      Panasonic TH-50PX8EA Black screen, only relay clicks
      by Rensiee
      Hello,
      I have been reading a few threads on here regarding Panasonic plasma tv's. I've found one thread which explains the same problem as mine, unfortunately the thread has not been completed.
      I got a free tv (TH-50PX8EA) from a friend which shows no screen. When plugged in only one red light shows up and when pushing the ON button, the red LED turns of and will only turn on again when pressing the ON button again.

      When plugging in the TV i hear two relays click fast and after a few seconds the third relay clicks.
      I have measured the voltage in the VSUS line, which...

      Sony OLED XR-77A80J - Initially dead, now 4 Flashes
      by thstuff
      A) TV initially dead
      B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.
      C) Was able to perform a Reset from Settings menu and completed out of box configuration.
      D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
      E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical...

      Samsung LN46b530p7f – relay clicks and backlight cycling, sound OK
      by momaka
      I got this TV a little over a year ago from a coworker from my previous job. It’s a Samsung 46” TV, model number LN46b530p7f.

      Problem:
      Backlight cycles On and Off.
      Basically, when the TV is turned On, there is a relay click heard from the TV PS board. The relay cycles On and Off 4 times in about 2-3 second intervals. Each of those 4 times, the backlights also cycle On and Off with the relay. The screen TFT isn’t cracked/damaged and appears to work - I can see a “no signal” image when the backlights turn On briefly – though the image is a bit dull/dark....

      toshiba 46xv555d relay clicks
      by samtron786
      Hello
      The red and green LEDs both light up and you can hear the relay click. (no picture, no backlight, no sound)
      2-3 seconds later the relay will click again and only the red LED will stay on.

      I would be very grateful for any advice or a little help.
      circuit diagram?


      Thanks very much

      Garage door RX unit (Cardin S38C) does not short relay to send opening signal
      by CoinCoin88
      Hello everyone,

      I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!

      Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver...
