Randomly replacing components is a ridiculous way of trying to repair
something, have you bothered to do any testing at all? Measured any
voltages? How do you even know the power supply is the problem? It could be
that the microcontroller isn't telling it to turn on. At the very least you
could start with likely parts and not just try to replace everything. Sounds
like you're more likely to turn the cable box into scrap than repair it.
