Question about Philips LX3000D System

6 Answers

Sound Problem The problem started approx 2 months ago ,when the sound from all speakers ,including the woofer just didn't come on.Then after waiting between 5 and 10 minutes,there would suddenly be a loud 'crack',and the speakers would start working again. As of yesterday 25/8/06 ,it has remained completely silent. I have tried all the connections ,which seem ok.There is also a very faint background hiss from the small speakers ,which would suggest power is reaching them. Any advice would be greatly appreciated

    I have exactly the same problem. I sent the equipment to repair, but they didn't do anything. Please help!

    No sound. then suddenly a 'bang' and surround sound in all its glory. Except a few months ago. Nothing. Nothing. Nothing.

    Now we still have nothing. Today, I started looking at the internals of the machine. Don't really understand the diagrams enough to really get a clear idea of what's going on. But after cleaning it out with the hoover and poking around a bit - don't know how I haven't fried it with static yet - it seems to have done something, because now again we have (a large number of bangs) but also some sound coming out of the DVD player. Hurray!

    I did press on the sound card also, as someone suggested.

Hi all
I also had this problem. I fixed it by tracing the fault to a dry joint on Z401, a zener diode responsible for the -7v to IC405/6.

There are 4 zener diodes (Z401 - 4) that should have between 6 and 7 v across them. They're visible from the top side of the main PCB.

There's an excellent Service manual available from here.

I'm listening to my LX3000d right now with a smile on my face.

"Could possibly be a bad solder joint that doesn't make contact
until something warms up and expands."
That is TRUE.
I have had the same problem but I do not realy bealive this could be
bad solder joint.
Finally I unscrew many screws and find bad joint
at R467 near zenner dide ZD404 and IC408.
Also check all resistors and zenner diode from +12V and -12V supply
which are under thermal pressure.

Hello people.
First of all, you must be carefull with flatcables and with statics and ressolder all the heatsinks zones, prior to the big one where the output audio amplifier chips are mounted. Ressolder no matter you can´t see anyting wrong.
After it reassemble the pcb mainboard and gently press the pcb over M62446. It´s the volume and tone control. If the sound fails, it must be ressoldered. (SMD, not easy for beginners, and therefore not recommended) or replaced.
Check other components on the enviroment.
Press gently to test.
Ressolder is recommended for all the main board.

Up to today i thought i was the only one that faced this problem but now i see we are many.i am dissapointed that a great and reliable brand like PHILLIPS sells crupy equipment.I thought it was a trustworthy brand but now i will think twice before buying anither PHILLIPS product.I am not a technician to open the product and screw and unscrew.I just wait till the sound appears whenever it does.It's so sad

Hi Larry ,Amazing though it sounds,the problem seemed to resolve itself.Shortly after posting my problem on here ,and after getting no response, I decided to buy another theatre system.Believe it or not, the day I bought it, the Philips unit started working again,and actually better than ever.The only thing I could think may have happened is ,the night before it started working again, I stripped the whole lot down, including taking the lid off the cd player ,and cleaned out all of the dust etc. I also cleaned the cable terminals with WD 40. Whether this was the reason it worked I don't know ,but might be worth a try . Ps Its still going strong, but I've kept the new theatre system,cos I know eventually ,as it is a Philips it WILL GO WRONG.

Hi jabba, Sorry I don't have a solution for you, but I suffer from exactly the same problem. Everything on the system such as DVD playback works, but I have lost all sound. Used to be an intermitent no sound problem, but now getting nothing. Were you ever able to resolve this problem, posted in August as it seems to be identical to my issue? Regards, Larry

Ihave hk395 subwoofer..but i dont have the satellite and a two is possible to use it...if not were i can buy..

