hi ...
I have no electrical engineering knowledge... i have a multimeter but v.little idea how to use it..
so now you know what your up against!
Therapeutic as it is watching the fuse blow i figured it wasn't worth sacrificing a 3rd one to watch it go up in an orange flash.... so i need help understanding the potential root cause(s).
The fuse is located after the power relay and big copper coil thing. Its the next component in the circuit after the big copper coil thing plugs into the circuit board with the two green wires.
In terms of power flow is the issue likely to be upstream of the fuse between the mains power cable connecting to the narrow board with a cap and unidentified resistor/transistor type things) or it could be an issue down stream in the main body of the unit?
I know this is a weak assed description but if you know where to look i can follow instruction well despite my total lack of understanding.

I answered your PM regarding this.

Another BM5500 for the "Workbench" then.....
Yep... Dillen reckons its nearly always caused by the 4700uf 16v cap at c15 so I will swap it out and hope I don't mess it up:) still have to rremove quite a lot of stufff to get to it but seems straightforward enough.
The only thing you will have to remove is the bottom plate.With a little skill, you will be able to desolder the old capacitor without taking the whole moduleout of the Beomaster.
have put it back together... :)
just awaiting part ...
there seemed to be a variety of 16v 4700uf out there from same supplier got panasonic radial eeufk1c472L - hopefully it does te same job only diff i could see was the old one was +85degrees this is 105 degrees. does it make any difference in this case?
