Sanyo DS27820 squealing!

[Rono]

Checked L413 horizontal width coil, T401
horizontal drive transformer, T601 PWM
trasnformer, & LF601 line filter choke, but
now it's not squealing at all! Anyone see this
happen, & know which part is at fault? Rono.

Get your ESR meter out and check the electrolytics in the smps....
also check the flyback derived B+ sources and loads.
