      Philips 8200 series 65PUS8204/12 stuck at Philips Logo
      by G33RT
      Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

      It does power up when pressing the power button.

      I already try the power button while plugin the plug with no result.
      Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

      Could this be an PSU or eMMC issue ?

      Philips 42" TV 42PFL3603D/F7 clicks but No LCD Backlight
      by jason123
      Hi folks,
      I'm suspecting the actual CCFL or EFL being bad, just not sure how to test, but would like to confirm.

      TV clicks upon plugging in AC. When I press the PWR ON button, clicks again.
      LED on the Main board comes on green (Assuming some diagnostics), Blue LED on the TCON comes on also when I turn the TV on, but turns off about 30 seconds later.

      3V3 ST is on (3.26 V)
      Standy 3.3 V (off) when I press power button goes to 0.16 V
      12Vssb is 11.75 V (on), 0.18 V (0ff)
      +12Voud is 13.8V (on) ~ 0V off
      -12Voud is -12.4 V (On) ~0V...

      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...

      Philips 58PUS6809/12 doesn't turn on - LED turns on for a second and TV clicks
      by Tyrmas
      Hi all!

      A few days ago my TV suddenly turned off while watching Netflix from my media PC. Only connected cables were HDMI and TOSLINK. It immediately started doing this loop where the power led turns on for a second and then turns off. You can also hear a click inside the TV every time.

      I tried the easy stuff first like disconnecting everything including the power cord but that didn't fix the issue.

      Now I opened the TV to check if there are any bad capacitors but as far as I can tell, they look okay.

      I've attached a few pictures and...
