements. Check companies like this or check on here There are many more places that will even cut the sheets for you to make sure they fit. If you have the actual panel number, do a search based on that vs. trying to order from the TV maker.
