    FIXED: Sony KDL40U2000 4 blinks

    This is the error code showing problems with the PSU/Inverter/lamps.
    In my case this was a very easy fix.
    After stripping the TV:
    -No signs of swollen caps. (Sony at its best)
    -Voltages Ok.
    -No blown fuses in the inverter.

    I had to unplug every bulb, clean the connector with alcohol and plug back.
    Tv started immediately, and luckily didnt want to enter service menu to reset (i dont have a Sony remote in my workshop).

    I applied hot silicone at the connectors just in case.

      Sony KDL-46BX450 Inverter Troubleshoot Logic
      by caseyjay_48
      I am currently on a troubleshoot of 46” Sony KDL-46BX450 tv. I came back from Washington to Texas on medical emergency and had to leave all my tools up there. All I have is a couple of screwdrivers and a dvm. I wish to ask the community a troubleshooting question. Please forgive stupid questions as meds I am taking produce brain fog.
      I have well maintained Sony KDL-46BX450. It went black one day. After turn-on, I get solid green light and Sony logo in screen center for about 1-2 seconds, then black. No blinking LEDs, no hissing. Flashlight test shows screen characters dimly viewable,...

      Sony KD-65A1 Repair – 4 Red Blinks Error
      by AK_777
      Hi everyone!
      I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

      Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...

      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...
