Title: Samsung BN44-00260C PSU & Inverter Combined Schematic?
Post by: cheeky2 on October 30, 2015,05:33:32
The 32inch Samsung PSU blows the fuse so need the schematic for the PSU. I have the  BN44-00260A version but this version is different to the C version.
Thanks Anthony

Hi Cheeky,

Not clear which one you're after. Here's the A version. If you need C, I may be able to acquire it with the Model #.

Thanks i have the A version but i was after the C version of it.

 Fortunately for me i put a lower rate of fuse into it T3.16A and it blew! However i noticed afterwards that the LX802S ferrite coil and two windings had vaporised in a couple of places! It looks like that the ferrite core had cracked and the coil winding had vaporised in the area of the crack! Resulting in the arcing and blowing the fuse! See picture attached for location of coil

 The coils both tested good i guess the windings might have shorted out with each other. Most unusual as this has never happened to me before! I see that they do a kit for repairing it and all the mosfets and bridge rectifier were tested good which totally confused me.
 Instead of putting a lower fuse i would have normally put a bulb in place to check it out to identify the offending item! I have now used a ferrite coil and windings from an old ATX psu i use for spare parts. Just testing it now for durability and looks all good so far. Also ordered the correct T4A fuse for it as well :)

 Happy Days :)
