    panasonic led 32- no standby power no led?

    hi i have a panasonic led 32 tx-32c300e that has no sign of life no power and no standby led,

    it has the following power supply board tnpa5364 ad 3p

    i am guessing that the power supply is broken but i need help with diagnosis.

    at TP7502 i have 0 v should be 5.7v

    On some Panasonics they do not turn on the STBY LED when the TV is off. So the TV is off, the LED on front is off also.

    Based on what you are describing, either you have no STBY voltage on the power supply, or the main board isn't telling the power supply to turn on.

          This is a Vestel set ? Upload some images of the boards please.

              Its a set not built by Panasonic and uses Vestel boards/chassis. You confused me as the model of your Tv is built by Vestel according to google but you say it has a Panasonic Psu ??? Got images of the board ?

                Vestel = Totally shitty Turkish maker of TV Garbage popular for the big names to re-badge in Europe....

                Seeing it has a 'TNPA' part-number, I'm guessing genuine Pan.

                        Sorry to disagree, but there's loads of engineers that also think Vestel = utter Crap--whether they have patents on their turds is meaningless!!

                        You can patent practically anything, just makes it harder for other Co's to copy--But Who in their right minds would copy a turd!!

                                          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...

                                          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...

                                          Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock

                                          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...

                                          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...

                                          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...
