    So what are you getting when you disconnect each side of panel?
    I assume no responsibility for any stupid suggestions I might post.

          You sure your voltages are good? VGL?

              There are several other voltages that need to be there.

                At all measuring points which are marked the voltage is correct. I can't find the wiring diagram for t con Grunding 40 VLE 6142 C.

                  Only other suggestion is make sure you have those voltages on the tabs on side of screen.

                    Did you think to check the voltage on cof.

                      Help on Video Problem on Dell Inspiron 7459
                      by Spikeman
                      Hi, I'll tell you the story of this PC.
                      The PC was repaired because it had a shorted power supply. What happened was that the plastic covering the buffer battery positioned by the manufacturer on the capacitor melted, thus generating a short.
                      After the repair, the PC worked, I installed Windows 11 and I may have had some problems with the video drivers, but after a bit of tinkering I think I solved them.
                      However, the PC later presented the problem in the video shared very frequently.

                      The problem also occurs at startup, in the bios and when using it as a monitor thanks...

                      Grundig GV-250 Repair problem. (Video inside post)
                      by hugocarmo
                      Hi everyone.
                      I have the following problem.
                      I have a Grundig GV-250 VCR which has not been used for over 10 years. When I turned it on, the fuse of the PSU burned out, after being replaced it burned again, I ended up verifying that I had the bridge rectifier and the mosfet in short, I ended up replacing it, and I replaced all the electrolytics of the PSU. However, it started to behave strangely, as I will show you in the video that I will attach as a link.
                      In short, I ended up replacing all the ICs on the power supply CNY17G, TDA4605, TL431, TDA8137, TL082CP, AN3824K, L2720,...
