Press the "TV/AV" button to stop the vertical scan (Note: the RC/GC/BC is preset to 80, GD/BD to 40) 4. Adjust the SCREEN potentiometer on the line output transformer in such a way the horizontal line is just visible on the screen. 5. Measure the VG2 voltage with a High Voltage Meter and a High Voltage Test stick (1000:1).

TC5.1L CB Circuit Descriptions, Abbreviation List, and IC Data Sheets Vertical Output Section TV Processor This section mainly consists of IC301 (TDA8172), the Vertical Coil and the related circuit. The supply voltage of IC301 are +14V and -14V. These two voltages are provided by the LOT section. For the vertical scan, IC101 creates a Saw-tooth waveform at Pin16. This is the input signal of IC301. The main task of IC101 is to create the vertical scan waveform.
