Sanyo DS27820 squealing!
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. electricitym - - - - |
