ATC113 ALIGNMENT PROCEDURES Operating Conditions Unless otherwise noted, the following conditions must be observed when aligning the ATC113 chassis: 1. Chassis must be operated from a 120VAC isolation transformer, with line voltage set to 120VAC (±2.0V). 2. Picture controls (brightness, contrast, etc.) must be set to factory presets via the Picture Quality menu presets item or reset on the remote transmitter. 3. Procedures must be performed in the sequence given. 4. A 10X probe must be used for oscilloscope and frequency measurements. 5. Minimum warm-up time is 10 minutes Personal Computer: IBM or Compatible 486DX 66 meg PC (or LAPTOP) with 16 MEG Memory, VGA Monitor, one 3 1/2 floppy drive, 540 Meg or larger hard drive, compatible mouse, one parallel port dedicated for service interface box and one port for mouse, Windows 95, 4X CD ROM, Printer and Sound Card. Isolation Transformer: Digital Voltmeter: Range .1V DC to 1000V DC, Accuracy: ± .5%/ True RMS Voltmeter: Range: 01 to 1000 Volts ± .5% Accuracy DC Voltage Supply: Range: 0 to 50V, 2AWell Filtered Temperature Controlled Soldering Station: Grounded Tip TypeTip Temperature 500F to 800F Adjustable Frequency Counter: Range: 50Hz to 100 MHz Sensitivity: 25mV to 5V. Equipped with Lo-Cap Probe (10:1 Attenuation) AC Variac: Continuously Variable. Isolation Type Preferred NTSC Video Signal Generator: Must provide 1V P-P Negative Sync, Video into 75-OHM input. Produce, standard NTSC 75% Saturated Color Bars with 100% White Window. (B&K 1249, or equivalent) RF Signal Generator: 100 kHz to 150 MHz .1V RMS, Int. Mod. 1KHz 30% TAG001 Tuner Alignment Generator (stock # 215568) or equivalent: Equivalent Generator must have RF output capabilities for cable channels 1-125. Cross Hatch Generator: Must have RF output. S-Video Source: Must provide standard Y-C separated signal. SVHS output of VCR, DSS or DVD will suffice Dual Trace, Delayed Sweep Oscilloscope: 25 MHz with Channel invert capability. Sensitivity 5mV/cm Maximum Sweep Rate: .1us/cm. Hot Air Desoldering Station: MTS TV Stereo Generator: Must produce L-R, L+R, SAP at 300 Hz, 1KHz, 8KHz(B&K 2009, or equivalent). Chipper Check® software: Chipper Check® interface box NOTE: All alignments with the exception of basic color temperature and geometry require the use of Chipper Check® software and interface box. Service Mode ATC113 ALIGNMENT PROCEDURES Most of the alignments for this chassis are software-driven. Adjustments are made by modifying parameter values using Chipper Check and the service menu. When parameter values are modified, the corresponding T-chip registers, tuner registers and EEPROM locations are updated. A list of the software alignment parameters accessible using the front panel is shown in Table 1. All other alignments require Chipper Check® Using the Front Panel Controls to enter Service Mode 1. 2. 3. Turn the instrument on. Press and hold the MENU button. a. Press and release the POWER button. b. Press and release the VOL+ button. Re
