    Sony KDL55EX500 Main Board Problem

    Hi to all this is my first Post and hoping someone can help

    First off I Run a small Shop, mainly repairing phones and the like but lots of other things as well

    But today someone has bought in the above Board. So got busy looking for the Schematics, Na! could not find them, Sony are no help.

    Anyway, this board has had a fire on it by a Poly Cap (C 6307), taking out C6308 & C6305 and also the Toroidal Inductor at L6301. It does seem to be limited to that though.
    So my Question is, What is the value of the Caps
    The Marking on the Green Caps are: 105J2W R P012 ( The 3 of them are the same )
    and the Toroidal Inductor is so heat affected that there are no indicators on it to give me any clue. Cap C6307 sits basicly hard up against it and it has copped the full force of the fire and heat and as you can imagine all have been so heat affected they can no longer be read with the meter. So if anyone can help me I will be very grateful
    Cheers

    Welcome to Badcaps, What would be helpfull is if you could post good clear pictures of the board, and also the area with the problem, and if there are any other numbers on the board, someone might have a board like it and be able to help.
    Also you should have posted in the "Troubleshooting TVs and Video Sources" forum, you might get a quicker response
    Is this the board?
    The cap.value would be 1uF +/-5% 450 volt I believe those are Metallized Polypropylene Film caps
