The schematic for the T.VST59.031 series detail several critical subsystems required for universal installation:  Understanding the T

• A chroma bandpass filter centered at the color subcarrier frequency (e.g., 3.579545 MHz for NTSC) is tapped from the IF or composite path.
• Chroma amplifier and limiter (squelch/limiter transistor stages) produce a stable subcarrier for demodulation.
• Color demodulator (quadrature or burst-phase detector) recovers I/Q or U/V components, with matrixing to produce R/G/B outputs or composite color drive lines.

Common faults on the T.VST59.031 often stem from power delivery issues:
