LCD Panel Controller Board
The Frame Rate Converter IC
IC102
receives from the Main Boards LVDS Video Signals at
P802
, which is a 51 pin cable. The Video Signal is a 20 Bit (24 pin including clock and data lines)
LVDS (Low Voltage Differential Signal) which it processes into TFT Drive Signals. These signals
are from IC400 and IC500 to connectors
P805
and
P806
and then to the LCD TFT Panel.
T-CON/3D B+:
12V is supplied to the T-Con Board from the Main Board
P7802
and
P7802.
Delivered by two connectors
P802
and
P803
easily measured at the Test Point just to the left of
these connectors, (L801 and L802).
There is a primary DC to DC converter (
IC600
) that creates several voltages;
(8V Measured at pin 11), (25.63V Measured at pin 8), (6V Measured at pin 2), (16V Measured
at pin 42), (3.3V Measured at pin 23-24 or L601), (-5V Created by D601 on the back side of the
board). Another voltage is generated for the panel (8.17V measured at L701).
These Voltages can also be measured at the ribbon connectors delivering signals to the TFT
panel using TPs.
P805:
“16V” pins 1-2, “3.34V” pins 4-5, “8.17V” pins 7-8, “-4.9V” pin 11, “25.63V” pin 16, “6V”
pins 18-19, “8V” pin 21, “15.75V” pins 23-24 and “3.33V” pin 45.
P806:
16V pins 79-80, 3.34V pins 76-77, 8.17V pins 73-74, -4.9V pin 71, 25.63V pin 66, 6V pins
63-64, “8V” pin 61, 15.75V pins 44 and “3.33V” pin 36.
Also, See the 11X17 Foldout (Interconnect Diagram) for more details.
