    Vizio M3D550KDE Black screen, rust problem?

    Hello,

    First time asking a question, so please stay with me.
    Purchased the above Tv 2 days ago and decided to try and fix it. Screen is black, but lit up. Top half of the screen is not as bright. Powers on, but there is nothing on the screen.

    Took the back panel off and I noticed some weird rust or corrosion where the tcon board attaches to the panel.

    Does that mean the entire screen is shot, or are there pieces I can replace? I don't want to buy a bunch of parts to try and fix it if the screen is the problem.

    Oh, and no sound.

    Thanks for your help!

      Here is a picture of the ribbon. That's the tcon board at the top of the picture.

        Here is another picture of the ribbon. Took the TV apart and found that the ribbon leads directly to a board that's wired into the screen. Assuming this means the TV is toast.

          Looks like liquid got in there and shorted it out. Beyond repair.

            Crap.
            So my best option would be to part out the boards? Just not sure where I'd sell them.

              Death by windex.. ugh.
              Sell them on ebay,you will get decent money for the main board and t-con.
              Could strip the panel and sell the LED strips too.

                Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
                by HTR-Informatique
                Hello,

                YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

                I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

                On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

                I also changed the screen because the PC fell and the screen was broken.

                I changed the battery with a new and original battery.

                I also had corrosion/oxidation on the...

                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....

                Acer Aspire E5-574-52RH - black screen
                by DaniK
                Hi everyone,
                I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.
                Laptop came in for a SSD upgrade, took everything apart to install the SSD.
                Everything started after modifying BIOS settings to boot UEFI instead of Legacy.
                Laptop works fine, i installed windows 10 and drivers/updates, everything works ok(when it works)
                The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image

                Symptoms are:
                - random black screen after displaying Acer logo...

                Vizio M60-C3 black screen
                by paqman
                So our beloved M60-C3 up and died the other day. I was not there, my wife mentioned that it came on, displayed the logo, then showed the right half of the screen white and fuzzy, with the left half of the screen ok. However when I got around to looking at it, the screen would not come on at all. The indicator LED will come on, then dim a bit. After a while, the LED might blink a bunch of times. I can't get it to be consistent to do that.

                So I've got the back off and am checking voltages. The capacitors on the power supply board visually check out. No bulges or anything. They all show...
