    scetre 32 LCD - works for 5 minutes then loss of picture

    Man, these LCD and Plasma TVs are just plain problematic.

    My sister 32 inch LCD sceptre has a bad solder joint I think.

    It comes on with from red light to blue light. Everything works for about 5 minutes and then the screen goes dark. blue light stays on.

    I unplugged the TV for about 10 minutes and it comes back on the the picture goes away again.

    Changed out the inverter board but that does not appear to fix the problem. how do I determine if the T-con is working properly or not?

      By replacing it with a known good board.

      With all due respect*, you are wasting a lot of money with your troubleshooting approach. Does the sound work after the screen goes dark? The tcon should not affect the sound. Do the backlights go out (there is usually some light leakage even if the screen is black).

      ABOVE ALL, are the output voltages out of the power supply correct after the screen goes dark?

      * Not much.
      For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

      Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

          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)...

          KDL-70R550A Peeled off LCD Tabs on left side and perfect picture for 5 minutes
          by Davidhames
          Hi Guys,

          Thought I might try and seek advice on an issue I am having, I got this SONY tv for free that was having some dark greenish colouring, I replaced the T-CON and too my suprise the TV would not boot - I would get 5 blinking red LED lights. I dug deeper into this forum and someone mentioned the fact that it might be the tabs that connect to the LDC panel, and peeling them off should bring back a clear image. I tried this on the side of the T-con that was causing the tv to not boot when plugged in (left) and wow a perfect picture and was booting up fine! All was well and good...

          Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
          by TR103
          Hi, I have a Samsung UE50TU with:
          - sound and backlight, but no picture
          - when it arrived, it had a picture for a few seconds
          - it keeps rebooting
          - without ribbon cable between the two panel boards, it does not reboot but I have no picture
          - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
          - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

          - without cable between mainboard and lcd panel and with a jumpered...

          Neptune mixer model 611 - Works for a few minutes then fades out and distorts
          by Zonzi
          Hi there !

          This is my first post out there, glad to be part of the community.


          I was gifted an old analog mixing unit (from the 70s) by a good friend. It's a Neptune Audio Mixer model 611, 6 channel mixer with :

          -6 XLR inputs wired hot to 3, and 1&2 to ground (which is already a weird start. You can see this in Picture 3, and all sockets are what I understand to be common ground, as there's a long wire connecting all XLR grounds together. Besides, all Hot are connected to the other pins via a cap with the marking 24 102k)
          -6 unbalanced...

          Sony XBR-43x800e TV had sudden loss of picture
          by beenthere7
          Sony XBR-43x800e TV had sudden loss of picture. Screen is dark except for backlight. Sound is present. Main and T-con boards have been replaced (T-con twice from sets with reportedly cracked screens) with no improvement. When one side of the cable between T-con board and display panel is disconnected (call it the “bad” side), the corresponding half of the panel is white and the other half black. When the other cable from the T-con board to the panel is disconnected (with the “bad” side cable reconnected), the whole screen remains black except for the backlight. I've tried blocking several...
