Note:
Pin 10 measurement must have at least four digits of resolution following the decimal point. Example:
000.0000
3. Place the PTV into service mode for making electronic adjustment,
select the clock adjustment DAC CLOCK and change value to 128.
4. Calculate and set CLOCK based on the following formula:
Note:
TPA9 measurement will not change regardless of the value stored in CLOCK.
18. Convergence adjustment
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 Panasonic’s 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. / Convergence adjustment must be perform for 480i-p (same for interlace & progressive),
ZOOM 480i and 1080i.
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.
