    Problems with an older LG plazma TV

    I have an LG 42PC1DA-UB Plasma TV. The picture had red and green dots and picture looks like an old VHS video. I checked the voltages on the power board all where set to specs printed on TV.I then adjusted the Vs voltage down 5 volts from specs. The red and green dots went away but the picture still looks like a bad VHS video on U tube. The video feed is good I had an other TV hocked to the same cable box and the picture was good. I also tried different input HDMI, Component, Cable,ECT all the same.

    Any thoughts and help would be appreciated.
    Thanks
    Chris

          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...

          Samsung UN55JU650DF network/streaming problem
          by howardc64
          Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.

          This TV runs older Tizen OS (updated to latest version, see pic) and have problems with network (wifi or ethernet) connection. The Tizen UI frequently switch to coax input source while changing content sources. . If no good signal (coax not connected, no prior antenna/cable...

          Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
          by Mgiffune
          I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started β€˜fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

          I ordered a supposedly β€˜new' Tcon board this time, and          ...
