Deflection
The Horizontal deflection circuit consists of Horizontal Scan, HV generator, and Horizontal drive. Deflection processing is done by U14350 horizontal and vertical processor located on the deflection SIP board. Horizontal and Vertical sync from the I/O board provide sync signals to U14350. A LLC (Line-Locked Clock) circuit consists of a PLL IC (U14351), filter, and external VCO. Horizontal and vertical drives are provided by U14350. The horizontal drive circuit consists of T14300, T14451, Q14451 and their supporting components. The horizontal drive transistor Q14451 drives the yoke and provides sync signal to U14711 horizontal processor. The horizontal processor drives the high voltage generator (Q14700/701) which drives the IHVT (T14700). Horizontal drive and High voltage generation are independent of each other and can operate independent of each other. U24800 (D/A converter) provides control to U14711, focus screen assembly and 1H switching. Vertical signal processing is contained in the Deflection Controller (U14350). U14350 generates the vertical ramp signal with vertical size, vertical DC, S-Correction, and linearity adjustments being made via I2C bus commands. The vertical output is a differential signal that is operated at the same DC bias current with overlaying saw tooth current. Both differential saw tooth waveforms are fed to the vertical output amplifier. The vertical output (U14501) is an integrated circuit containing the power amplifier, the flyback generator, and thermal protection DC coupled to the vertical yoke coils.
