Fuse keeps blowing


Once a fuse blows & you replace it-- ONE Time--
then you stop

You go to wiring diagrams of the circuit with the
blown fuse & start your testing

If it blows when turned on a short usually on the secondary side of the power supply---its the part or area where the voltages that are developed are distributed to the rest of the set.

One other odd thing can happen---say a 5 amp fuse is blowing, you go out and buy a generic fuse of same value--at like Radio Shack etc.

Many of the fuses used in modern gear will blow instantly if not the original type and made for that unit.

I had one customer who had a 4 amp blow every time he turned it on--generic fuse-----The correct fuse of same amperage did not do that.

Don't keep feeding it fuses as if a short sooner or later parts that are not now bad will get destroyed and make matters much worse.

TV won't turn on


take the back off the tv and inspect the glass fuse off the ac power cord, it will probably be black and open, this is a common problem, it blows because the degaussing circuit works too slow, the original fuse is an 6.3 amp fuse, you need to replace it with a 6.3 amp slow blow or a 7 or 8 amp fuse to keep it from blowing, if you put an original 6.3 amp fast blow fuse in it, it will work for a while, but will blow again someday.

32'' Panasonic TV, 4 yrs old, keeps blowing the fuse


Hi Mendi.
I had a similar problem, in that I could not find the proper fuse for my set. I bought a bit higher amp fuse from Radio Shack and it ended up blowing a couple months later. I've since pulled the TV down and replaced it with an LCD set, so I've solved my problem.

But, to address yours, I don't think the amp difference would not be the problem. Likely, there is a power issue on your set causing it to draw more amps and become out of specification. Using a higher amp fuse would buy you more 'capacity', but if its blowing those too (repeatedly), its likely a real problem in the set. I'm not a TV technician, so I can't tell you why. I'd suggest taking the thing in for service (cheaper than the house call) or if that is too expensive, looking at putting your money into a set that won't give you those problems. Or, just keep replacing the fuse until it doesn't fix the problem.

Sorry I cant help much more.

The tv keeps blowing fuses


Hi your problem is that a component(s) inside your TV has probably short circuited to Earth, this then causes a massive current to flow and this blows the fuse. Due to the types of Component failure from this, this TV should go to a reputable repair shop. Get a firm "Quote" and an explanation of what needs to be done.
