    panasonic th42pz80u power supply, plug locations

    Hi, I took out the power supply in my panasonic plasma for repair and when I put it back in, I wasn't sure about the location of two of the electrical connections. When the power supply is in the TV, it's the two connectors right under the fan that have the same number of pins and can be easily reversed if you don't take note while disconnecting them. I'm not sure if I got them reversed or not, can anyone tell me which is the right connection? one of the connectors has less wires in the plug connection than the other so I'm sure it makes a difference if not connected the right way. I can attach a picture of the connections in question if that helps.

    Take a look at the service manual. It may help.

      Those 2 links don't help me, the first one tries to get you to download some advanced version of Adobe PDF Reader and the other one offers to let you download the operators Manual, which I don't need.

        For the first link, go there with your browser software and any ad blocking software disabled. Then wait 60 seconds and eventually a "Get Manual" icon will show up.

          I just removed one of the plugs in question, it is marked "P7" to go into the P7 socket, sort of fool proof. guess I didn't notice it when I originally put the board back in. Anyway I had it in the right spot and not connected the opposite way, which is what I was concerned about.
          Thanks for the help anyway.

            Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
            by sam_sam_sam
            I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

            One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

            Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
            by sam_sam_sam
            I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

            This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

            After all of...

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            by Tynan Dill
            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

            Upon bringing it home and plugging it up, it showed a standby light.

            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

            The screen seems to blackout and stay black, but with a flashlight I can see the display.

            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

            Assuming...

            Modification to a ZD-987 desoldering/soldering station using a external switching power supply
            by sam_sam_sam
            I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

            I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

            Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
            by JimBanville
            The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
            Opened it up and discovered the power supply is making a faint clicking or ticking sound.
            I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
            I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...
