    Might be a candidate for "tape cut-off method"

        Forgot to attach a pic last time. Also when the tcon came of the side of the screen by the power buttons got pretty hot. I'm guessing I fucked it, not sure why I bought a broken tv anyways when I usually get them for free.

            I swapped the ribbon cable from the other side and part of the screens circuit board caught fire and a trace burnt, she's fucked. I think I fucked something up when the tcon came off the the tv while it was powered.

              You mean you only get a quarter now, when last exact setup gave you half a good display?

                            I'm done. Whatever happened to the tcon it gets hot as fuck now, so even if i fix the traces on the screen they'll just burn up again.

                                  Hello,

                                  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....

                                  Hello everyone !

                                  My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...

                                  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...

                                  Hisense H49M3000 PSU buzzing + Black screen after 20min
                                  by EUWest
                                  Hey Folks just got another Hisense with an unusual Problem.

                                  After plugging in its starts buzzing on the cold side. Could not located it 100%, but seems like transformer/capacitor.

                                  TV has 1 horizontal Line, often static. After 10min screen gets flickering and after about 20min screen gets Black while Sound is on. After turning off and on screen appears back for about 5min and then went Black again.

                                  I checked LED Voltage:
                                  While Screen is on about 115v
                                  While Screen is Black also about 115v
                                  LED Connection unplugged also 115v
                                  ...
