    HITACHI U50KA6150 LED TV - Turns on, BKLT ok, no picture

    Hi there

    Got this TV set to check.
    HITACHI U50KA6150 LED TV

    The tv turns on ok, I can see on my PC that it detects the screen and I can see it on the screen settings, but theres no image.
    Backlight is present. screen not broken or shattered.

    Its this clearly a TCON or panel issue?
    I dont think it can be a board issue, but im not a TV expert

    Any inputs but someone more experiences is welcome before I disassemble the device or try to find a new tcon.

    Cheers

    It sounds like a panel fault to me. Check that your 13V is getting to your TConn/ open cell.

    Majority of the manufacturers link the panel and open cell by variant in modern devices, this might be a difficult one to diagnose.

    I don't have a ton of experience with Japanese manufacturers but based off my experience on the Chinese and Korean manufacturers; a blank display is the open cell, a discoloured image is the tconn board.

      Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
      by KYBOSH
      Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
      No picture but you hear the TV static (white noise) playing loud and clear.
      The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
      But it seems they didn't get too far and just left it.

      When I first took a look I was amazed at how pristine the inside looked.
      Its as if the TV had been in a time capsule.
      Caps looked like they were just pulled off the self.
      Copper coils had no sign of corrosion on...

      LG 32LG3000 TV, three red light flashes, then the backlight turns on, but no picture
      by ItepK
      Hello everyone! I've found this television, and I began troubleshooting it.

      First, the television kept rapidly power cycling. I've warmed up the capacitors with a hairdryer, and after 3 dimmed red blinks, the backlight turned on, then turned dim, and no picture was present on the screen.

      I believed that this was caused by a bad power supply producing insufficent power (I've measured 3.5v on the 5.2v rail), so I've blindly recapped the board.

      After the recapping, all the voltages stableized, however, the issue in the title still remains.

      I could...

      T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
      by Tr0ll
      Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

      The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

      Original T-con:
      Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

      First replacement T-con:

      I thought it might be t-con and ordered new t-con from china(supposedly tested)...

      55" QLED QE55Q60T Turns on after 1 minute the picture goes bad and get in boot loop
      by burbutsalos
      Hello ,
      The issue with this set is that it turn on just fine and after a minute or so the picture shows either vertical lines or turns half black and from that point on starts a boot loop.
      If a let the unit to cool down for a minute the same pattern starts again. i had exactly the same mainboard as a spare and replaced it but nothing changed.

      Any ideas what to check?...

      SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
      by JJAAMM
      This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

      Problem
      TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
