Microphone not working on Sony Vaio VPC-EB2MGX/BI

Specs: Windows 7, Intel Core i5-430 2.27GHz
I have sony vaio VPC-EB2MGX/BI, 8 GB RAM, 320 GB Hard Disk, 2 year old laptop. Microphone used to work fine. One day, I got fed up the noise coming out of my laptop and decided to clean up by opening the back panel. I cleaned it using blower, being careful not to heat enough to break/melt any wire. In the process I think I took the wire coming from the front panel (webcam and stuff) and later reconnected it.
Some day later when I tried to use my mic, it simply won't work. I tried using it on Linux (Arch and Ubuntu), then on Window 7 Professional, Windows 8 Consumer Preview, it just doesn't work on any OS. I guess it is hardware problem. I tried every software thing, new drivers, disabling-enabling my mic on each platform, while my webcam works totally fine. In a nutshell, everything works fine except my mic. Any help will be appreciated. Thanks!

'I cleaned it using blower, being careful not to heat enough to break/melt any wire.'

Why in the world did you use a hair dryer instead of compressed air? Makes no sense to me.....

holy crap...
u might have damaged the board's mic
did u check the volume settings for microphone it might be muted or volume is lowered what about audio drivers are they up to date ?
And the noise coming out of the laptop is probably the fan becoming fast to keep cpu cool bcz its overheating u couldve used a compressed air

computers are a second home

I changed the board mic+webcam. Webcam still works. So, it leaves either wire is damaged or ADC-DAC on motherboard damaged.

I checked the volume on different OSes. No software related bug, I guess.
