This circuit jagged line after line of output from the collector tube VT044 added to the line deflection coil, and the other end by the L422, L441 and S correction capacitors C423, LD02, etc. to form a loop, pincushion correction circuit is added to compensate for the lower LD02.
Now appears a bright vertical line failure, indicating that the former row-level circuit is normal, the fault line output stage. Close inspection showed that the resistance R442 has burned zoom, energized and burn out after replacing the resistor, inductor compensation careful examination revealed the phenomenon of false welding, resistance welding replacement after a good troubleshooting.
Fault Summary: After the line output level due to the current large number of components caused by long working hours after Weld, when there is a vertical bright line should be considered after, after the class Weld phenomenon, focusing on checking the line deflection coil, S correction capacitors, inductors and other landing components.
