IC801’s heat sink when the HOT ground symbol is used. Otherwise,
use COLD ground (tuner shield, IC451’s heat sink or FA2).
Component and Voltage Test Points
Note:
Components and test points within doted areas are located on trace
side.
B+ voltage check
1. Set the BRIGHT and PICTURE to minimum by using the PICTURE
menu.
2. Connect the DVM between TPD145 and cold ground.
3. Confirm that B+ voltage is 144.7 ± 1.5V. This voltage supplies B+
to the horizontal output and flyback circuits.
