Yes. Any of those you mentioned.

Repeat tip: NEVER apply unlimited power to a failed SMPS always use a series incandescent light bulb, I recommend 40W in this case, when first testing it out.

You'll probably find the drive transistor shorted, cannot tell from your pic either a shadow or blackened circuit board in that area. May find a protection Zener diode on the secondary side, maybe a shorted diode or two, too. Don't take that as gospel! I said "probably", as in might, may...

And check all capacitors for ESR. Replace those with higher than normal resistance.

my 2¢.
