    Philips 42PFL7403D/10 circuit diagram not found

    I got this TV. the former owner gave up fixing. Problem is that now all electrolytic caps have been removed from the Power supply board.
    The service manuals I found on the web do not cover my power brd.
    The chassis is a Q529_1E_LA
    The power board has the following I'd:
    JC 837.6 D03.D. 0059164
    2722 171 00595 REV:03 F

    Hope someone send clues

    272217100577 (42pfl7603d) should be the same as your IP ( inverter & power supply) board. Check if it is DPS279BPB and has a "v" (Green or blue colour mark) in front of DPS279BPB
    I can get you the power board should you need to.
    good luck

      Sorry Ikbits I forgot to mention. I ve worked for Philips and There are not diagrams for this psu/ IP board as far as I am aware of. Those boards are not made by Philips and and they never released any circuit diagram.

        Thanks Arfi, meanwhile I got this link and have the schematic:


        it is a Delta powersupply and you can download from
        http://elektrotanya.com/power-invert.../download.html
        Attention! you can download 2 schematics free a day you must wait!! until
        This file is downloadable free of charge: Get Manual appears!!


        IT is not Philips indeed! But anyway the cap's are repositioned and the set turns on!
        BUT... now the picture is somehow sort of negative and blurred....
        So the search continues,

        Make it a good day!

          Hi,
          I'm Paolo from Italy.
          I have one of thes PSU in my workshop,but I think You don't need my help anymore .
          By the way,let me suggest you something about the other picture problem.
          Check and change the small IC named AS15 in the T-Con Board.
