    Sony Bravia KDL-46HX800 6 blinks troubleshooting

    Hi fellas,

    I'm trying to troubleshoot a Sony Bravia KDL-46HX800 and have been looking around for the past couple of days for a solution. I have found the Service Manual, gone through it, and would now hope to get a second opinion on how to interpret the Manual's instructions.

    The TV turns on normally for 27-31 seconds with the picture coming on fine, but then it shuts down automatically and gives 6 blinks of the standby LED. From the service manual this indicates a Backlight Error (picture 1).
    Testing the voltage at "PANEL_FAIL" (which from cross-referencing the schematics appears to be BL_ERR on the BAL board), I'm getting 3.25 Volts when the TV is on and 0 Volts when it shuts down automatically.

    When following the flowchart and taking the BL_ERR voltage reading of 3.25V would I be correct in changing the G* board first, and if that doesn't work the T-CON board next? Also I am assuming that the G* board is in fact the G4E board (looks like the power supply unit) referred to in the picture 2. Is this correct?

    Cheers!

              given that it has a samsung led driver board,I would not be surprised to find some failed led's in the set nd that the bl-err is a legit responds.

                  Sony XR-77A80K 5 Red Blinks Troubleshooting
                  by Dogindelusion
                  Hi everyone! I am a new member and am new to electronics repair. I have a background in electrical engineering, but little experience in electronics.

                  I have a Sony XR-77A80K which will not turn on and has 5 blinking red lights in the stand-by light. I had previously done a forced factory reset, which removed the error code, and the TV regained functionality for a few weeks. I repeated the factory reset and again regained functionality. This happened a few times until I so I had to begin troubleshooting the error.

                  Observations:
                  1) I noticed I was not getting...

                  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 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 bravia kdl-43w755c - boot loop
                  by justin35
                  Hello,
                  i have this sony bravia kdl-43w755c which boot loops. After sony logo, it shows the android animation loading then it restarts…
                  from what i read online it looks to be an emmc issue…
                  i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
                  i took out the board and say an samsung 16gb emmc
                  i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
                  i could try to put one instead of the 16gb one, but will it work?
                  where do i get the software from?
                  any help will be much appreciated!...
