There is a short some where on the power circuit. If I put my mulitmeter on the circuit testing setting, and I touch the positive and ground, it beeps.
I cannot pinpoint the short, so I was wondering if I could remove the whole part.
Are you sure it's in the modulator? If there is a power-ground short, it could be anywhere. I would check the bypass capacitors first on the main board- they can have some longish leads and if one is bent over funny it will short out the rails.
Also, if you see a momentary "short" on the input to the regulator, that'd be normal and is caused by your meter charging up the filter capacitor in the power supply.

As for getting video out of your toploader without benefit of the modulator, it IS possible. You just have to duplicate the circuit that exists in the modulator.
It is a 1 transistor buffer with some resistors and things. I did this mod on my Famicom-copynes conversion to make my Fami's A/V behave like a toaster NES models'. AFAIR the transistor is a PNP model set up in emitter follower mode. Resistor values are the same as the ones used in the modulator.
