@ian18685 HBC usually stands for High Breaking Capacity or High Breakdown Current. Yours is considered to be "with pigtails" those fuses are not cheap as you can see [https://applianceparts.com/item/6378876/Sony/1-576-233-51/|on here] and on [https://www.tvserviceparts.com/Sony-1-576-233-51.html|as well] Fuses are one of those funny things. Get the wrong one and things can go up in smoke. I am not sure I'd spend 50 bucks on one, but it'll depend on the equipment. I would probably get a fuse like the one you listed and solder some pigtails on it. But that is what I would try, not what you should be doing. Ultimately, the engineers and designers of the projector are a lot smarter than I am, so replace it with the proper fuse.
