Good night dear.

my tv LN37D550 LN37D550K7GXZD complete model, stopped working after have accidentally
selected "MICOM UPGRADE" mode service.
The TV has changed the status of this option to "WAIT" and stayed that way for 10 minutes, without accepting anythig
? command on the remote, I turned off the TV energy
after these events the tv not start anymore, and do not respond to commands from remote control
not respond to keyboard functions and not the totals led standby.

Reading the forum SAMYGO exlink I fabricated the cable and the TV I get the following:

=================================
onboot (Mar 3 2011 - 15:09:38)
release ver : 1003 - RELEASE
etc :
