Panasonic LED 42AS630D Power light is flashing.... the TV has no picture the remote control is not responding and the TV's front LED light is blinking...?


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to, is the Front Panel header.

On your motherboard there are two.
JFP1 and JFP2.
Junction Front Panel 1 and Junction Front Panel 2.

JFP1 is on the Right side of the motherboard, down in the Bottom/Right corner.
It sits Vertically on the motherboard.

Two columns of contact pins.
5 on the Left side, 4 on the Right side.

The pins on the Left side are numbered ODD.
The pins on the Right side are numbered EVEN.

Starting on the Top/Left side, coming down;
Pins 1, 3, 5, 7 and 9.

Starting on the Top/Right side coming down;
Pins 2, 4, 6, and 8.

A) Pins 1 and 3 are for the HarDDrive activity LED light.

A) Pins 1, 3, and 5 are for a THREE wire Power On LED light.
I assume Pin 1 is for the Negative wire ( - ), and Pins 2 and 3 are for the two Positive wires.

It's for a dual color Power On LED light.
