My tv keeps blowing fuses.

My tv (phillips crt widescreen) keeps blowing fuses. There must be some reason it keeps doing this, but I can't figure out why. I got it for free from a moving job because it didn't work (blown fuse), and then it worked for about 8 months just fine. Next fuse worked for about two months. And now it works for about five minutes before shutting off. But if I unplug it for a little while and wait, the tv will turn back on and have a picture for about five minutes. Any ideas?

Car charger FUSE melted - WHY ???

Hi ... could someone explain me, why may car charger FUSE has been melted down ??? I was using it several times, and suddenly I realised, that it doesn't work. So I have inspected the fuse, and the wire in the middle was completely melted - a lot of small drops. I have changed the use ... it worked 3 times and again. The next one as well. Unfortunately I can't tell you, if it stops work when the charger is in the socket and I start the engine or by having the engine already running and then trying to put the charger in the socket. I think, I did both of those situations ... but I'm not sure. But WHAT COULD CAUSE THE MELTING of the fuse, when before it was working OK ??? Thank you in advance, Zholy

How do I tell if my multimeter is dead?

I was trying to measure current, then voltage and - basically I had no idea what I was doing and soon everything returned zero. Opened it up, dont see the wire in the fuse anymore. It was rated 250ma 250v 5Ø 20mm. The shop I went to did not have it so I settled for a generic looking fuse rated at 250ma. The multimeter still shows 0 for all the batteries I've tried. Is it time to get a new meter or find a proper fuse?

Help identifying/replacing component

I'm trying to repair an iMac (Flat Panel) that has non-functioning USB ports. I've narrowed it down to this component, but can find no specs on it. I'm assuming it's an temperature/current protection component and appears to be in parallel with unused fuse pads. I'm wondering if I can get away with sticking a 2amp (it drives 3 ports) fuse in there and bypass the component. Any help would be greatly appreciated.

What is a good electric fuse company?

I have been told that different companies make different quality fuses, and that some are better than others. This makes perfect sense to me, but I don't know what companies to avoid and what companies I should go with. I am using these fuses for a Curtis 1243CAN-4276 motor controller (they have a datasheet and manual on their website, the manual has more info), and they ask for one high current and one low current fuse. I don't know the current draw yet, but once I get that value I will put it up here. In the mean time a wide range of fuse choices would be nice. Also a way to hold the fuses and bring them out to two wire ends for soldering is kind of mandatory.

Will a steel wool strain run between a 9 volt battery be able to ignite certain materials?

I am working on using a 9 volt batery if not larger run through wires to aligator clips with steel wool pinched in the clips. I am using it for fireworks. I would like to know if the quick glow of the steel wool would be enough to ignite 2 different materials before it burns out. These materials are 1. Gunpowder Fuse 2. Aerosol hair spray (rather safe then sorry on the potato cannon for test usage)... I am debating wether or not i need that with a primer to make a longer last heat. If so, any suggestions on what kind of primer and how to secure it to the steel wool grain? I have tested the 9 volt running to the steel wool and it does glow and burn itself out but it does not seem to last long or even enough to ignite a paper towel.

what do i need to do to use sparkler fountain black powder in a homemade fuse?

Hi, a fireworks sparkler fountain that i had lying around in my room has dropped its contents as the base clay stuff crumbled away, and what i was left with was a paper case full of fountain powder. the kind of fountain is the kkind that is it a paper tube like normal fireworks, but make a spray of sparks fames and colours of the ground, not a sparkler stick, now sparkler fountain powder isnt like gun powder, this stuff burns slowly, probably because it has less oxidizer. what i need to know, is what i should do to the powder to make it suitable to use as normal black powder when making a fuse using dextrin in the proportions 10/1. i have access to a large amount of potassium nitrate, do i perhaps need to add more of it to the sparkler powder.

Pioneer Stereo Receiver MODEL SX-525 keeps blowing 2amp fuse?

This pioneer receiver has been working for the last 30+ years.  I was using it in my wood shop and went to change the station, I spun the knob to go to a higher station and then the sound cut out and then the receiver turned off.  I then found that it blew the 2 amp fuse (the singled out one of the three used).  I replaced it and turned it on, the lights came on and the speakers put out a law *boooooooo* (low tone) and then the fuse blew again (about 3-5 seconds).   I am not great at diagnosing electrical issues but can replace something if instructed what needs to be replaced.  Please help.             Thank you.

