    Technika lcd42-207 wont stay on (even with new power board)

    The problem started a while ago, The tv sometimes wouldnt turn on (from standby) or would turn on from anywhere from 5 minutes to an hour, We left the TV turned off and unplugged for a few months and then started using it again the other day, Both times it turned on for 45 minutes before going back to standby.
    After looking around the internet we got a new power board for it, Put the power board in (100% correctly wired up) and turned the tv on,it turned on for a second and went back to standby, so is now doing the same it did a year ago.
    What else could the issue be?

    Ive looked over the internet today and seen a fair bit about inverter boards, However if its the inverter board would the whole tv turn off?

    The company I got the power board from think it could be the main board? They did say they will happily refund/exchange any items brought with 30 days.. My issue is I dont want to have to keep on messing about ordering and returning.

    Thanks

      Do you have a multimeter and soldering equipment?

      Welcome to the forum-
      We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back (in the same orientation) and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

      Please do not post inline and offsite as they slow down the loading of pages.

      Examples of what is needed

      It will be useful if you can say a bit about yourself - skills tools etc.

      Decide which boards you are going to use then do pics.

      Normally if it is just an inverter fault the tv continues with sound and a very very dark picture
      but I guess it would depend on the severity of the fault

          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          by Tynan Dill
          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
          by howardc64
          All left and right refers to looking from rear of TV (or looking from front with TV upside down)
          • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
          • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

          LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
          by Hakuu
          Hi There,

          This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

          After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

          More Details

          TV Model - LG OLED77G1PUA

          Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

          Panasonic TC-P54VT25 No image. A or D board?
          by canadaboy25
          I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

          The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

          I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
