I have a Sansui 2000A Stereo Tuner Amplifies that powers up but has no sound. the fuse for the 220-250V 2A was blown and replaced. The speaker fuses look good. Should I replace them too or is there something else that could be causing the speakers to not work?

That series Sansui uses jumpers ( on the rear panel) to connect the pre-amp portion of the receiver to the power amp section.

They are silver colored u-shaped elements . If they are not there , you will NOT have any output.

If you cant find jumpers , use a pair of short RCA ( phono) type cables. red/pre to red/power Blck / pre to Blck power

If the fuse was blown on the 220-250 V side, I am assuming that you are in the UK, if you aren't , but are in the US, change the power setting dial/switch on the back to 100-120v and you might be good to go. Also, I know this may sound silly, but make sure that the speaker selector switch is pressed in or set to a speaker set ( A or B). Love the Sansui gear, have many complete systems myself!

SOURCE: I have an old Sansui 400 receiver. I get no sound

The problem seems to be the left transistor part of the unit. Try this:change A versus B speakers, asuming speaker A was working properly. If still speaker A, now connected to left output does not work, you will probably have transistor malfunction on the left channel of the receiver. Any electronic store will substitute the left transistors.
Good Luck.

SOURCE: Sansui 221 stereo receiver comes

Since this receiver is old-school stereo-only from the pre-subwoofer-era HOW are you driving the sub? Please refer to ITS manual and connect it properly. The speaker outputs for this box are for single speakers only.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Where can i buy a power transformer for Sansui 3900z ?


Let me guess...you took it somewhere for repair, and they told you it had a bad transformer and they couldn't fix it (after they took your money). Sansui began life as a transformer company, and unless something really silly was done (like replacing the stock fuse, which is probably 3 or 4A with a 15A fuse of something). I might mention that 'some' units sold for various locations have a thermal fuse installed internally to the transformer. I dunno if your model has this or not. I mention all of this because often times the phrase 'it has a bad transformer' is lame techspeak for 'I don't wanna fool with this thing'. If it blows the mains fuse on power up, then the most likely fault is that it has blown power transistors at the output of the amplifier. If it 'really' has an open primary winding in the power transformer, then it may well have a thermal fuse that has opened. Gary Brown in Orono, ME has fixed a few transformers for me with this issue. Google can help you find him.

Speakers stopped workin in a 2000 Suburban


If you have a non-original stereo, there may be inline fuses in the wire harness leading to the stereo. Look under the dash with a flashlight and see if you can find the harness. Alternatively, you can pull the stereo from the dash and look at the wires that way.
The speakers can be checked by using a 1.5 volt battery. Unhook the speaker wires from the back of the stereo. Then, using jumper wires, MOMENTARILY connect the battery to each pair of speaker wires. If the speaker is good, you will hear the speaker cone move (it will make kind of a scratching noise) as the battery is connected.
If the speakers check out, and you are SURE that the stereo is receiving power and ground at all the correct points, then I'm afraid that your stereo is likely damaged.

Sansui G-5700 protection light wont go on


Try checking the speakers and connections. Those symptoms occur if there is a short. Disconnect all spkrs, turn it on and if it stays on connect one speaker at a time until it shuts off.

The mini fuse(2A/240v) keeps on blowing up on the power supply port, what could be the problem


You can tell a lot from what the blown fuse looks like. If it's all black or even shattered, it's likely a short circuit somewhere. If it's just blown, then you have an overload.
Another way to find out is by figuring out when the fuse usually blows. If it blows when it's tapped, shaked or moved then you have a loose wire that's touching somewhere it shouldn't.
If it blows when you turn it up high, it might just not be able to handle that much power. Remember to ALWAYS turn down amplifiers when you hear noticeable distortion. Or, the sound pressure from the speaker might be jostling things inside the cabinet.
If it blows when you plug it in/ turn it on/ start using it you've got an electrical problem, not a mechanical one. You'll need to get the multimeter and start tracing faults.

My Toshiba TheaterView has no sound or picture


You may have overloaded your audio output with the external speakers(impedance or short wire problem?)as a result the audio out i.c maybe damaged which in turn may have blown one of several fuses in the power supply.maybe regular GMA type fuse or picofuses,you can try replacing blown fuse but if they blow right back you`ll need the help of a repairman

I have hooked by two bose 161 speakers using 14 gauge speaker wire (about 8 feet) to sony str-dg720. But I get absolutely no sound from the speakers. I have hooked the speakers to port A set of input...


You gots ta isolate the problem.  Disconnect the speakers and hook them up to a stereo you know that works.  If you don't hear sound coming out of the speakers, then you know the speakers are fu.k.d up, so you need to look on the speakers to see if there is a fuse that is blown that needs to be replaced.  If you got sound coming through, then disconnect them and hook them back to the original stereo making sure you got a good connection and all the wires are in good and tight.  Then turn your stereo on and go through the various channels like Tuner, Tape Deck, Aux, and DVD to see if you get any sound.  Also turn the volume knob up. If you don't get any sound after all this, you know there is something wrong with the stereo your using.

Need a fuse for Sansui stereo amp I purchased at a yard sale. Radio shack cares the fuse but doesn't know exactly which one.


Difficult question. Which Sansui amp? You could start small, say 2A, increase by 1's till it doesn't blow or if that is too expensive, 2, 5, 8, 10, 12, 15, get the idea? Just don't start big and expect it to work properly, the fuse that is, it is supposed to blow, not "let the magic smoke out".

Can't find 2A 125v fuse replacement for on-off will 250v be OK?


There is no difference between a 125v and 250v fuse. The most important thing is the 2Amp. This fuse is probably the line fuse and could be the only trouble and may have blow with a line surge. Make sure the 2A you use is a Fast Blow Type. If it does blow again you most likely have a internal power supply failure.

Power Light off & speaker not working


I had the same problem. The screws around the perimeter of the back plate must be unscrewed and the plate must be pried off as it is glued to the box. When replacing my fuse, 2A 5x20 GMA, it blew the fuse again. Disconnecting the second circuit board prevented the next fuse from blowing, but now the question is what is wrong with the circuit board? I cannot see any damage or shorts.
