Sony receiver keeps blowing 5 amp fuses

It's worth noting here that it's more about the physical size & shape of the Fuse thats needed to fit your Fan.
You don't have to use exactly a 5 amp @ 125v fuse.
Any fuse that Fits and is in the range of 5,6,7,8,10 Amp and even 230v is ok.
The fuse is like a piece of soft metal that will melt if too much current is being drawn by the device. The Amps & Volts only define approximately when the fuse link will melt (blow). But as the fan gets dirty and older the LOAD it draws might get slightly higher. Enough to cause the fuse to slowly melt. So a small to 6, 8, or 10 Amp should work just fine. A wiring short will still cause the 10 Amp fuse to blow thereby keeping things safe. The manufacturer uses a fuse that fits in the space he has allocated & allows the unit to run continuously without blowing on a slight load.
But it is only a safety device to protect the device from internal shorts.
It stops a shorted motor or shorted internal wiring from getting too hot and possibly causing a fire.
But a 20 or 30Amp fuse would still blow if it is shorted.
For example...If the 5 A fuse keeps blowing then you could try say an 8 or 10 Amp fuse. If that blows then their is definitely a problem with the circuit. Don't put anything larger than 10 Amp in.
It then needs to be looked at by a service technician.


The voltage rating on a household fuse isn't that critical.
It's actually the wattage it takes to melt the fuse link. It's based on the mathematics of Ohms Law (Watts =Volts x Amps)
But thats another story....

have you tried a different outlet? something my be wrong internally

No! the fuse you replaced was fine, the power transformer may be shorted, or the audio ouput semiconductors are shorted, check the speaker wires for shorts, if okay! I recommend a pro with a estimate.

Hi,
If the unit keeps blowing the fuse means you have a shored parts on it.
See my tips by clicking http://www.fixya.com/support/r8053361-fuse_keeps_blowing. This is also applicable to your unit. The only thing added to check is the stepdown Transformer for short, also the output IC.
Hope it may help you.
Thanks for using fixya.

usually it is 0.5 amps. if it still blows, you might have a shorted board.

You could have a shorted winding in the power transformer. The diodes in the power supply can be shorted. Filter capacitors can short and send power to ground which will blow the fuse.

I resently hooked up my sony std d 565 reciever for 5.1 speakers and I keep hearing beeping, what is wrong?

if you plugged a 125 volt tv in to a 220 volt outlet you more than likely fried alof of the componets in the tv. Putting a bigger fuse in there is only going to increase the risk of it catching on fire so i would not recomend that. you might replace the power supply and cross your fingers and hope that nothing else cooked when the 220 volts hit it

If you look on the board that the fuse sits on you will see printed it states 6amp 125 Volt / 3amp 250Volt. This means that you can use either one. I think that is why the fuse states E.6.3 125Volt... I think it means either 6 amp (125 Volt) or 3 amp (250 volt). I noticed on the back of a fuse package that I bought that it stated these were interchangable so I put two and two together.

The voltage of the fuse is not the issue. It sounds like you may have some blown internal transistors (probably in the output area). Time for a trip to the repair shop I'm afraid.
