    Sony KDL-40P3600 3 blinks

    Ok, got this tv some time ago, the fault was 3 red blinks upon plugging it in. 3 blinks for this model means power supply problem. Tested voltages on PS and 12V wasn't there. Stdby was ok.
    So started to test PS for shorts and found that 12V line that goes to mainboard was shorted. Well, not 0 ohm short but somewhere arround 260 ohms . Started isolating components on 12V line and found CXD9969 which had 260 ohms between GND and VCC pin.
    Ordered it from UT source, came today, soldered it in and TV is on and working

    So, no problem wit this set, just wanted to share this, maybe this info will help someone to fix their TV with same error.

    Used manual for 40s5600 because i couldn't find any for this particular model, but it is the same chassis (sony_kdl32_37_40s5600_chassis_ex2n-peppermint)

      Thanks, this was really helpful. I couldn't find the service manual for a KDL-32P3600 anywhere.
      Eventually I ended here, this service manual was valid for this TV model also.
      In my case, there fail was red led 4 blinking 4 times.
      Solution was to replace blown mosfets and fuse on the inverter.
      Regards

          Sony XR-55X90J 5 blinks
          by matwan
          Hello,

          I have problem with SONY 55X90J. After several check status is as below;
          1. Running power board as stand alone:

          TCON_12V =~ 12.6V
          EVDD V On Max 24V= 19V.

          2.          Running power board with TCON as stand alone:

          Effect as below, attched.

          3. When bottom LVDS cable is disconnected no blinks, but of course no TCON 12V and EVDD.
          "I'm almost sure it's a defective panel, but maybe someone has encountered a similar issue on their screen.

          Best regards....

          Sony XBR-75X940E intermittent 6 blinks error code
          by GoodCapDude
          Hi everyone. First post on Badcaps!

          I am trying to fix a Sony 940E from 2017 that either starts normally (and works perfectly until turned off) or goes straight to the 6 blinks error code without showing anything on the screen. It is frustrating to know that it can still work perfectly but is barely usable because of the difficulty starting it up. I am willing to try to short the BL_ERR but I would like to avoid that if possible. Does anyone have a view on this? Thanks a lot....

          Sony A1e 5-blinks help
          by jchon
          Hi I'm new to trying to repair TVs, but I saw a broken OLED offered for a reasonable price and thought I'd try my hand at it.

          I found the service manual, which was critical to know where to probe.
          https://www.manualslib.com/manual/20...1e-Series.html

          With it I was able to determine that my DKA board was bad, when P_ON#1/2 gets enabled REG_12 on the DKA board collapses. I'm assuming one of the downstream regulators has a short, but I couldn't work out which rail/component and replaced the DKA board entirely.

          Unfortunately the 5-blinks...

          Sony XBR-65X850D 2 Red Blinks
          by Nicktronic
          Hi all,

          I have the subject TV and it will work normally sometimes but suddenly go black and give the 2 red blinks blink code. When this happens, I check the power supply board voltages and all I have is the Standby 3.3V and BL_ERR 2.2V. When it's working normally, all power supply board voltages look normal and stable. I've checked the backlights with a tester and they all test good. I've also read that the 2 red blinks is a faulty power supply board, so could it be throwing up an erroneous BL_ERR?

          Any Sony experts out there that can help??...

          Sony 75X9400E TV.. 5 Red blinks
          by dumbdd
          I was using this TV for 5 years before it stopped working. I like this TV and would love to fix it myself.*

          When I press the power button, the white led comes on (sony calls the module smart core) and then it switches over to 5 red blinks. No screen, no backlight, no relay click, nothing. I have disassembled the tv and found the service manual for 75x940e online. The manual suggests a faulty power board, TCON or the panel.**

          The standby pin is at 3.3V. Fuses on the mainboard and TCON are fine. Caps on TCON also seem to be fine. When I turn on the tv the white led...
