    Samsung UE32F5000 (UK model) with no display. Power supply is OK.

    Hi all,

    I have a Samsung UE32F5000 (UK model) with the dreaded standby light blinks 5 times and no display. Using a flashlight I can see a message on screen when I push the menu button, so I guess that means the main board is OK. I've tried replacing the power board but still get the same thing. I presume therefore it must be the inverter, but I can't see how on earth I get to it with this model. The connector from the power board just goes straight into the panel (on the left).

    Any help would be much appreciated. I've attached a photo. I don't have any multimeter, sadly.

    No inverter in this set. It is LED backlit so power supply will generate LED drive current.

    99% sure you'll have an open circuit LED in the LCD panel - a pain to replace as the panel itself has to come apart. Becoming a -very- common issue with Samsung sets.

      Thanks for the fast reply. I was worried you might say something like that! Is it very awkward to fix?

        OK, I've taken the panel apart and can see five Sharp LED strips. Presumably the problem is in one of these?

          You can try testing each with a 3V coin cell (CR2032) battery.

                  Are any of the leds burned? Is it a 5 double blink?

                    Hi guys, sorry to hijack. Having the same problem with my TV of the same model.

                    No picture but sound, can see the imagine in a dark room if you put a torch up to it. I'd previously read that this was like be the inverter but I've opened it up and similar to Sam I can't see an inverter.

                    Completely new to this but it's out of warrenty so I thought I'd have a go at fixing it.

                    Can you please advise me what to check next?

                      Are you sure you are talking about the same model? The Samsung UE32F5000 uses LED for backlights so it does not have INVERTER board which is used for TV that has CCFL TUBES. See post 2.

                        Yup I can confirm that when I opened it up that it had NO obvious inverter board.

                        Model Code on the label is: UE32F5000AKXU and as far as I know it's the UK model.

                          It does not use inverter board because it does not use CCFL, it uses LEDs for backlights.
                          So you should upload pictures for your TV back side that shows all the boards first.
                          P/N of the power supply board BN??-?????

                              Please up load the pictures of YOUR TV, we will need to see the whole backside of the TV that shows ALL the board and then the pictures of each board.

                                  I ask for YOUR pictures because I do not know which board revIsion you have in your TV, same TV model can have more than one version used in the TV.
                                  What are the P/N of YOUR boards?
                                  and 'and then the pictures of each board.'.
                                  So far none of the people here even offer the give out the P/N of the boards after I requested.

                                      So you should upload pictures for your TV back side that shows all the boards first.
                                      P/N of the power supply board BN??-?????
                                      I already said that, again it uses LED backlights so NO INVERTER. How many times do I need to repeat that?

                                      99% sure you'll have an open circuit LED in the LCD panel - a pain to replace as the panel itself has to come apart. Becoming a -very- common issue with Samsung sets.

                                      18 posts and still no pictures of each boards, no P/N of the boards.

                                        Re: Samsung UE32F5000 (UK model) with no display. Power supply is OK.

                                        How can I measure the the LEDs stripe ?

                                          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...

                                          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...

                                          Samsung BN44-00262A H37F1-9SS power supply help finding blown value components!
                                          by cheeky2
                                          This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
                                          I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
                                          Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets...

                                          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...
