    O.k this is a projection tv.

    Did it make any particular sound or the picture acting up before it shutdown?

  • truecut06 May 14, 2010

    no it worked one day and the next day nothing. I have no control at the buttons, when I plug it in it sounds like it is turning on, but no picture, it makes some quite electronic sounds like it is trying to do something but again nothing happens

    The most standard problem with your model is the convergence circuit.

    That is what aligns the colors blue /green/red so they make one.

    The first thing the touch focus will do is activate that circuit to verify and correct any mis-alignment.

    So in case of a weakened convergence circuit: it may precipitate any fault that would have occurred anyway.

    That would be my first diagnostic.

    If you`ll give me a few hours, i`ll see if i can pull out a service manual and give you more detail info.

    I`m sorry

    Disregard the last comments , they are not directed at you.

    I`ll be right back

    O.k except for the fact that the most often seen problem with your set is the convergence circuit.

    We are not there yet.

    But i`d still ask you if you can give me a few hours so i`ll look for the service manual.

    That way i could give you more detailed info.

  • truecut06 May 14, 2010

    any other ideas?

    Hi again

    I`m still waiting on a friend to send me a service manual.

    In the mean time perhaps if you open the back and follow the power cord , it will bring you to the power supply.

    You should find some fuses, it would be a good idea to check them and look around for components that may look burned.

  • truecut06 May 17, 2010

    Hey, The fuse looks good and nothing looks burnt.

  • truecut06 May 17, 2010

    I only found one fuse? Does that sound right?

  • Jacques Marin
    Jacques Marin May 17, 2010

    I`d like to send you a service manual, it is too large to be uploaded here so i would need an email address.

    It is not the exact number but it should be very close: yours is the wx54 and this one is wx53 so they probably have the same chassis.

    That would help to continue.

  • truecut06 May 18, 2010

    My email is

  • truecut06 May 18, 2010

    I just wanted to make sure we have the same modle # mine is a Panasonic pt47x54j

  • Jacques Marin
    Jacques Marin May 18, 2010

    As i said this one is the pt47wx53 instead of wx54 but the changes might be minor and the chassis still the same.

    Once you have it , i`d like you to look at pages 16 and 17 and tell me if it looks like your tv.

Push statrer button and nothing happens

Sounds like too much oil! Yeah it sounds like a switch. You can probably get that thing apart and see what's happening. Have you ridden in the rain lately or trailered it through heave rain? I trailered my Ducati through some heavy rain in North Carolina and washed all the grease out of the throttle, wouldn't even turn. I have a feeling, you have corroded the connection some how, check it out.
