Q7120 (KIAxxxxx?) is a 4-pin switched 12V LDO which supplies the 12VDC to to the T-CON board via PNL -12V pin.
Are these your boards?

You need to report the Voltage reading of each pin of the PD connector, you must put down the pin name and follow by the Voltage reading of each pin when TV is OFF and when power switch is activated.
Your TV has many boards and since I do not have TV in front of me to look at to see how all the boards are connected together so please follow the simple request if you want free help.
