PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS X-RADIATION flection. If the shutdown condition disappears, the TV set can be turned-on only if the AC is interrupted for about 20 Seconds and then the on/off switch is activated. To prevent possible exposure to X-Radiation caused by excessive CPT anode voltage, The Digital FCS chassis incorporate a ¨High Voltage Shutdown¨ circuit.
INSTALLER MENU INSTALLER MENU 2-I. AC ON (AC Power Switchable) Use the Installer Menu to set up or change operational settings. See descriptions of the Installer items on the following pages. Allows the TV to turn ON just by applying AC power. Pressing the POWER button is not necessary. This is desirable when the TV is plugged into a cable box or a power outlet controlled by a wall switch. Use ADJUST to select 0 or 1, where 0 is the default is OFF, and 1 is ON.
INSTALLER MENU Note: Clock must be set in order to use Timers. 7-I. START VOLUME This function allows the Installer to determine the initial volume select that volume level when it is turned on. The range of values are 0 - 63, 255. If 255 is selected, the current volume level will be retained in memory when the TV is turned off; at TV turn on, volume level is automatically set to the previous or last level. 17-I.

CIRCUIT OVERVIEW BASIC CIRCUIT THEORY SWITCHED POWER SUPPLY START UP The voltage output of the rectifier BRX3400 (+V1 150VDC) is supplied to the Main Switch Mode Regulator Power Supply (SMPS). The Main SMPS consists of ICX3670, ICX3750, and ICX3751. Its chopper transformer consists of TX3670. POWER SUPPLY DEFINITION The Power Supply uses a COLD chassis and is a single sided circuit board that has been developed for screen sizes 27" through 32".
CIRCUIT OVERVIEW When QX3204 is turned off some of this energy is returned to charge the Scapacitor(s) CX3209, CX3208, and CX3210. After several cycles (repeating at scanning frequency) sufficient voltage appears across the S-capacitor providing an additional path producing current flow though the horizontal deflection yoke coil (connector CN3Y3). The Damper Diodes DX3202 and DX3203 provide the negative current path.
SERVICING PURITY ADJUSTMENT 1. Purity tab positioning. Set the 2 pole purity tabs together in the 3 or 9 o’clock positions and the 4and 6-pole purity tabs together in the 12 or 6 o’clock positions. 2. Move yoke to the maximum forward funnel position. 3. Next, switch the crosshatch generator to a red field. 4. Pull the yoke toward the rear of the CRT neck, keeping it centered, until a red raster is displayed. 5.
SERVICING positions and secure each wedge with a piece of tape, as described above. HORIZONTAL-TILT WEDGE ADJUSTMENT The vertical lines at 3 o’clock and 9 o’clock are converged by horizontally tilting the yoke and inserting a wedge. Adjust first at 4 or 8 o’clock, whichever has the larger space, until the wedge is firmly seated between the CRT glass and yoke coils. Then, insert the 3rd wedge in the remaining horizontal tilt position until it is firmly seated between the CRT glass and yoke coils.
SERVICING is selected as default input.) The rear jack pack includes one set of audio jacks for the S-Video, another set of audio jacks for the Aux. Video input, and a third pair for the RGB Computer input. The Audio processor IC1400 switches between the Sounf IF input on pin 47 (ANA_IN+) from Tuner/IF section and pins 41 & 42 (SC1_IN_L & SC1_IN_R, the L/R channels from the A/V Switch ICM2900). The A/V Switch chooses from among five inputs from external audio sources (Rear and Front jack packs).
SERVICING SIGNALS Three types of signals, ATSC, NTSC and SVGA, are processed in the set. The ATSC signals are down converted to NTSC signals and it are processed as composite video signals. The input pin, of the A/V Switch is the pin 15. •CV RF: The IF section sends the composite video to the ICM2900 A/V switch (CXA2089Q, I2C bus supported) at pin 47. •CV-2: Fed from the rear jack pack to the A/V switch at input pin 8. •CV-4: This input, called Camport, is fed to the A/V switch via pin 23.
SERVICING In the output stage the nominal input signal will be amplified to provide a 4.6V output color signal At maximum contrast and maximum gain settings. Reference or pedestal black levels are adjusted by output clamping (pin 11 HFB). In order to achieve fast rise and fall times of the output signals with minimum crosstalk between Channels, each signal stage has its own supply voltage pin.
