Your Modal is larger than that, I saw 3 digits are missing.
My model is LE40B650T2W for example.
You can try that tricks at WiKi pages.
I think your firmware could supported too.
You have a LAN jack? If you have, you can use Telnet Enabler application for enable internet.
Also you can check your firmware for enabling Telnet on Firmware.
If you don't have LAN jack on your TV, than you could use ExLink cable to enter your TV's linux console.
This writing is could be good on wiki too.
Thanks

I move this topic to Support area too.
