Question about Draper Cineperm 132" 1.85:1 Projector Screen
I had the same problem. Took the back off and found the 6.3 amp fuse blown. Replaced it with a 6.3 amp 250V fuse and cleaned out the dust especially off the high voltage transformer. It seems to be working ok now.

It sounds as if you have a component that has changed value enough in value to cause a high current draw, but has not completely shorted out. this phrase from you "so I did a stupid thing and bypassed the internal fuse and it turned on and worked" Not as stupid as you would think because it confirms what I said above, the 6.3 amp fuse tells me that the current draw normally is about 3 amperes since the normal rule of thumb is to double the value of the current to select the type of fuse. a five amp fuse should as well as a 4 amp fuse (it's best and recommended to use the exact fuse type). Now back to your issue. I would suspect that a transformer in the power chain has developed a shorted winding, or a capacitor begun to develop a short or excessive absorption.
I would suggest that you have the set looked at by a qualified TV technician.
I hope this helps,
