Well, it's on the primary side and it's not the mains filters which are the toroidals on the left. Still cant make any sense of it but then I'm not a designer. Is there continuity between the 3 pins that have the wire wraps on them....have you considered getting the complete board....should be reasonably priced?
SlyAKs:
There is only continuity between the 2 on the same side.. the other side is soldered to a copper strip that wraps around the ferrite (under the blue tape).. only reading 1v when turned on..
Decided to put psu into fridge until REALLY cold and it takes a hell of a lot longer to turn on.. checked for dry joints, fuses etc etc.. running out of options.. Definitely psu but anyone I ask tells me its not this coil in question.. I think it is and until I find a replacement I'll never know.. was looking at a psu for this tv and in used condition they are selling for around £50.. I'm fixing this for someone and the don't want to be spending as much as this on parts alone...
SlyAKs:
Does anybody at all know what the component is? If you where looking for this component, where would you look and what exactly would you be looking for?
downunder:
Indeed we do. Found schematic on net for your p/supply. L504 is merely an inductor. It is used in series with L503, also an inductor,on the dc side of the bridge diode, perhaps because they use only a 100uF main filter - false economy. You could probably bridge out the 2 pins with continuity for test purposes and check if the set starts without tantrums.
No idea where you'd get a replacement (ebay??) but as it is a filter choke only, you may be able to find a coil that does the same job in your box-o-bits.
