So far everything i have measured on the hot side of power supply is 44 volts. the standby light does not come on and the set doesnt work.

When you make Voltage measurement in the primary side of the circuit, you need to use the negative leg of the main filter cap as the primary circuit GND REF. point for your meter, not the chassis.
So what DCV do you get when you measure between the (+) and (-) legs of those two main filter caps laying on their sides? It should be around 160~170VDC and should jump to >360VDC when the power switch is activated.

OK, the connectors of the power supply board has label for each pin, so report the DCV reading for each pin and WITH pin names so we can see what Voltages we are missing on which pin. http://www.shopjimmy.com/sanyo-1lg4b...pply-unit.htm#

OK. you do habe 160V to to run the standby power supply, but do have any DCV on any of the pin of the connector, it should have at least standby Voltage to run the main board. You need to get the power supply board working first.

You should eliminate the possibility of a shorted main board - check that connector with the main board unplugged, too.
