    Hi my friend
    when u ask for help for tv or monitor or whatever please write down the model number and chassis number if available for the device u are asking for .
    so , please write the model number and chassis number ( preferred chassis number) of this LG tv to get more help and response .
    by the way , if the power cable is short it'll cause a problem to the home electric system and will never carry power to the tv to get the led bliks and i don't suspect the fuse as well as u have a power in ur tv .
    Kind Regards

    hi
    how come that the power cable has a break?
    he said that "the tv the standby led of the tv blinks for a few secnods and then automatically off"
    this means the power cable is ok and the tv is already powered by the power cable , there's another problem here and this may be a power supply problem or a horizontal stage problem and it needs more further inspections .
    Regards

    lg tv circuits

    simple, start at the source and work upwards.
    eliminate the power cable, the fuse and the on/off switch.

    As the LED is blinking then it shows that all 3 above items are working.

    Yes blinking led is a sign that there is a fault inside with the electronics and we'd need to know the model number to be more precise and what parts to check.

    Although it has to be said that there will be many thousands of volts inside that can cause harm so it is not something to do if you are unsure about doing it.
    Please do not PM me questions that are better asked in the PCB forum :)
