ALIGNMENT PROCEDURES
Operating Conditions Unless otherwise noted, the following conditions must be observed when aligning the ITC222 chassis: Chassis must be operated from a 120VAC isolation transformer, with line voltage set to 120VAC (±2.0V). Picture controls (black level, contrast, etc.) must be set to factory presets via the Picture Quality menu. Procedures must be performed in the sequence given. A 10X probe must be used for oscilloscope and frequency measurements. The audio output leads must not be shorted together or to ground with the chassis on. All video signals must have -40 IRE sync tips unless specified otherwise. Chassis AC power must be removed for 10 seconds before disconnecting any cable. A 3-minute warm-up is required for chassis or module related alignments. A 15-minute warm-up is required for Kine or Convergence related alignments. Required Test Equipment - Dual-Trace Oscilloscope - Digital Voltmeter - Frequency Counter - Audio Signal Generator - NTSC Signal Generator (B&K 1249, or equivalent) - MTS Signal Generator (B&K 2009, or equivalent) - Sweep/Marker Generator (or Standard Signal Generator) - YPrPb Signal Generator (DVD player w/YPrPb) - DC Power Supply (5.0V/0.25A) for TAG001 - Chipper Check ® software - Chipper Check ® interface box and computer - Personal Computer (IBM Compatible w/ CD ROM and Sound Card) NOTE: For optimum performance it is critical that this instrument be properly aligned. For Auto Convergence to work correctly it is HIGHLY RCOMMENDED that the geometry alignments are first verified Small Signal Board (SSB) Replacement All alignment data is stored in EEPROMs located on the Small Signal Board (SSB). If the SSB needs to be replaced, it is HIGHLY RECOMMENDED the EEPROM data be downloaded by using Chipper Check. Once the SSB has been replaced, upload the alignment data back into the instrument. Then verify that the instrument is properly aligned. 1. Open Chipper Check. Select "Dead Set" "ITC222". Follow the On Screen Instructions to establish a connection. Fill in the Customer Information on the "Customer Info" tab and change to the EEPROM tab. The following menu should appear.

3. Follow the instructions on this screen to copy the alignment data from the defective SSB to the new SSB. NOTE: It may be necessary to perform the geometry alignment to get the auto convergence to work correctly. Please refer to the section on Geometry Alignments CRT Replacement (PTV Models) If only 1 or 2 CRT's are replaced use a convergence pattern to align the new CRT. Align the new CRT to the pattern generated by the existing CRT. Then run Auto Convergence. If all 3 CRT's are replaced, it will be necessary to first center the Green CRT using a pattern with a center dot. Then align Red and Blue following the Geometry Alignment procedures in the service data. Service Mode Most of the alignments for this chassis are software-driven.

sembled and placed back in the mounting as close as possible to the original CRT and yoke. At this point having the convergence pattern on screen will assist in the mechanical mounting. Using the centering rings and observing the convergence pattern, rotate and move the pattern until the replacement color overlays as close as possible to the two colors not replaced. Moving the ring tabs together around the neck of the CRT draws the raster in small circles. Spreading the tabs apart moves the raster in more linear angles. The closer the tabs are together, the less affect on the CRT beam they have. When the raster is as close as possible fix the magnets with paint or nail polish to prevent further movement. After fixing the magnets, if gross geometry errors are apparent, geometry alignment is indicated. If the raster is close, use the "Auto-convergence" feature provided in the consumer menu to re-align convergence. This should correct most minor geometry problems. Follow auto-convergence with the consumer red and blue centering adjustments, then evaluate the raster again. In most cases convergence will now be acceptable. If only slight convergence errors are noted the technician should enter the manual digital convergence menu and begin "touchup" of the screen. If gross geometry errors are still apparent re-evaluate whether the errors are noticable on the replacement CRT or whether they are global, affecting all three CRT's. If the errors affect all three CRT's a full geometry alignment is indicated. If the errors only affect one CRT, particulary the replacement, return to the mechanical placement and centering ring adjustments and begin those procedures again.

IRE bar location. It is the "black" or "cutoff" bar. For these adjustments this bar and the next brighter bar will be used. On most patterns the remainder of the bars will progressively become brighter. Adjust Black Cutoff R or Black Cutoff G until any tinting disappears from the black bar. When properly adjusted the adjacent bar should be a very low level gray with no color tinting. Now observe the brighter portions of the bars. Adjust Whitpoint R, G, or B to remove any signs of tint in the higher brightness bars. Observe the bars for signs of CRT overdrive. Some compromise may be required, but the higher IRE bars should be as free from color tinting as possible. There are separate color temperature alignments for RF (NTSC), Comp 1H, Comp 2H, DVI and AUX_RGB (If unit has DVD option installed). 2. 3. Adjust for peak white. Contrast Max and Scaling Contrast are preset according to the CRT type selected and do not need to be adjusted.

Note: bel ow . The purpose of the color temperature setup is to assure uniform gray level from black to the brightest scenes. If a uniform gray screen is displayed, no matter the brightness level, no tinting in either red, green or blue direction should be apparent. This is known as "color tracking". Once the proper color temperature is set, AKB will maintain the cutoff of the CRT to assure proper low light performance. Black Cutoff R/G, Whitepoint R/G/B Setup (Recommended Method) 1. Apply a gray test pattern giving a 12 IRE flat window. Connect Colorimeter near the center of the screen. 2. Adjust Black Offset R and Black Offset G to obtain the following color coordinates. Direct View Projection TV X 0.282 0.283 Y 0.298 0.296 3. Apply a gray test pattern giving a 50 IRE flat window. 4. Adjust Whitepoint R, G, and B for the following color coordinates.

The last five event codes will be displayed, along with a time stamp from the run time counter. The time stamp will display the last occurrence of a particular event. The time stamp is displayed as "Run Hours". An event counter counts how many times that event has occurred. The counter will not count beyond 255. The most recent event code is displayed on top. To clear the event codes from memory, select the Clear Event Codes box. A long press will clear all stored codes. Only the last error code stored in the NVM can be read with this method. The LED will blink two separate digits. Example, if the error code of 23 is the last error code stored
Note:
This alignment must be performed in each of the following modes, Tuner, Comp 1H, Comp 2H, DVI and AUX_RGB (if DVD option is installed).
16. The Drive Level Alignment is preset according to the CRT type selected and does not need to be adjusted. 17. Before exiting the Video Alignment Submenu, check Store to save all alignments. Color Temperature Color Temperature for the ITC222 is similar to past chassis. Some form of staircase pattern similar to the figure below is required. Proper identification of the "0" (if available) and "7.5" or "setup" bars on screen and the waveform produced on the cathodes of the CRT will be needed. Consult the specifications manual for the pattern generator used to confirm the location of these bars. The oscilloscope waveform shows the relationship between the bars and the video signal at the cathodes of the CRT. This waveform is present on all three cathodes. With the oscilloscope adjusted to provide a full peak to peak readout of the waveform at the horizontal rate, the 7.5 IRE setup bar will the critical area. Be certain this bar can be identified using the equipment available. If a 7.5 IRE bar is not available, 10 IRE may be used. It should be noted that bar patterns differ. Some vary from 10 to 100 IRE in various steps and in different directions, but most should have an identifiable 7.5 to 10 IRE bar.
Peak White Alignment 1. Apply a white centered pattern of 100 IRE 2% of the picture surface on a dark background. 2. Adjust for peak white at center of the screen. 3. Check Scaling Black Level, Whitepoint, Black Offset and Peak White adjustments. It may be necessary to adjust these alignments several times for optimum performance.
