    Sony KDL-60EX645 6 Red Flashes

    I have a Sony KDL-60EX645 that runs for about 30mins then shuts off and starts flashing a code 6. After about 10mins it will turn back on.

    I am fortunate enough to have two of these tvs.

    1. I have swapped all three boards separately Main board, Power Supply, T-con...

    2. I then took all off the broken tv's board put them in my working tv and the working tv works fine! The problem did not move with boards.

    3. I then uplugged buttons and wireless adapter(grabbing at straws) no change in failure.

    I am leaning toward a bad backlight.... If this is the case how could I find the short? Maybe its a cold solder joint once it warms up? Can this be fixed?

    Thanks

      Sony OLED XR-77A80J - 5 Flashes But Turn On After Hard Reset
      by odie34
      I am a hobbyist (not a professional) so please be gentle...

      I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)

      I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen. There's not a lot of detail on the setup screen but the picture didn't have any distortions, so at least a cursory examination suggests no physical damage to the screen. The set appeared to be working normally, but it shut down after about 15 seconds,...

      Sony Android TV KD-49XE9005 4 red flashes
      by Dangerousk
      Hi there

      Have Sony KD-49XE9005 that has been working fine for some time now. switched on this AM and after a few seconds screen blank and red LED flashing 4 times. Tried resets and all responding as expected expected and after booting up, after few seconds of displaying normal broadcast picture, screen goes blank red led flashes 4 times in sequence.

      Anyone have schematics/service manual for this series. have checked the obvious items and caps test OK, voltages etc appear correct onwards.

      thanks

      Sony OLED XBR-65A8G 4 flashes
      by Glaval
      Hello, my Aunt recently gave me her broken Sony XBR-65A8G OLED after getting a replacement. It had a 4x led flash error, a replacement T-con didn't fix the error but with helpful info from this forum I found one of the smd ceramic caps on the panel pcb (C575/C378) on a 24v line was shorted to ground. I removed that cap and the tv turned on without error. It still had a black screen with the original t-con back in it, once I put the replacement t-con in it finally had a picture. After doing a panel refresh it had a very good picture but with a few vertical lines for some scenes. For owners with...

      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...
