    No picture from LG 50PS60 Plasma TV

    Y'day while watching a program on TV(LG 50PS60 Plasma), there was a buzzing noise from the TV for around 5 mins.. then it went away on it's own... today the buzzing noise came back for 2 mins or so & suddenly the TV went blank (no picture.. sound still on)

    So I rebooted the TV & tried again. I heard the click of the switch on, the small display light turned blue & then turned red again. The screen did not light up at all. Tried waiting for 2 hrs with tv off & tried switching on again. Still no picture.

    Opened the back & noticed the following while switching on. The LED R445 on the CTRL Board comes on green & then stays on. The LED R448 does the following sequence (all in green): 1 normal blink > 1 more normal blink > 1 long blink > 1 short blink > 3 normal blinks > 1 long blink .. and then the same sequence goes on & on…. All this while the display light at the bottom has turned red & there is no display on screen.

    Also looked for any obvious burn marks or bulging caps or leakage from any components. Found none. Also checked all the fuses I could see. All okay.

    Any ideas anyone?

      Panasonic ZT60 plasma tv with strange behavior and 8 blink code
      by cloo
      I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
      It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


      So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
      After doing a factory reset this problem was gone and the picture was back to...

      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...

      Trying to Save - LG 60PH6700 60-inch plasma HDTV - Powers ON but no picture
      by KYBOSH
      Saved this beast from the landfill this weekend.
      Manfactured July 2013 in Mexico.

      I love working on plasma TVs.
      Its been a while but I was lucky enough to find 2 this week.

      The TV powers on and stays on but no picture. Havent checked for sound yet.
      No bulging caps although the insides are pretty dusty and the boards are discolored from many years of high heat.
      Will start troubleshooting tonight.

      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...
