PDF schematic of 6.76 MB pairing LB31J with 32LN5650, which corresponds to an LG 32-inch LN5650 television and its LB31J chassis code. Use it to follow the power supply, main board voltages, the T-con and panel signals, and the backlight driver when diagnosing a set with no picture or no standby. Check that the chassis label inside the TV matches LB31J, because one model may ship with different chassis. It opens in any standard PDF reader.
