CALLING ALL COMPUTER NERDS: Need help identifying this fuse!

[Caleb]

I need to ID fuse f101, mainly need to know amperage...help!

 

[fullmetaljesus]

Why not tell us what we are looking at, what kind of circuit. What did it come from? What type of board is that, who makes it? when? ETC

Westinghouse LCD tv, what they call a "lips" board(aka, inverter/power board)... When the capacitors blew, it blew the fuse as well.

Got a model number on your tv?

My research says its a Boums fuse, s=2 amps...I need to verify...

I am in sales and work for a distributor that sells fuses, electronics etc. If you can verify I can try to find this for you.

Many times manufacturers will make parts that they sell only to OEM's as proprietary parts. This way you have to pay 100 times the amount you'd have to pay if you could replace it yourself.

Let's hope it's not proprietary.

I'll PM (hopefully I can do that now) with my work email address.

I would have said its a con-fuse because that is what i am.

 

[Caleb]

This might be what I need I think, I picked up a 250v 2amp glass tube fuse to see if the tv will work...if it does, I'll be looking to solder in a proper fuse.

Looks like a standard velocity .22 round would snap right in the fuse holder. That works for automotive fuses.

Ummmmm..... don't really try that

I've seen that YouTube video...I think I'll pass

FIFY

Odd, for 2 amps, it's curious the value(?) printed on the part is 5. That's the trouble with SMC, no room for print anymore. It looks to be a 1206 package, but maybe it's 0805, sort of depends if the capacitor is 0603 (likely) or 0402.

You might find it here.

Want to live and let die? Solder in a piece of wire instead.

 

[Caleb]

Weird part is the screen, backlight, and led indicator does not power up...hooked up a 2 amp fuse but blew it out. Either needs a higher rated fuse or something is shorting out...what could be shorting out?

 

[Mr Evilwrench]

That would just figure, printing "5" on a 2A fuse. Some of these people need to be slapped. Usually you won't have a soldered in fuse blow unless there's something really wrong downstream of it. Replacing the fuse won't fix that. Once you fix that, you can, however, replace it with any other fuse with the same current and speed rating, and equal or higher voltage rating (this is actually important, don't ignore it) as long as it fits physically.

I've done this plus all 8 capacitors...I have a 250v glass tube fuse I'm going to try next.

 

[Caleb]

The 5 amp fuse did the trick!! Not bad for a $5 tv...

 

[PistolBob]

Put an ammeter across it and turn on the TV set, providing you have already repaired the problem that blew it. Then buy a replacement fuse that is rated slightly higher than the ammeter reading.

Or put a 5 Amp fuse in there and see if it blows.

haven't blown yet, so its all good

Common 12V, 5A surface mount that is normally used to protect when mosfets fail (short). At least that is what I used them for back in the day (15 years ago) when I was in engineering.

I'm lucky the capacitors are the only thing that failed, however, I fixed several other tv's and monitors and never had to deal with a fuse before this tv.

Hopefully what I sent you will work long term!
