Ok...I have and Emerson LC320EMX that won't turn on. When I hit the power button the green light flashes two or three times but then goes back to red. I have tried replacing both the power board, A91F9MPW, and the inverter board, A91F9MIV but nothing changed. The only way to make a difference is to unplug the ribbon cable between the power supply and the inverter. This allows the green light to flash 12-15 times then stay green which I can only assume means it is on...at this state I do have the 170 VDC going to the inverter from the power supply. Does anyone have a service manual on this one or a similar model? I looked at LC320EM9 but mine is a little different.
