    METZ 65MUB8000 picture noise

    Hi,
    I have this 65 android tv that switches ON ok but after the LOGO is displayed a lot of noise starts appearing across the picture.

    After an overnight OFF it takes a little longer for the fault to appear. I have tried to take advantage of this by heating up the mainboard and TCON while keeping the display cold. But have inconclusive results.

    Tried removing either panel Tabs but with 1 tab only I get no picture. Then I tried the tape method on a small portion of each tab, moving the insulator left to right, but again didn't find any correlation.

    Am not sure how to tackle this any further. Am not yet convinced if the panel is the culprit. Am searching for Service mode to do an initial factory reset.

      Samsung LE40F86BDX (model 2007) noise in picture
      by tracid1987
      Hi

      I have this TV bought back in 2007 and used it for playing on PS3 for 4-5 years actively. After then it was barely used. It was mostly in stand-by mode or plugged out of mains completely for years. Today when i turned it on i have noticed noise in picture on two different locations of the screen. As you can see on the photos (see attachments) the noise is only in a small rectangle area, and if you look at it closely you see that one noise rectangle area is at the upper left corner of first half of screen, the other noise rectangle area is at the upper left corner of the second...

      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)...

      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...

      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...

      Removing electrical noise introduced by fan
      by tony359
      Hi all,

      I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.

      Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
      1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
      2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line....
