Turn PTV on and allow it to warm up for 30 minutes prior to perform adjustments (apply a WHITE PATTERN).
Helpful Hint:
EEPROM jig can be used to adjust convergence, by copying convergence adjustment from a convergence adjusted PTV
to other. Refer to EEPROM copy jig section on this service manual. Also EEPROM copy jig can be used to back-up the
data before to performadjustments.
NOTE:
1080i, 480p, 480i pattern can be obtained from Panasonics TU-DST51 set-top box DTV decoder.
IMPORTANT NOTICE:
It is strongly recommended to first read and understand the following section prior to make any adjustment.
This PTV uses the scheme described below to correct for misconvergence of the three CRT projection tubes. There are
various modes to this operation.
Preparation:
Place the convergence alignment template (see Convergence alignment template section on this manual) over the PTV
screen. Align the center lines of the template with the mechanical center markers on the PTV screen frame. If the template
is not available,create one using the dimensions provided in Convergence alignment template section on this manual.
Remote control must be used during the procedure.
Procedure:
Apply the convergence alignment template to the PTV screen frame to converge the green raster only. Remove
the convergence alignment template following this alignment. The red and blue rasters can then be aligned to the green raster.
Raster Set-Up:
1. Enter to service mode (red CHK).
2. In SET-UP (menu) enter to Other Adj. menu and set CONVERGENCE values (GH, GV) to 0.
3. Cover red & blue lens with caps.
4. Apply a pattern to adjust with 1080i HD format:
5. Select COARSE DAC, then press ACTION to enter to Coarse adjustment mode.
6. Press 0 key on remote.
7. Press ACTION key on remote to enter to TEST_POS mode.
8. Move pattern by pressing VOL right - left and CH up - down so that the cursor center overlap monoscope pattern center.
