    Hello.
    TV Sharp Lc32Le600e no response to the remote control and local keyboard.
    After connecting to the power supply, the red LED lights up.
    You can not enter the service mode -V and input.
    I have measured the voltage coming out of the power supply and only 12V is missing on the PL connector.
    Will this voltage be in standby status? The diagram shows that the control signal PNL POW comes from the processor on IC7502 12VREG.
    It is strange that the TV does not report any errors.
    Do you have any advice on where to start?
    Greetings,
    Jack

    [quote = "jacek07"] You can not enter service mode -V and input. [/ quote
    And what do you want to look for in service mode? 12V is made in the power supply and you do not need to enter the service mode to find it.

    I do not see anything strange in this.

    You have to wait for a friend of fisk, something reported that he has some kind of workload or something. As soon as it appears, it probably sends a constructive link.

    Keeping these keys pressed, only switch to the network and not the other way round.

    Replacing the power supply solved the problem.
    I think about the subject as closed.

    And I do not, as you can see.

    Plate exchangers do not have to assume topics on the forum.
    Help them is also unnecessary! I would even say that it is not recommended. ;)

    Big problem, just in time for the module replacement.

    You had to say what the problem was and not comment on mirex.
    Fortunately, there are people on this forum who sometimes help and probably just because this forum is still functioning. Unfortunately, from what you can see, there are less and less of them.
    Greetings and I wish you a Merry Christmas.
