All TV's today have protective circuits, if something isn't right, it will shut down. The power supply is a pulse width modulated type and could be the noise that you are hearing. But most likely the HV diodes have shorted which are molded into the flyback. If you put a scope on the HV transistor case, and see a pulse of at least 50v, the transistor is good, but it should be around 1000v if the HV diodes are good. Put the scope on the highest range, or you will be fixing it next.

The HV transformer is long NLA from the factory & a nte generic will not last more than 24 hours anyway
When I plug in my RCA Projection TV Model P61927 it immediately blows a fuse.

RCA P46729BA big screen, chassis PTK169PCA, serial 337680405. Power supply has died twice & it's out again. Turned it off, won't turn on. Tried other outlets. The guy that fixed before no longer around and no one else will look at it.
