      LG 50PG20-ua Plasma TV repair help
      by Ted29946
      I'm new to this so I hope I'm doing it right So....I picked up a LG 50PG20-ua Plasma TV (Someone's throwaway pickup) First power up no picture or sound

      Found power board to be bad and I repaired it. (Bad caps) Now all power volt readings are good. Still no picture or sound. I plugged in power cord, no click and the standby light on the on/off button comes on blue as soon as it is plugged in and does not turn off when button is push. I then pulled the main board off to look at it better and the initial inspection (front and back) I cannot see anything bad. Before I put the board back      ...

      Samsung PS51E550 Plasma TV
      by ArMaaN376
      Hello,
      I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
      Opened TV cover & observed foll
      a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
      b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
      c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
      How to confirm Y -Buffer board...

      Panasonic plasma TX-P42ST50 - 6 blinks
      by jm1234
      Hi,
      anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
      It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
      I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
      I checked that board for any obvious faults...

      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...
