REQUIRED EQUIPMENTS / CONNECTIONS: RMS Voltmeter: CRT filament terminal. PROCEDURE: 1. Apply crosshatch pattern. 2. The filament voltage must be: TC-20G12P6,15V+0.40Vrms _0.24Vrms TC-29G12P/TC-29G12PU6,3V+0.40Vrms _0.24Vrms
PROCEDURE: 1. Set a music or a external signal. 2. Move the volume control since minimum to maximum and verify if the change is soft. 3. Disconnect the speakers switch and verify if exist still sound on speakers.

AI SOUND VERIFICATION

REQUIRED EQUIPMENTS / CONNECTIONS: RF Generator: Input antenna terminal RMS Voltmeter: TP83 PREPARATION: 1. AI SOUND ON 2. VOLUME MAXIMUN PROCEDURE: 1. Apply standard pattern with 1KHz audio modulated and 25KHz with 100% deviation. 2. Check if the output is : 240 100mVrms.

SUB BRIGHT ADJUSTMENT

PREPARATION: Adjust CONTRAST to maximum and BRIGHT to center. PROCEDURE: 1. Apply standard SUB BRIGHT. 2. Adjust SUB BRIGHT (DAC: B2) to the central part of PART 6 and PART 7 become black. (PART 7=Black and PART 6=lightly illuminated).

PURITY AND CONVERGENCE ADJUSTMENTS
Adjustment is necessary only if the CRT or the deflection yoke is replaced or if the setting was disturbed. 1. When the Yoke or the CRT are substituted: 1.1- Position the deflexion yoke and the convergence ring at the neck of the CRT. 1.2- Position the convergence ring as figure below:
6 pole rings Purity Rings Centered Over G3/G4 Gap
5- DYNAMIC CONVERGENCE ADJUSTMENT
5.1- Move the DY on a horizontal and vertical way simultaneously, to obtain a perfect side colour overcome. 5.2- Adjust the DY position for the image to stay symmetrical in relation to the geometry of the screen. 5.3- Position the rubber parts to keep the DY in place. 5.4- If necessary, use permalloy to correct convergence on the corners. Note: To position the rubber parts (skids) to the DY, keep an angle of 120 degrees between each part as is shown on figure below: 120

Skids (rubber)

4 pole rings
1.3- Turn on the TV set and tune on a red pattern 1.4- Position the deflection coil to obtain an uniform red at the screen. 1.5- Enter service mode and press RECALL at the remote control to begin purity adjustment mode. 1.6- Leave the set heating up for 30 seconds at white screen.
