M # Z35X21D, rebuilt PWM power supply:
Replaced CX3416 100uf, CX 3413 22uf,
CX3424 2200 uf, both regulators, unit works
fine in every way, but regulator heatsink get very
hot. Touch it for 3-4 seconds...ouch. But the unit
runs all day, just afraid it will overheat & "blow"
again. Did I miss anything to cause overheating?
Horizontal output is cool enough. Rono.

Check the load circuits for those specific regulators, may have something
causing increase current demand.
 
If it's not already home, send it home. They do run very hot.
That's why this repair is rather common.
