Hello.
My problem is that when im turning on my AntMiner S2 its making lots of noice like its working all properly but my Lcs is not working at all. Its like just not working , no leds working no beeping and not even lightening , and of courst showing nothink on it. I hoped its not that bad , that maybe i can just configure it without that lcd working. I followed to steps from other topic : https://bitcointalk.org/index.php?topic=518205.0

"Configuration is straight forward as Antminer S2s are standalone.

Power on as above.
Plug in a network cable from the S2 to your router.
Change your router's subnet to 1, ie 192.168.1.x. This is just temporary. If this is not possible, see below indented steps.
Unplug your computer from all internet sources.
Plug in a network cable from the S2 to your computer.
Navigate to Control Panel -> Network and Sharing Centre -> Change Adapter Settings
Right click on your ethernet adapter -> Properties
Click on "Internet Protocol Version 4" and click properties
Select "Use the following IP address" and enter the following:
IP Address: 192.168.1.1, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.99
Resume normal steps.
Using a browser, navigate to 192.168.1.99 - this goes to the S2's configuration page."

I done all that and still not connection into this configuration page , its not finding anythink.

Do You know what's seams to be a problem?
