Show me where the 6th error indicates that the motherboard is faulty; usually the 6th error is related to a faulty backlight.

Good morning, I have already forced the LED bars to be powered on, but the signals from the main board that go to the display disappear, (there are 4 LED channels, all with the same current when powered) the service manual says that when it blinks 6 times ; If on pin 36 of cn9901 the voltage is less than 3V it is the LED power supply, if it is higher it is the main board, in this case I have 3.2V Thanks anyway for trying to help Manuel JoaoComment

I can't update, the brand appears three times and then flashes 6 times in red, I don't have a tool to reprogram the nands which I think are responsible for the failure

Hi,
I have been given a SONY KD-43X8305C Android based 43" 4K TV.
It received a software update which failed and then failed to boot after.
I have tried holding Power and Volume down (-) then applying AC power, multiple times, with no success.
The backlight is off, the main status LED is Off, the Mainboard heat sink gets slightly warm if left on for more than 30 minutes, showing it is getting power.
PSU has normal outputs. Screen appears blank even with a torch test and no start up sound from Android is heard when powered on.

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,... -
Hi, I'm hoping someone can help me with this issue before I give up on this TV.
In short, I replaced the T-CON board due to an error code indicating that was the problem, after which it flashed a green and orange LED meaning software update required. I cannot get the tv to do the required update via USB, so I am stuck.
Here is a rundown of the symptoms and the steps I have taken to troubleshoot:
I inherited the TV with the symptom that it would turn on, then turn off after 5-10 seconds and a red LED flashed 4 or 5 times. Sometimes it would be 4, sometimes... -
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.

Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
