How could you make it? I guess TV don't let you install B630's firmware...
Anyway. Do you remember that old version of your Firmware?
You needed to build ExLink cable to enter TV and load external firmware from USB.
Just read wiki pages first.
I wish you repair it.

build cable serial to stereo plugs and if you do not have serial port on your PC you need buy USB to serial adapter. you could restore bricked TV if you'll build cable. making exlink cable is easy. after you make such service cable let us know.and we help you further. here is no chance to restore TV without cable. Also possible, that with help of cable we can't. restore TV too. Make exlink and pray to God for Christmas miracle. For cable scheme look at the wiki. How to connect.TV you can find.on.wiki.

You can enable Debug mode using the interrupt button which is placed on the motherboard, it could be like this

Connect it to TV.
Here is the wiki pages has information about process.
http://wiki.samygo.tv/index.php?title=G ... _to_u-boot

In first step, just make a connection to your TV with ExLink. But do not enter u-boot.
If you don't enable Debug mode, than you needed to press panic button (pictures at top. thanks nostromo1983 )
Just capture log and send here. After we recognize the problem, we will say what you needed to do...
