Why LED light continuously blinks - Lands Phones

1. If both round and long LED's are blinking, unplug the opener motor for five seconds, and replug. If the lights go back to normal, it was just a program error. If they both continue to blink, it's probably not user-serviceable.
2. If the round LED is blinking and the long LED is off, it is usually the door sensors that are obstructed or knocked out of line.
3. If the Long LED is blinking and the round LED is off, it is usually a bad roller or hinge that won't let the door move freely, something stuck in a track or a bent track.

Continuous blinks of standby LED indicates a main board fault. Just check this set after a reset. If it do not help you, replace the main board.
To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset.

There 3 light on the printer that able to indicate to user when problem occur. Which is the light u mean here?

1st button light blink rapidly = the printer may be out of paper, so load more paper and press the 1st button itself to continue. Or may be paper jam is occur, so clear the paper jam and press the 1st button light itself to continue.

If 1st button light blink slowly = mean the cartridge carriers are stuck, so raise the scanner unit and remove any object blocking the path of the cartridge carrier, make sure the cartridge are closed and installed properly, then lift the scanner unit, gently push the scanner support towards the cartridge carriers, and carefully lower the scanner unit until it is completely closed. After that press the 1st button itself to continue.

If 2nd LED light blinking = the color cartridge need to be replaced soon.

If 2nd LED light is ON = the color cartridge need to be replaced immediately.

If 3rd LED light blinking = the black cartridge need to be replaced soon.

If 3rd LED light is ON = the black cartridge need to be replaced immediately.

What operating system are you using? When the power led continues to slowly blink, that means that the laptop is in standby mode and not fully shut down. In Vista, if you hit the power button on the laptop or the power button under the start button, it is configured to go to standby and not shut down. Make sure to hit the arrow all the way to the right and select shutdown from the list of dropdown options.

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.

If blinks continue without any pause, the main board is faulty.
