      impressive
      something obviously shorted and no fuse before it - or no fuse good enough!

      looking more - i recomend you inspect the tubes.

              The ballast cap probably failed and got so hot that started burning the insulation sheet and so on.

                      Problem with LG Plasma 60PM6700 - Random power downs
                      by theone111
                      I have an LG Plasma TV 60PM6700 for the past ~12 years.

                      In the last ~3-4 months I have been having some issues.
                      1. Problem: It started with random picture disappearing (sound still worked).
                        Frequency: Happened about once a week.
                        Solution: Had to turn off TV wait a few seconds before turning it on again.
                      2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                        Frequency: Happened about once a week.
                        Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                      3. Problem: TV shuts down

                      Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
                      by Zeonalbasta
                      i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
                      The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

                      Dell 15R-5521 keyboard problem (KBC?)
                      by SDNarcia
                      Hello, I have a Dell 15R-5521, with the problem that the Ctrl, Alt, Shitf and Num Lock keys do not work, I tested the keyboard with a keyboard tester and it is functional, I also got another new keyboard and the computer has the same problem with the same keys. Check continuity between the ZIF connector from the keyboard to the KBC and all pins are correct. I cleaned the ZIF connector and the KBC and I still have the same problem. I reinstalled windows just in case, and it didn't work. I updated the BIOS to the latest version A16 and there were no changes.

                      As additional information,...

                      Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                      by Bowline
                      My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                      Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                      My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                      The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                      I have tried multiple different Dell power adapters. My Dell...

                      HP F4180 stopped working please help troubleshoot
                      by flat-earther
                      I was doing a large print job with my HP Deskjet F4180, and after about 50 pages the printer stopped in the middle of a page and the black ink light started flashing.
                      So I went to refill the black ink cartridge with a syringe, but found out it still had a lot of ink.

                      I tried to print a page again but every time it would print only a bit of the page and immediately stop with the black ink light flashing again.
                      I tried two other black ink cartridges, and the problem still endured, so I knew this problem had to be with the printer itself.

                      I ran HP Print and Scan...
