VPCSB no audio after replacement of keyboard

Hi every one

I got a problem with mine VPCSB
I purchased from internet used VPCSB16FG with arabic keyboard

make long story shor

I repalced Keyboard for UK laylot

after start computer audio driver is there and if you click to small speaker looks audio played but no ouput from speakers

Laptop was opened few times reseated all flat cables and still no analog audio from realtek chip

no speakers no headphones

speaker was measured and they have 8oms

all flat cables measured if pin broken all OK

is interesing - if I connect hdmi digital audio play OK on TV

I find in laptop realtek chip witch is located under palm-rest with cart reader but there in not any number like (swx or cnx)

can you anyone help me with type of board for audio for VPCSB series

I will so appreciate

and if please anyone have repair manual as pdf will be a great.

 

Do you see any audio device in Device Manager?

 

yes audio there as i told no ouput to speaker or headphones

 

I also should check headphones jack because it switches off speakers for headphones and it could be broken too, so there is no sound to headphones or speakers.
P/N for that board is A-1828-964-A and it names V030 MS/SD DAUGHTER BOARD

 

THX

I already exchange this board (btw is IFX-579) and same no sound

I check all flat cables (measured by multimeter) and still not audio output

audio icon there and if you play audio level shows but analogue realtek not send to the speakers and headphones.

I really don't know what can be wrong. I already repaired of 100-ths of VAIO's but this one make me crazy

probably MBX 237 I dont know

 

Hey!
Welcome all here, this is my first post as I am having exactly same problem with my vpcsb! It also drives me mad, tried everything but still no analog sound by realtek! I just wonder did anybody figure it out what's causing this issue?

 

still nope
I saw another vpcsb at ebay with exact same issue.
I decide buy new one with warranty / exchange part by part/ send to sony warranty repair/
if I will something new I will let you know.

edit;
CAN ANYONE HAVE PLEASE BLOCK DIAGRAM OR PDF REPAIR MANUAL

THX MILION TIMES

 

My vaio in first place did not see realtek audio card at all, after messing with the yellow dual layer flex that links daughter board with main one the card appeared in the hardware manager but no sound on the output at all. Forgot to mention, the backlite keyboard is also not working, I wonder is it possible to adress this problem directly to sony? Its just so weird, everything has been replaced apart from motherboard - but mobo shouldnt be an issue as the realtek chip is on the daughter board?

 

try again IFX-579

and check all pins

 

and I have just purchased this off ebay.... doing so diag work now and hopefully can find something.....

 

I have same problem with VPCSE (quite similar to VPCSB)

I did bake motherboard (only motherboard, not daughter board with realtek chip on it). Before baking audio was working fine (but was crashing constantly.) Now laptop work fine except no sound (device is visible in windows and it shows no problem with audio)

 

Hey, I ended up replacing IFX-579 with both flex cables (got new ones from sony), but there is still no sound (sound card visible in hardware manager, icon on place but nothing can be heard) ! Did you find a solution by any chance?

regards,

 

Hey, I managed to replace IFX-579 and both flex cables, now the sound card is visible in hardware manager but there is no sound at all from speakers. Also, the keyboard backlit is not working and card reader, please help me if you know what it can be because Im loosing my head with this laptop!

 

Here is the service repair manual!

You guys might have motherboard issue.
I have answered in detail to another similar post.
Actually, speakers are controlled by chipset. Chipset sends signal to audio chip to enable or disable speakers.
That's the reason why you have almost everything but no sound to speakers.

 

Hello.
I have the same problem in VPSCB, someone could fix?
I have HDMI sound, but nothing on speakers and headphones.
I have the original drivers, the problem is in the motherboard.
Thanks.

hi guys. I have exactly the same problem with ... Coca Cola hit the keyboard, disassembled, cleaned, assembled, there is no sound ..... In Device Manager, the sound card is present. The indicator shows that the sound plays. But not in the speakers not the headphones are inserted into the slot there is no sound.
Do not know what to do. Did someone solve it?
