Watch for disc caps & box caps off the C of HOT. Common
for them to burn, melt or short. Also burned PCB that
may be hidden under frame plastic. Noise is probably from
SMPS running off freq to keep the overload from wrecking everything.
Assuming HOT is not shorted see if it gets hot in 30 sec.
If so probably bad FBT.