How is a large building wired up? Answered

So, recently, I was at school, and trying to use my laptop charger ( I was the only person in the room to be doing so) However, it didn't work. Using it at home, however, it instantly kicked the RCD or safety switch thing off, switching off everything running off the mains Upon further inspection, I found that the power cable had been damaged, so that the active wire was in contact with the ground wire. My question is, how come the power at school didn't get shut down completely ( the lights were still on, and wall outlets in other rooms around the school still worked) but at home, everything was completely shut down. I thought that there'd be at least a fuse or something, if not a safety switch...

Need advice on making a proposed rocket I've devised different to the ones seen on here, before I waste materials?

I was thinking of making a rocket and using the fuses in a party popper as the propulsion, I was going to set up 4 gutted poppers with just the fuses on a 600ml/1 or 2 lt bottle and use a string fuse attached to the popper fuses at equal distrance running into a centre fuse/string to light it and get clear.I would use skewers or something to make it launch straight up.I would have the bottom of the popper housing/film cannister against the ground/launch pad. Has anyone tried this? Would the popper/poppers just simply blow up the thing I put them in and not work? Would I be better of doing the film cannister cannon thing instead of poppers.?

How can I get my power supply to stop blowing fuses?

I built a power supply using a 25.2 volt 2 amp transformer to use for etching projects.  It worked on my test plate but then started blowing the 1 amp fuses I was using with it.  I switched to 2 amp fuses and it works but my transformer is getting too hot.  I have experimented with different amounts of solvent and different size plates, which definitely makes a difference, though my 1 amp fuses are at most lasting about 10 seconds.  I have read about building a control box with a halogen light and a variable resistor to control the amperage, but would it allow me to take some of the load off of the transformer?  And if it would work, how would I connect it to my power supply?

I need help with short circuit detector / electronic fuse. Answered

So I'm making a variable power supply with an LM317 and I've decided to add a short circuit protection, I know the LM317 has an auto shutdown feature but I thought this would be a nice feature and it would allow me to leanr more about circuits. The short detector is quite simple, It's a PNP transstor connected to the output. When the output is shorted the LM317 can't supply enough current and the load sucks everything it can, so it sucks the charge of the capacitor, causing the PNP transistor to activate and turn on the relay and the LED. This connects the PNP to ground, making it be permanently oopen until the circuit gets reset. It works flawlessly from 16 to ~9 volts, but I go under ~9v (I don't know why) the PNP activates and the relay flickers very fast, I tried several things but none fixed the problem. I have plenty of PNP nad NPN transistors so if you can come with a better and more stable design I would be able to try it, I'll be all the afternoon trying if I can figure this out and posting some updates. Here's a video of how I want it to work. https://www.youtube.com/watch?v=1nVzUUYPm3w& Look at the image for more information. Thanks in advance.

I have a Radio Shack digital multimeter, Model 22-174. Since the 10 Amp measurement circuit is not fused I blew this circuit and that part of the meter does not work now. I like this meter and would like to know if I can DIY repair it and what I need to do. I have looked around the Internet and have not found any information including the Radio Shack site. Was looking for the wiring diagram only found a parts list. I hope that I can fix it. If I can fix it I will fuse the test leads (black lead) or work out an internal fuse for this circuit so I don't repeat my mistake. Any help would be nice. Thank you.

How long can a microwave retain an electric charge when inoperable but still plugged in?

How long can a microwave retain an electric charge?  I think I need to change a fuse as the unit completely stopped working when I reset a fuse for the kitchen when I found our refrigerator had stopped running.  I confirmed that it was indeed the microwave and not the electrical outlet that wasn't working.  This occurred 3 days ago.  The unit is still plugged in - how long would I need to have it unplugged before I could safely remove the back cover to get to the diagram or the main fuse to see if it's burned out?  Thanks for any advice on how to do this, we can't afford to buy a new unit and it sounds like buying a new one would be cheaper (or cost the same!) as hiring a repairman.

It is getting to the secondary transformer fine. Heres a pic of whats goin on. Those things on the sides are fuse holders, (no not burnt out).
