Creative SBS 370 2.1 Speaker Problem

[Paswa]

Hey, welcome all friends,,

1 year after buying my Creative SBS 370 2.1 it shows some strange problem. after turning on it, it give crystal clear sound. but after 10-12 second it give a big 'bump' sound and starts humming and the audio output decreased. after 'shaking' the subwoofer box for a few times, it sounds clear again but after 30 seconds the same situation repeat again. Creative serviceman says"It's unrepairable", is it really unrepairable??

I'd be tempted to pull the board out and check each solder joint to see if any are bad. It it works afted you've shaken it, it sounds like this is the most likely problem.

well try to heat the ic by using hair dryer if you see some changeds happen when ic is heated change it some ics do fail after a while of work your problem is really very possible caused by ic fail when its heat increase


i do have question people do any one know what the replacement of yd1006 ic it is 18watt audio amplifier if any one knows please tell me

 

[Paswa]

thanks for your answers. I heated the ic by a hair-dryer, but no
changes happen.

And his question, TDA2030 can be used as a substitite of YD1006

 

[WEALSPEAKER]

FRIEND PAWSA YOU HAVE THEN TO REPLACE THE ELECTROLIC AND CERAMIC CAP NEAR THE IC THIS IS ONLY THING THAT REMAINS ?ALSO YOU HVAE TO HEAT THE IC VERY WELL SO YOU CAN OBSERVE WHAT BAD CHANGES THAT HAPPEN IF NOTHING HAPPEN THEN WAGE YOUR WAR AGAINST CAPS CHANGE THEM ALL ......SO REALLY TDA2030 =YD1006 SO I CAN REPLACE THEM IN YOUR RESPONSIBILITY??

@Paswa

1st of all how is your speaker now?

2nd can you post more photos of SBS 370 opened?

3rd what is the size (inches) of the Woofer used in the Sub-Woofer?

Hey Anybody help to to fix my Speaker problem of SBS 370,which is left speaker output is not working, both speakers is in working good condition . i checked it with plugged in righthand side output. can any body help me to fix this probelm.

Try to change the input signal cable. Second check for any burned or lose solder component.

If this not solve the issue then the IC is gone. Change the IC with new one.

Hi Paswa,

I started searching the forum after my unit experience similar issues e.g powers up but no sound. Did you manage to find a replacement for the IC?

Thanks!

Hi Paswa,
I have a creative SBS 560 and I need to know how you managed to open the woofer.
The back plate comes out by taking out the 4 screws but not completely since 2 wires are still soldered to the woofer also the front frame is covered by cloth beneath which are the 4 screws.Any help is appreciated.

Hi mattcool, as for me, I cut the speaker wire, and I extend or add a wire after assembling it back...

@paswa
change your speaker.

Hi Paswa,

Thanks!

my unit is having problem with the right channel no sounds

I replace an open 4.7K resistor next to a transistor C945... check that resistor..

also I replace (2S)A1015 transistor, problem encountered before replacing this transistor is having no sounds output but have power...

hope this helps....


I have 2 units of this system...

 

[xPeeDz]

also check that both C945, maybe its busted already...

How you managed to remove the front grill from Creative SBS 370 ? I need to open it to check what went wrong with either TDA8510J or Sub-woofer.

 

[xPeeDz]

^^ flat screw.... just like any other speakers grill snap on type... but it's hard to open the grill may damage some wood parts on box but it's OK it's just a minor scratches and deformation.... I think a wide flat scrapper can do the trick to balance the exerted force when opening....

 

[xPeeDz]

An externally hosted image should be here but it was not working when we last tested it.

Mine was replaced with a 1 resistor and transistor in the input channel, 'cause right channel is chirping to no audio output can be heard on that channel..

 

[sameerdhiman]

Thanks xPeeDz

I saw your post today but I disassembled sbs 370 last night. Here are the pictures for others who are still seeking how to open.













Status: Sub-woofer is OK showing 4.2Ohm DC resistance. The BTL portion of TDA8510J is dead, SE portion is still working.

guys.. my sbs 370 is not delivering power in either speakers. LED is not blowing. help me to diagnose the faulty component.
