OTVC LCD TV LG 42LK520 – T-CON
UC1 system control panel, the T-Con receives from board Main (Main
Board) byCN1 and CN2 dual 20-bit LVDS signals, which are processed in TFT
control signals, and then the connector CN4 and CN5 control the LCD panel.
Integratedcircuits US1 and US3 They are DC-DC converters and generate the
voltage required to support the display panel.
12V is supplied to the plate T-Con with plate the main connector CN1
(measurement of battery voltage can be make the fuse F1).
T-CON (control panel TFT) after removing the screen. Remember to mounting of applied screws to the
ground, when it is necessary Switching on the receiver.
Check resonator 10MHz quartz RS1.
Check the fuse F1 12V rails.

The values measured in the test diode were made after
disconnection of all terminals.
