    Sharp LC-C4067U Video problem

    Aloha Folks!
    I have the above Sharp TV that had a blown out T-CON board (blown fuse, shorted bypass cap and cooked chip). I put in 2 replacement boards, purchased off eBay, and I get the result shown in the picture. Pressing "Menu" or any other buttons does not change the display.
    Is this a main board problem?
    Mahalo!

      Turns out it's a bad panel. I found a melted/shorted section on one the ribbon cables going to the panel.
      Another TV for the recycler! Too bad!

          I just wanted to say... by all that what is / was blown... the panel would be most likely bad.

          You could have tested the LVDS with an oscilloscope while turning the menu on off all the time. That could have told you that the main board was actually O.K.

              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,...
