Preliminary Information 42PQ30
LEFT AND RIGHT X BOARDS SECTION
LEFT AND RIGHT X BOARDS SECTION
The X Drive Boards deliver the Color drive signals to the Vertical Grids.
The 42PQ30 has a Left and a Right X-Drive board. Each with 6 Connectors to a TCP.
And each TCP with 2 buffers.
Each buffer controls 128 vertical grids lines.
Generally speaking, there isn’t many active components on the X-Drive Boards
(Printed Circuit Boards). So they are not prone to failure.
In this section the X-Drive will be discussed and information given allowing the
service technician to determine if a failure has occurred in the X-Drive section.
X-BOARDS CONTROL THE VERTICAL GRIDS WHICH DETERMINE THE HORIZONTAL PIXEL COUNT.
TOTAL HORIZONTAL GRIDS 3072. TOTAL HORIZONTAL PIXELS 1024.
Total Buffer Count = 24
(TCPs = 12 @ 2 buffers per/TCP)
Total Output Pins = 3072
(128 per buffer X 24 total)
Total Pixels (Horizontal) 1024
(3072 / 3) Three cells per pixel (Red, Green and Blue)
