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

Re: Sound Problem

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.

Re: Sound Problem

"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.

Re: Sound Problem

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.

Re: Sound Problem

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

Re: Sound Problem

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.

Re: Sound Problem

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

My dav-dz270 has no sound from the centre and rear speakers. only the sub-woofer and front speakers produce sound.

Make sure your sound mode is set to Dolby Pro logic II. This will force it to produce sound from all of the speakers.

Hello! Pls, send diagram connector to sub-woofer Samsung HT-DS1000. I want to connect low signal(Sub woofer) direct to amplifier. If connect to AUX - sub woofer sound with delay, no good sound. Thank...

The speaker connections are documented in the manual.

Are we talking about an external add-on sub not supplied with the HT-DS1000? If so, please identify it.

The interconnecting cable itself is a 13-pin DIN.

YAMAHA AV receiver RX-V861 I have the message 'Vol-fix' appearing on Zone 2 and no sound. This was working fine until then

Setting the RX-V861 remote control to operate Zone 2:
  1. Using a ballpoint pen or similar object and press the [CODE SET] button RX-V861 remote control. The[TRANSMIT INDICATOR]on the remote should flash twice.
  2. Using the [NUMERICAL KEY PAD] on the remote and key in 9992, the [TRANSMIT INDICATOR] should flash.
Assigning the receivers internal amp for Zone 2:
  1. Set the remote control selector to [AMP]. (Located to the right of the volume buttons on the Remote.).
  2. Press the [SET MENU]button on the remote control.
  3. Arrow down to Manual Setup and press the Enter button on the remote control.
  4. Arrow to the [SOUND MENU] option and press the [ENTER] button on the remote control.
  5. Arrow to Speaker Set and press the [ENTER] button on the remote control.
  6. Arrow to the EXTRA SP ASSIGN and select ZONE2
  7. Press the [RETURN] button on the remote control to exit out and return to the Manual Setup.
NOTES: There is an option for setting the Maximum Volume and Initial Volume in the Zone Set menu.
  • Max Volume: This is an optional feature but isrecommended to prevent the accidental change in volume levels thatcould damage the speakers and receiver.
  • Initial Volume: This is also a great feature that would seamlessly start the volume level for the second or third zone at the desired level.
We do not recommend using any Speaker Selector boxes to enable more than the recommended number of speakers per terminal.
Controlling Zone 2 using the RX-V861 remote control:
  1. If the Main Zone on the receiver is on, press the [POWER BUTTON]down and while holding that button down press the [PHONO]/[**] button on the remote. The [TRANSMIT INDICATOR] will light up.
  2. You will not be able to use the following buttons on the remote: (Pressing any other button will cause the remote to exit Zone 2 mode. [POWER], [STANDBY], [VOLUME], [MUTE] and the [INPUT SELECTOR] buttons [DVD], [CD], etc.)

There are the instructions as written straight from yamaha. If you need any further assistance please let me know.
Thank you,

I have a LG 42" LCD paired with a LG LHT854 home theater and a directv HD receiver. I the satellite receiver and 854 hooked to the TV via HDMI and the satellitle receiver is connected to the 854 via...

I have an almost exact set-up and you will only get sound out of your rear speakers when the TV channel is broadcasting in 5.1 Ch Stereo. Otherwise the sound is limited to your front, center, and woofer speakers.

I just replaced the cord running from the sub to the dvd player. now my sub will not turn on

steps to trouble shoot for sub-woofer detection :
1. please check whether the cord is securely connected at both the ends.
2. check if there is transmission through the cord (there'll be a small static through the cord if there is transmission.)
3. reset the dvd-player to default audio-output and then choose the 5.1 sound system which is the correct setting for the th-c6.
4. also check the settings in the th-c6 whether it is in 5.1 mode(whether it includes the woofer-as it can also simple use the stereo speakers)
5. now check the sound output in all speakers by playing any original home-theatre system enabled dvd.

the system will work perfectly if the cord is in good condition, otherwise please replace the cord again, and this time check it at the store.
