Would it work to use one of these or would it impede the normal power supply since I'm only feeding it 110V? The original fuse is 125V rated of course. 250V rated fuse if plugged on 240V will guarantee you fry things deeper inside. Stick to the original rating, not a good time to be creative in electronics design power protection! Julien

I'll order a new fuse.
I'm my own worst enemy. Anyone here revived their LD player after doing something similarly dumb? If the design was well made, the fuse took the hit and the power adaptation was spared. If you are less lucky, the power adaptation level got hit but didn't damage anything further and the module only needs to be replaced. Maybe the player had multiple worldwide releases at different input voltages, that would require a modular design. If the design expected a perfect power feed with no extra margin, it's up to the original designers... Julien

Thanks Xtempo.

My fuses arrived this week and I got some time today. Now for a guy who looks at electronics wrong and they break replacing a fuse isn't as easy as it sounds. First I didn't want to remove anything except the top/side panel and that left a tiny gap to try and position the fuse into the housing with tweezers. Tried this for an hour unsuccessfully before giving into the fact I may have to lift a circuit board and manually move the tray (something that has every time resulted in me messing up the complex Sony tray and door mechanisms on other players). Then I looked at the back panel. Lots of screws, are those inputs and outputs attached to it I thought..? Hmmm, removed all the screws and it came away clean, giving me clear access! Put in a new fuse and the rear panel back on. Plugged the power in..good as new! Looks like the old fuse did its job and protected the player. Phew, that was a close one, almost lost my only dual sided player and losing any otherwise reliable player at this point is bad news. Very happy. Think I'll celebrate tonight with something with a lot of sides, probably Gojira vs King Ghidorah (Heisei version) in CAV.
