if the HOT was out and you replaced it with a new one then
you have 2 possible problems.
you have a shorted flyback which is most likely
or one of the low voltage taps have shorted
diodes/caps! but in that case, you normally
get a short attempt to start and shut down.

did you try powering the set up without the HOT in place- if so did the psu
come up ok with hv and low voltage supplied reading ok?

If you haven't already, replace CX3416 (100 uf). The power supply
won't run if it's bad. Here's a nice low tech diagnostic for the SMPS:

When you plug the set in you should hear a soft, sweet little
squeak from the SMPS. If the set is in shutdown, you will hear this
sweet little squeak when you UNPLUG the set.

Occassionally D3410 will be shorted. It will shut down the PS,
but will NOT blow the line fuse. If D3410 is shorted you will hear the
powerdown squeak mentioned previously.
