Telefunken te32160b29c10 - black screen and 7 blinking

    I have a telefunken tv that flashes seven times without displaying anything when it is turned on.

    the power board is a 17IPS11 (300413-R4).

    The capacitors are good, but there is a resistance (R145) of 0.27ohm that is shorted.

    Do you have any ideas?

    Thank you

    It is ok if the resistor (R145) of 0.27ohm is shorted. If R145 was interrupted then the power supply would not work anymore, and the LED would not blinking.
    Error code 7 indicates backlight problems.
    Check LED's and contacts between the led strips.

    I expressed myself wrong... I would say that if the LED flashes 7 times then there may be backlight problems.
    According to the scheme R145 can not be 56K.
    It looks worse, but it can be seen. R145 = 0.27R

    Blinking diode 7 czy 70 razy indicates nothing, a na pewno nie bckl, soft na main leży.

    W schematach Vestel jest pełno pomyłek
    W tym czujniku pradowym tranzystora polowego powinny być połączone równolegle dwa oporniki po 0.56 oHm

    Anyway, It's clear he does not know to repair something like that, when he says that R145 is shorted.
    Waste of time :-|

    If it is the software problem then first it should tried 17MB82 Core Update via USB Link

    I thank you for your reply but I would like advice on how to proceed.
    What do you advise me to do?

    It may be the firmware or backlight problem.
