Blinking codes to many brand TVs are described in detail. http://electronicshelponline.blogspot.com/

Well, unfortunately your TV supports only the NTSC System, while the most of South American states are using the PAL TV System.
Your only chance is to connect a TV tuner supporting both system to make the conversion between the systems.

Green light flashes on and off but wont turn on


That sounds like its not getting any power - enough to start up and then turn off.

Thought 1 is that the control panel power button is busted - the actual piezo switch.

Thought 2 is that there is a short in the unit such that power comes in, turns on the light, but then overloads the board and the thing shuts down.
