Also--if the IR sensor is on a seperate board from the keyboard--unplug it. Then do the same--one at a time--for the keyboard.
FInally..unplug the BL inverter/driver board. There is a CHANCE --it may be corrupting data.
If not luck...likely bad signal board.

Firstly, thanks to everyone for advice and help.
I unplugged the t-con board and still I have no control with the power on/off switch. There isn't any keyboard as the power switch is a joystick like device that has multiple functions. The IR sensor is part of this switch. The driver for the LEDs is part of the power supply.
I am supposed to be getting 3 volts leading to the power switch from the main board though I'm only getting a tenth of a volt.
