    Tv i-joy

    Hello, we have a tv i-joy without sound.
    The board is this HK-T-SP7050V48
    The ic of audio is tda 1517P.
    I have checked the tension input is ok on that ic, but it hasnt audio signal on input.

    Which is the next step to check?

    Thanks

    Have you tried checking sound using the headphone output if there's one. What is the voltage you have on pin 7 and pin 8 of the TDA1517P
