ive been reading these posts after my local repair shop wasnt interested in repairing (or even looking at) my Philips TSU6000 remote/charger.
having read here, i now know exactly what the fault is. The Fuse.
In my case its completely fried :(
I like your idea of having the fuse located externally and i would be very grateful if you could post (or email me) some pics of what fuse you used and holder (if any).
