Emerson 32" HD Digital TV LC320EM8AN may be the same TV.
Fixya: Generic problem for all Flat Panel Televisions Stays in standbye and will only flash green (power on) twice before staying in standbye
This TV powers on then switches back to off standby within 1 second. All capacitors look good. On the inverter board I see a wire chart for the interface to the video board.

6:B/L - ON
7:B/L - PWM
8:GND
I unplug this inverter to video board cable and now the TV led flashes for several seconds then stays on which is what it did when it worked. Of course there's no picture. All that protection must be the inverter detecting a fault and telling the video board to shut off. The inverter board is cheap enough but not available and I need to ensure the lamps work.
I test the 6 inverter channels and the 6 lamps. All lamps work. Inverter channels 1 and 3 are dead. Transformer 3PC0XB001 is not available but crosses to LTZ2PC0MS008 which is available everywhere including Sears Parts Direct at a price so low I order all 6.
Transformers labeled V2L Q94111 or Q94III arrive. They are slimmer than the original part. It seem unlikely there could be two bad transformers. The TV prevents operation with the first failure so a second failure should not occur. I change the Channel 1 transformer first and now the TV works.
