Question about Philips HTS3450 System

1 Answer

I believe the connection to the speakers on the subwoofers are bad. Three work and two don't. Also the fan is not working on the subwoofer.

This most likely would not be a customer repair--please consider having a shop take a look, save some money and possible real trouble in attempting it yourself.

SOURCE: dis-assembling subwoofer

Unless you are good with wiring and can accept having the front cover broken, then you can do it yourself. The speaker protector can be gently pried off but will probably break if not done perfectly. If you get the front cover off, there should be 4 screws holding the speaker. Remove them and then you can see inside. Take note of how the resisters are attached. You may need to solder if they are separated. If you are confident handling this job, go for it, if not, take it to your local repair shop.

SOURCE: Sound from 3 channels only

Hi, first of all did you verify with the manual if it is possible to run a testsignal through all 5 channels?
One of the most common problems in this case is the basic settings of the device. If you don't have the manual, mostly you can download them from manufacturers website. Chances are that for some reason the setting is set 3.0 stereo (also known as 3channel sound) which is always the 2 fronts and the centre speaker.

Best thing to do it is take a DVD with THX on it and run the THX setup, it will send test signal to all channels.

SOURCE: Sound from 3 channels only

Sometimes what happens is that people r just confused with all wirings.Considering that you have connected the speakers correctly...Now according to u the center speaker is not working

  1. If u have a jack attached at the end of the speakers then try connecting the center speaker jack into the Right front/Right Rear/Left Rear socket at the back of the reciever.Just to make sure that your speakers r fine.
  2. Secondly play an audio cd first,sumtimes a video DVD not being 5.1 channel one confuses a lot.
  3. Assuming that you have checked the center speaker,like I asked u too,Connect it into its proper socket or better connect all the speakers.
  4. Now with the remote you check the predefined equalizer in it n keep changing that [pop,rock,jazz etc] or you might even want it to change it to 5.1 from a 3channel or 2channel Stereo.Everytime you change it listen to every speaker.
  5. Also check that you have increased all the speakers volume one-by-one.
  6. Disconnect any headphones attached.
  7. Switch on the selected source or select another source.
For further details u can check the manual.
The VGA cable of the monitor will work fine.

My wharfedale sw150 subwoofer cuts out in normal viewing, any suggestions


If your Wharfedale sub is powered, it gets its input from a subwoofer output on the rear of the Sony. At a certain level, your sub is turned on and sounds just fine until the level decreases during quiet passages of music then it turns off. I believe the theory is that this approach prevents start-up "pops" but in practice it is a poor solution. I have had several subs that have acted this way. I don't know of a way to fix this short of eliminating the level-controlled turn-on circuit

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.


Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

My Mirage S10 subwoofer light comes on showing the subwoofer is on but I cannot get any bass sound to come on. How can this be resolved?


More diagnosis first. We can't assume the source is squawking bass to this thing and you don't mention that you know that to be the case. IS it? The problem could be up the food chain.

We also don't know if you're feeding it Speaker Level or Line Level.

Prove the subwoofer amp is dead or alive by jacking in any source you have that has an RCA output (Tape Out on your unnamed source, CD, TV, etc). Turn the sub volume down to minimum to start as most RCA outputs are at maximum volume. Try that to assess the amp's health. Still dead? Get it worked on.

Ok i just got the sub from a sony sswg450 i want to know is there some way to hook it up to my Pioneer home Receiver


Did you get a manual with it? According to the Sony site this speaker originates in Sony MHC-GX450.

"This product bundle includes the following models:
HCD-GX450 - STEREO MINI SYSTEM
RM-SC3 - REMOTE CONTROL for Shelf Mini Systems
SSRG444 - FRONT SPEAKER FOR MHCGX450
SS-WG450 - SUBWOOFER FOR MHCGX450"


Find the manual here and learn a bit about your seprated sub...

http://esupport.sony.com/US/perl/model-documents.pl?mdl=MHCGX450

See page 7.

As can be seen, the subwoofer has two connections to the mothership, very unlike the standard speaker level (+/-) speaker wire or RCA-Line-Level subwoofer out that 'normal passive or active subwoofers use, respectively.

Not knowing which of those your unspecified Pioneer receiver supports, it is impossible to say. Does your Pioneer have that control jack?

Mini-systems are generally not designed to be pieced out and used with grown-up gear. The absence of standardized connections is the clue.

THERE IS NO SIGNAL COMING FROM THE SUBWOOFER, IT IS CONNECTED TO A SONY AMPLIFIER IN THE SUBWOOFER JACK, AND CONNECTED TO THE SUBWOOFER IN THE LOW LEVEL INPUT. THE SUBWOOFER IS CONNECTED TO THE MAIN, AND...


With everything connected correctly there could be a couple of possible problems:

1. If your receiver has on screen display capabilities, you may need to turn the subwoofer output "on"
2. If your subwoofer has speaker wire inputs/outputs, you could run speaker wire to it, then to your speakers & test if the subwoofer is working... hence verifying that the receiver has a function to turn the subwoofer output on/off
3. The cable between the subwoofer & receiver could be bad. Try another cable.

Good luck!

The subwoofer just quit working the green light is on sound comes out (here voices) the subwoofer no bass


if the light still comes on then the fuse is still good....

a possiblity exists that either the amplifier or the actual speaker itself went bad....if you like you can dissasemble the the subwoofer to access the insides....a simple test....if you connect the driver to another amp (any amp will do as this is just a test) and it makes sound then chances are your amp is bad or just a loose connection.

Subs quit working its not the amp they were working fine


How do you know it's not the amp?  Have you tried hooking up good speakers to the same output terminals of the amp?

Speaker failure modes: Usually they fry, the foam surround disintegrates, or there's a bad internal wire connection/solder joint that fails. Subwoofers are designed to handle a lot of power and rarely fail.

There are three possibilities: 
1) The signal isn't getting to the amp from the crossover.
2) The amp is toast.
3) The speakers are bad. 

You don't tell me whether you have a separate amp for the subs with an external crossover, or whether you have one amp with internal crossover and separate internal amps and speakers outputs for subs and standard speakers, so I can't be more specific.

What you can do is:

Check all external connections, including the power connections.

Try substituting replacements for the patch (signal) cables to see if you have a bad cable.

Beyond this, it's pretty much up to a repair technician.
