    generic diffuser?

    i have a 65" samsung UN65TU700DFXZA. my kid sprayed cooking oil from a spray/mist bottle onto the screen (2yr old thinking she was cleaning). oil ran down and seeped under the bezel on the bottom of the screen. It appears to have soaked/wicked into the diffuser i have a light colored splotch along the bottom of the screen that grew upwards over a day or two.

    i have not disassembled yet but judging by the way it wicked up it looks like its been absorbed into the diffuser so i don't have a lot of hope of cleaning it.

    i checked Samsung parts site but they don't list the diffuser, i have found a number of places that seem to sell generic diffuser screen. could i purchase a generic sheet of diffuser and cut to fit? any reason why this would need to be original part?

    There is usually more than one sheet behind the LCD, one for diffusing the light then two polarizing filters.

      i assumed the polarizing filters were plastic and could probably be cleaned. any idea what the diffuser is typically made from? perhaps the oil is just wicking up between the sheets and not soaking into them and thus i could clean it out.

        Usually have the scan drive boards at the bottom, don't want them getting soaked with oil. I would carefully lay it flat to try to keep the oil from dripping down on them, really no choice but to strip it down and try to carefully clean it up, then maybe let it dry for a while before reassembly, it's a big screen and very easy to break, if it breaks thats ballgame. Maybe check youtube for backlight replacment to see how to dismantle if needed.

            M1 A2338 screen and touchbar issues after cleaning up liquid damage
            by jkruns
            Hello everyone,

            This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

            My patient is an A2338 Macbook Pro M1 (late 2020).

            It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

            Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
            by Ryan.man
            Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

            My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

            This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

            Problem

            This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

            iphone XS turns off when press on screen.
            by smic717394
            Hi,

            I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

            Samsung UE55JU6800K half screen dark
            by Chrissygizmo
            Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
            I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
