    kdl-55w700b 5 blinks - easy fix

    Just a quick success story that may help someone down the line.

    Had a kdl-55w700b come in with 5 blinks. Tested power supply and (what im going to call) input filter board. Everything checked out. Did the normal test to pull the main board cable to test backlight function. The cable was in the socket but not clipped in to place.

    Clipped it back in, unplugged and replugged power. Hit power button. Its alive.


    Owner says he bought it new and was never inside it. So a slip up from Sony QC it seems.

    Well, something for you to check before going any deeper down the Sony rabbit hole.

      Nice catch. I have here a Sony 70x690e that had a very similar fault just harder to get at - one of the ribbons connecting the outer lcd driver boards was clipped in but visually crooked. Worked fine after resetting the cable and lock.

              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...

              Sony XR-55X90J 4 blinks
              by Nicktronic
              Hey guys, got this Sony that turns on momentarily and then goes black with 4 blinks of the standby light. I can't find a service manual, but best guess was the Local Dimming board based on a similar TV saying LD_ERR or BCM_ERR. I found a replacement, but it didn't work. Before I put more money into replacement boards, Im wondering if anybody has seen this issue and what worked for them, or has the service manual for this specific TV.

              Thanks!...
