    Problems with Phillips 42PFL3704D/F7

    So I've had this in my spare bedroom collecting dust. It had an issue with the not powering up. It started turning itself off and that became more frequent to the point where it didn't turn on at all. So I recently found a Power Supply board for it. Installed it and it's doing the same thing it was doing almost a year ago. It will stay on for about 2 - 3 minutes then it will restart. I'm guessing I got a bad power supply since now it comes on but only for a couple minutes.

    I was looking at shopjimmy.com and noticed they do repair work on these boards. I really don't have the patience to change capacitors or resistors. I'm thinking about sending them the original power board and have them fix it. I also got a replacement Power Jack board but that doesn't seem to be the problem either.

    Does any one have experience with Shop Jimmy with fixing boards?

    Thanks

        Well, they said they can't fix it. I don't know why. Maybe it's not a capacitor problem. I've looked all over and no one has them in stock. I found 2 on eBay for around $80 each. If I can get one of you guys to fix it I could pay toy what I would have had to pay Shop Jimmy which is $65. This is what needs repairs.

        The TV Serial number first 3 digits is YA2.

        Here's the problem.

        When I turn the TV on, the TV runs for about 3-4 minutes then it runs through a power cycle and restarts. It does this continuously. Sometimes it will not turn off at all. All of the capacitors on all of the boards look good. Nothing is leaking or blown out.

          Here's another question for you. I ordered a power supply board off eBay. When I received it I noticed that it was missing one of the connectors. The board I needed was aA91H9MIV. The one he sent was a A91H5MIV. He assured me that they are compatible. These are pictures of the differences between my board and the one he sent me.
          The one he sent me doesn't have a CN1804 connector on it. Can I use this board without that connector?

            Is that connector used in the original set? If not and the board looks the same it can't do much harm.
            I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

              There is a harness for that connector on my set. Trying to dig up the service manual to see what that connector does.

              Looks like there are +24 volt and Ground connectors on it. Probably for more devices or whatever included with this TV.

              CN1804 is part of the LCD Module Assembly PH CONNECTOR TOP 10P B10B-PH-KS(LF)(SN). Sounds pretty important...
