HI .This is my first post ..thank for your replies and sorry for my english
Maybe I Made a big mistake .

I'm sure that the TV of my grandmother has broken the main board The tv is a le32c530 and the mainboard is BN41-01479A BN94-02699T ,so I order a mainboard on ebay BUT :( :( I thought the same card always went well and still,so so I ordered the same card, but installed on a TV model LE32C450E1W after I installed the board if I 'll try to power on the tv ,the red LED blinks, I can heard the startup sound, but no audio and video I think because the firmware is different ..So is there anything I can do ?? The service menu (info menu mute on) doesn't work

Try to use spotlight and try to get in to service menu. Perhaps mainboard from different model has incorrect type/model. In spotlight you can see shadows of menus and submenus. This means your TV is working, just LCD lights is off.

OR eeprom reset procedure might help either.

Properly made eeprom reset on proper chip leaves no traces. Only if you physicaly damage mainboard (scratches).

I got a great idea .. I am a computer technician and I read that you can upgrade the firmware via ex-link port (service) through rs232 .
I'm able to upgrade firmware via rs232 (it's my job) but you think I can do?
or is it better that returns the card and wait until I find another even if maybe I have to wait so long ??

You can`t upgrade firmware via exlink on your TV.
IMHO Only way to get your TV working - my mentioned methods above. Also no guarrantee it will work.
