Why does the fuse blow Instantly?

I recently got this VSX-305 receiver from a friend we tested it(extensively) at his house and it worked fine. I brought it home hooked it up to a sub and my pc. While using the 8 ohm sub the 6.3 watt fuse blew and the receiver wouldn't power on. I replaced the fuse with a 6 watt one and as soon as I plugged it in It blew Instantly not even a second between me plugging it in and the replacement fuse blowing. I again replaced the fuse, and tried to do the same on a different outlet but it blew again. Is the .3 watt that much of a difference or is something Internally damaged. If so what could It be and how can I fix it.

Link for the service manual: http://elektrotanya.com/pioneer_vsx-305_405.pdf/download.html On page 50 of the manual (36 of the pdf) it says for the "Sub woofer pre-out jack (Not available on the VSX-305 model) If you want to boost the low frequencies, connect to a subwoofer power amplifier" Your model will not drive a sub-woofer with out another amp. His sub may be a powered sub?

You need the remote...or a universal remote you can program to the VSX-305 to un-mute it.

If it's under warranty..get a new one.
It's an internal breakdown ...tech service only.

SOURCE: Pioneer VSX-D608 Optical connection

The manual states that the default association of each digital input in as follows:

  • Optical 1: CD
  • Optical 2: MD
  • Optical 3: TV
  • Coax: DVD
Use the "Signal select" button to set the receiver to use a digital input, and the Dolby/DTS button (above "Signal select") to enable decoding.

As samz11 stated above, a remote is required to alter the digital input mapping.

SOURCE: Pioneer VSX-D412 AMP-ERR message.

Hello,
The AMP-ERR message in many Pioneer Receivers is caused by some DC in the output. The microprocessor then issues the warning and shuts the unit off. It is definitely not a relay switch. It could be the amplifier power pack, i.e. PAC011A or similar that is faulty or something else. Not easy to repair for the non- experienced DIY.

Good luck

SOURCE: no power

Press TUNE+ & AUTO SURR/DIRECT keys continuously for 2 sec. and it will tell you the fault it encountered if the receiver is in otherwise working condition.

Hello - Our Pioneer vsx-305 display screen doesn't light up anymore and we are unable to get it to work even though the on/off button appears to operating correctly (red standby light comes on). T

It is likely failing due to age.Cold solders fail, corrosion can cut a connection, a capacitor can harden and fail... a myriad of things can happen in time. Repairing it will cost more than an inexpensive replacement. The same receiver can be had on ebay from $60 up (with shipping). It is a cost benefit issue at this point.

I had a bad speaker wire on my Pioneer vsx-305 and the 125v 6.3a fuse blew. Where could I find a replacement fuse?

You can get fuses from any electronic parts shop, such as Maplin (UK) or Radio Shack (USA). I would get a few, because chances are the fuse did not just blow because of a bad speaker wire! Fuses are there to protect the device from an overload (which would cause a fire). The mostly likely cause of your fuse blowing is that your wire shorted out an output transistor on the channel the speaker was connected to and the transistor is acting like a piece of wire now!
If you have an Ohm meter I would put it's probes on the terminals of the transistors on the heat sink. You will soon know, as it will be just like you have touched the meter's probes together!

The stand-by light is supposed to go off when you power on the receiver. You should get the display light and you should have power on.

Universal home theater remote for Pioneer VSX-305 audio/video stereo receiver

Don't spend a lot of money for a universal remote. Radio Shack has some good buys. I think you are the same person who is having problems with a 305. Get rid of it. You can make a quantum leap at Amazon for less than $200 for a Pioneer.
