Hello.
Recently my LG Mini Hifi XA14 stopped working, the problem:
The +5V input (from Power Supply) had burned! So, i clean everything and put two wires (just for test) and with other power supply (ATX) it worked!
So, i check the original power supply, changed one diode and capacitors, and now the voltages are OK
And i tested all again with the original Power Supply and works!
But now i have one doubt, the 2 two components "FB" at the entrance of the + 5V exploded:
So I researched and they would be "Ferrite Bead", in the service
manual (page 38) is the following:
what kind of protection can i put there now? What type and value of ferrite can i use? I only have this kind off ferrites here
