    In this TV, the replacement of the strips will only give them new ones in the matrix, and there will be no image anyway. :D

    And you can brighter, buddy? So far, the picture is there, but from time to time it does not want to connect to the error 6. 2 diodes are damaged in one of the 5 circuits with 10 diodes each. I assumed that this is why error 6 is.

    Yes. For this reason, and also because this invention has an error buffer like in old sharpas. It will get full and replacing the led bars is not enough :D

    So the question is how do I clear this buffer? If it's not "full" yet and it will light up through the service menu? And if it doesn't light up anymore, how?

    Hello, I'm joining the topic, I have exactly this TV on the table with exactly this fault.
    Could someone confirm the theory of colleague Wiesław about the error buffer?
    Even the Sony service center does not mention anything about it, moreover, they write in it to replace only a single strip of LEDs :)

    Best regards.

    As I wrote, the TV before the replacement worked only sometimes it did not want to surprise with the error 6. After replacing the TV strip, the TV starts 100/100 and works. The error counter shows 054.
    The method given by Col. Wiesław to reset does not work for me.

    To delete errors, you need to enter the service mode "info, 5.v +, power" and in errors of lamps on the remote control press 8888 or 0000. If after replacing the led bars it is ok, that is, the error buffer is not yet fully loaded.

Topic summary

Users report that replacing the LED strips may not resolve the issue due to an error buffer that can fill up, leading to persistent error codes.
