A common failure with these symptoms in the SD582HD5 is the SMPS module (switch mode power supply). The supply can be removed and what you'll find are ring cracks, together with some possible component failures are causing you the symptoms you're describing.
Reflow solder on all the pin connections and heat sinked components. Test fuses F201 (6.3a) & F202 (5a) for open and replace if necessary. This should restore normal power-up but you may still have a problem with convergence. When the SMPS fails in these units they usually go in a surge. The greatest weakness in these sets is the convergence circuit. And it is possible that the SMPS could cause failure of the convergence amps. If this happens you'll have to replace he amps also. This unit takes two STK392-110's but I recommend you replace them with STK392-150's for greater reliability. However, test the convergence after the SMPS repair and see if it's even necessary.

The fuse alone could not be the problem.. Fuses are symptoms never the cause. More likely you have some ring crack issues on the board and that adds undue electrical and heat stress on that circuit. Eventually, whatever component is involved, will probably fail... You're better off getting the set repaired now before causing some serious damage. Ring cracked components like that can usually be done on an in-home service call... Just my opinion.
