Theoretical Analysis and Testing: This machine uses a barrel distortion correction circuit board centered around NJO1 (TDA8145). The signal from pin 4 of the XJO1 connector is reshaped and amplified by the internal circuit and output from pin 5. It then undergoes two sets of inductor corrections via LJ06 and outputs a parabolic wave from terminal 3 of the XJ02 connector. Among these, RPJ02 and RPJ03 respectively adjust the line amplitude, pincushion distortion, and raster twist distortion. When adjusting RPJ03 and RPJ02, there was no change in the raster, indicating no parabolic wave output at terminal 3 of XJ02. Upon inspection, it was found that the inductors U04-U06 in the barrel correction circuit had all cracked. Skyworth TV, the screen experiences brief severe distortion.