U can use the sub-woofer by plugging it separately with a normal 2 stereo speakers.. or ..use 2 speakers attached on it sure they are powerfull enough to make a match ..(usually it is enough 10 watt )
to plug t separately ..just take a look in the speaker configuration option of the driver..and change it in such a way that will allow you multiple out ..(you will see which one will be what ...even on a normal sound card with only 3 plugs ..The configuration you have to choose is probably 3=1 or so ...and will leave your pink for a microphone ..and the line in will turn in a out-let for the woofer ..
Or if the woofer have inlets for the speakers and has a amplifier built in can attach any speakers..
In this case you can use teh normal speaker out ..and get the signal for the other speakers from the woofer ..
In case they were separate ..and the woofer was only connected with the central ..use like I say ..a configuration on the sound manager (speaker configuration ) in such a way that you will be able to connect the speakers in normal green out and use regular 2 stereo ones..and attach the sub-woofer in the plug specified in the diagram ..usually for 3=1 or 4=1 it will change the blue line in into woofer out ..and will work
In this case the speakers used in the green out have to be amplified separately (or have a built in amplifier like computer speakers have ).please ask if you didn't understood the procedure ..and please rate my answer

Establishing computer speakers includes networking to the devices from where media from be derived either as computers stereos of media players. First, the speakers require connection established between each component sound producing device that has an impression in generation capacity. Second, the speaker device have a box usually the woofer as central area with power cuicuit features. Connectable cables are power cuicuit related expected to extend from the woofer to the power outlet. Also, the woofer board would require as last connectivity, the cable attacchment to the devices that produce sound either as stereo music medis players, digital media displayers among mentionable media devices.

My sub woofer stopped working, please tell me where it is located so i can check the speaker and also check if power is going to it thank you very much joe

The JBL premium sound system has a large woofer in the bottom of each door, a small mid-range speaker next to the woofer, & tweeters next to the front door windows in the corner, & two full-range speakers near the rear seats. The woofer (not sub-woofer) handles all the low end. You can test the woofer by turning the BASS to max and TREBLE to minimum (make sure balance and fader are centered) and put your ear next to each woofer.
The woofer is usually the 1st speaker to have problems after 10 years or so. The outer edge of the woofer starts to degrade. You will usually hear a rattling sound out of the woofer when this happens.
NOTE: If no sound at all out of the woofer (tweeters are OK), you might take your car into a car stereo shop. They can put a speaker on the wires connected to the speaker and make sure your problem is not the radio.
PROBLEM: You can still hear sound out of the woofers but it is distorted
SOLUTION 1: Go to a car audio shop and have them install new woofers. These may cost $30+ each but the dealer cost is over $200 for each woofer (crazy).
SOLUTION 2: More involved but very cost effective. If you or a friend is handy, you can go to and order a new set of speaker outer rings (on the site they are called speaker SURROUND) that will replace the damaged outer rings on the woofers (replace on both woofers). They really work great and your speakers should last for many more years.
Hope this helps.

No sound out of 15 speaker and only about half the sound out of horn

1. Confirm the woofer is not blown. Remove it and test it by using an AA battery and wire from the battery to the woofer terminals. When connected, the cone should jump. Alternately, if you have a meter, you can measure impedance. Infinity (or no jump with the battery method) means the coil is open and the speaker needs to be reconed.

2. If the woofer tests good, inspect the connections and wires from the input. Ensure there are no breaks. If the crossover includes a PC board, check for cracks or solder breaks and blown fuses / thermal damage. Repair as necessary.

If the woofer tests good and the wiring and connections are sound, reinstall and test. If there is still no sound from the woofer, test it by conecting it directly to the amp. If there is audio coming through the woofer, the issue lies within the cabinet. Consider replacing all internal cabinet componentry, including inputs. If the input is a 1/4" jack, it is likely thae contacts are bent out, away from the connector. Bend them back to center slightly, and clean them with alcohol or "deoxit".

"Half" the sound from the horn seems normal, as it is not intended to produce bass. If you mean half-volume, that is dependent on settings and measurements and is difficult to diagnose. clmrt5000_1.jpg

Bought a vizio 3 months ago. hate the sound it is very there a solution? have tried all the settins & they don't seem to change that much. Can I add some sort of speakers?

You can try using Powered PC SPEAKERS with SUB-WOOFER. Try using audio line out and set the output to be variable otherwise you will not be able to control the sound level with the remote.
