Hi and welcome to FixYa,

Initially, pls determine if there are any indications that power is coming into the set such as any of the LEDs is lit. Additionally, pls check if any would be blinking. The sequence and number of blinks would correspond to a general area that the unit has sensed to be faulty. This would then point us to the probable fault and course of action.

Good luck and Thank you for using FixYa. Happy Holidays.

Try first unplugging power cable for ten minutes, and see if the TV restarts.

    IPlug off the TV power cord, also unplug all the TV cables to other devices.

    Wait ten minutes or longer, plug back the TV and restart it.

    If there is no power at all, and no sign of life, test a different AC socket, if still no joy, it is probably a faulty PSU.
    If the power plug is fused (like in UK), check the fuse on power cord.

    If the TV turns itself off completely, with no power and no led light,
    same as if the power cord was unplugged, then this is either a
    defective power cord or power adapter.

    If the TV goes on standby
    state and does not restart, then tv is on protect mode, and this
    happens when a fault is detected. This means that there is a defective
    component that is failing only under determined circumstances.

    the AC networ is unstable, then that can be the cause for the TV goin
    off. In this case you restart the tv by leaving power cord unplugged
    for a while. this can also be tested by a technician.

    Call the technician the same and have the fault fixed, before the problem excalates and you get more damage to the TV set.

    you are in case A, the technican will test power board, and easily spot
    and repair the fault, usually this kind of problem can be caused by a
    defective capacitor on power board.

    If you are in case b, it may
    be more difficult for the repairman to find the fault. This kind of
    faults are often caused by a faulty IC( for example defective
    convergence ICs) or a faulty component on one of the internal boards,
    and it is usually more difficult to locate the problem.

Panasonic TV won't turn on, red led blink

The model indicated was a recalled set--all were supposed to be exchanged under a program Panasonic was forced to use.

The main reason was they were eating lamps up at alarming rates.

I would suggest the lamp (customer replaceable) be removed and inspected---it even if looks good may have to be replaced to see if it is the problem or not.

The lamp issue was caused by a bad Ballast that drives the lamp--kits were eventually made to cure this as the Ballasts were no longer available--rebuilt ones are but not easy to replace.

There is a problem with scan drive 3 boards involved. Best solution and least expensive is call a authorized panasonic service center.
