You have a very good idea of what is happening,the power supply is likely being pull down by a shorted component,it could be a regulator or the output transistor.The power supply provides about 5 or 6 different voltages to be use for the different circuits,I gave you two ideas but it could be any of them.Be safe and take it in for service.
