Adjust “Screen VR” until I-H Line appears.Item / Preparation Adjustment Procedure+B Voltage1. Operate the TV set.2. Set control as follows:Brightness.............min imumContrast.................min imumsConfirm the DC voltage at the indicated test points, as follows:TPA 12 : 141.2 ± 0.8VTPA 11 : 8 ± 1VTPA 10 : 5 ± 1VTPA 21 : 215 ± 15VRF AGC1. Receive a colour bar signal at an RF level of 75dBU with 75Ωloaded.2. Connect digital multimeter to RF AGC at Tuner.1. Select “RF AGC” indication in CHK 2, on Screen by remote controlat factory mode.2. Set RF AGC by using remote control volume (+) or volume (-)button until voltage AGC at Tuner reaches 2.7 ± 0.1V.3. Increase RF signal strength by 2dB, confirm AGC at Tuner voltagedrop.High Voltage1. Receive the crosshatch pattern.2. Set to 0 Beam.Screen VR.........minimumContrast..............minim um1. Connect a DC voltage meter to TPA 12 and confirm the +B voltageis 141.2 ± 0.8V.2. Connect a high frequency voltmeter to heater and confirm thatvoltage reads 6.0 ± 0.24 (VRMS).3. Normalize the brightness and contrast.Item / Preparation Adjustment ProcedureConnect a short jumper between TPA 10 and TPA 20.Press Main Menu and Set system to use AV-NTSC (3.58MHz)DYNAMIC.........Normals1. Adjust Sub-Tint so that No. 2, 3 and 4 becomes level waveform issimilar to Fig. 10.2. Confirm phase at Tint is changes more than ± 30 by Tint control.3. Confirm that colour level is maximum when colour DAC is adjustedto maximum position.Note: Use Remote control only when adjusting user mode to Sub-Tint.Fig. 102.6. Pal Colour1. Receive the PAL B/G studio colour bar pattern, and adjust local frequency at the best tuned position.5TC-15PM10R
