Adjustment

1.  Receive a Cross Hatch pattern.

2.  Connect an oscilloscope to TPLB1 on LB-Board.

3.  Adjust B-LIMIT so that the waveform A is 156 ± 2V.

 

 

The convergence adjustment is set separately for each 50/100Hz/ 60/100Hz input (NTSC, PAL/ 
SECAM). The following explanation uses the PAL mode as an example, since the same procedure 
applies to the convergence adjustmentfor NTSC mode.

When replacing the following Parts.

 

IC7301 (EEP-ROM in A-Board)L551 (Pincushion Coil)High Voltage Producing Parts Other Parts (If 
change the convergence)

Create an Adjustment Sheet by tracing the following specifications in their actual size on transparent 
film or tracing paper.Then adjust the convergence.

When replacing one of the CRT´s.

 

Adjust the convergence for each of the 50/100Hz and 60/120Hz inputs so that they are aligned with 
the other colours.

Helpful Hint

 

All positions which have been adjusted are recorded within P-2 for NTSC data and P-3 for PAL data 
of the memory.This data can be copied to P-4 memory area, allowing you to perform the adjustment 
of P-2 (NTSC) and P-3 (PAL).To perform these adjustments,push the SEARCH button on the remote 
control, and manipulate the position [

] and [

] button and the "N" button as instructedby the On Screen Display in Fine Convergence adjustment.

All of the Convergence Control Charts have been listed for the remote control buttons after the 
Convergence Adjustment Procedure Please refer to these. (Page 29)
