      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...

                      Lenovo T580 - LCD Panel problem - error 0288
                      by perzyk23
                      Good morning,
                      I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....

                      Asus Zephyrus M16 / GU603ZW problem
                      by lazaro.089
                      Full name/ Model: Asus Zephyrus M16 / GU603ZW-M16.I93070T
                      CPU: Core i9-12900H
                      Onboard 8GB DDR5 4xMT60B1G16HC-48B:A

                      Problem: This laptop was brought to the shop with the board already meddled with. Last technician (maybe without the right tools) removed an electrolytic capacitor (PCE9203) sensing resistor (PRS9801) and probably flashed both BIOS (U2802) and VBIOS(U7802).
                      The laptop's behavior is: When connected, it tries to power up. CPU powers on, and (allegedly) the power sequence finishes and goes to S0 (PLT_RST = 3.3V). It consumes 600mA, ramps up to 1.100 A and...

                      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,...
