    Panasonic TX-P42G20B display problem (no video)

    Hello
    I hope someone can help me with this problem in time to see the rest of the World Cup.
    My tv switches on as normal with no blink codes but a message no video appears on the screen.I hear sound and can use all menus but there is no picture. I have tried retuning and can find all stations with signal strength 10. Av button is set to tv. When I select Hdmi I can stream to the TV as normal from an Ipad and an Apple TV box and get normal picture and sound.
    Anyone know what is going on please.

    Sounds like it is not working with digital TV.
    I presume you've checked all channels -- none working?
    TV guide works, does red button feature work?

    Try a full factory reset. Hold the VOL/CH- button on the TV and press MENU once on the remote. A diagnostics screen should appear. Turn the TV off at the wall, and turn it back on again. It will behave as a new TV, all settings reset.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

      Hello Tom
      Thanks for the prompt reply. All channels are without a picture. As suggested I tried a factory reset but still no picture. Self check listed everything as ok. Red button works fine. Guide works fine
      Any other ideas please.

        Aerial plugged in correctly - check plug - socket on wall etc
        Has the tv been moved - check for stuck buttons on the remote.


        Later
        Try this?

          Overstrength signals can also produce no reception. had this happen to me requiring an attenuator.

          Strength may be 10, what's Signal Quality showing?

            Thanks for the posts selldoor and TW I will try them when I get home. Unfortunately my phone and broadband has now gone down and BT say they will not be coming to repair it until the 19th so I may not be able to reply for a few days. Pleas keep the suggestions coming.I have tried another tv on the wall socket and that plays ok so it seems the signal is ok. For some reason the Freeview is not displaying correctly on the Panasonic although streaming through hdmi displays perfectly.

              Problem with PANASONIC CF53 laptop after changing BIOS settings
              by AquaMan Ua
              Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

              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,...
