    Re: Samsung SyncMaster 943BM - backlight only for half a second

    It occurs to me the display is very similar to a 932B I've been repairing few months ago, it uses the TM-0917 transformer. Looky


    Main differece is the SMD button board is connected to connector on signal board, not on the power board but the primary/secondary is basicaly same and the inverter looks almost the same.

        Did you check the resistance on secondary side of that transformer? Quite often a bad transformer can cause immediate lamp inverter shutdown...

            what is that washer on there?
            Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

            You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

            Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

                Cooling? There should be a strip of metal soldered in from the factory, they did not do it and you can see how darkened it is…so I've added it

                lexwalker: what do you mean?

                    Samsung Syncmaster 740BF repair
                    by soopacrucial
                    Hi folks,

                    I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:

                    Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of.
