    Hi I have a 60pv450 with a messed up picture. I have attached a picture of the screen. It has a yellow back ground.sound works. I have verified the voltages on the power supply. The control card is flashing 3 fast and 1 slow flashes. Any help would be greatly appreciated.

      It's hard to tell anything with the picture being small. Is half the NO SIGNAL text missing and what is the screen like with a picture being displayed?
      Willing to help but I'm no expert.

          Try unplugging the ldvs cable that goes from the mainboard to the control board. On the control board there 2 copper holes marked r51 and r52. Put a piece of wire in each hole and then plug the tv back in. See if you get clear test patterns, red,blue,checker board,ect. If you do, the mainboard is bad.

              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...

              Need help troubleshooting a Whirpool control board (it's not the caps!)
              by UL161
              I have a Whirlpool Side-by-side refrigerator that is only a few years old and I am now experience a problem where the cooling coil valve that enters the refrigerator side is not opening consistently. (the freezer is perfect ice cold). I have found out the problem can be overcome by simply pulling the power for a few minutes. Upon restart it works for some period then randomly stops. In speaking with a tech they claim this issue is likely due to an issue on the main control board. So I decided to pull it and I thought one cap looked bad so I replaced all 4... I thought I had solved it but ~24 hours...

              LG 60PK250N ZA No picture
              by Fredrik_Bostrom
              Hi,

              To start with I think I have red every single topic on this forum about the No picture fault on this TV. Seems like a common fault but I just can´t find a match i other forum threads for my TVs fault.

              Symptoms:
              No picture, not even a little primer.
              Unable to check if I have sound since I don´t have any picture to navigate the menu to be sure I´m on the correct input.
              When connecting power cable it clicks just like it used to and the red standby light on the front comes on.
              When pressing the power button on the front it clicks like it´s...
