How do I get the little blue light saying it has power? Connected and reconnected power source. Changed plugs, etc.

• Check that the transmitter AC power adapter is fully inserted into the wall outlet and the power cord from the AC adapter is firmly connected to the transmitter power input jack.
• If you're using the speaker power adapter, confirm that it's fully inserted into a wall outlet and the adapter power cord is firmly connected to the power input jack on the speaker.
• If you're using batteries for the speaker, check that they are fresh and inserted with correct polarity (+, -).
• confirm that the speaker is in 900MHz wireless mode-the indicator light on the front of the speaker should be either fl ashing or solid green. If the indicator light is blue, press the ON-OFF / RF-BT button on the back of the speaker to switch to 900MHz mode.
• confirm that the speaker is turned on and tuned to the transmitter-the indicator light on the front of the speaker should be solid green (not blinking).
• Check that the audio source component (stereo, MP3 player, etc.) is turned on and transmitting sound as it normally should.
• Make sure the volume on your audio source is turned up.
• Check that the speaker volume is turned up.
• Make sure you have disconnected the 3.5 mm audio in cable from the AUDIO IN jack.

Has anything changed with your phone's software? Have you tried deleting and repairing headset?

If you open the boom and long press the multifunction button does the headset light glow steady blue?

It looks like the power supply is damaged open it up and check for bad caps.

Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.

Hope that'll help you in some way.

I know my 990DSL wont charge if the serial cable is plugged in.

A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer (if USB connected)> reboot your pc > unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer (if USB connected). Then try to print again once the computer fully recognizes the USB connection or when the WiFi light on the printer turns solid green (if WiFi connected.).

If that doesn't help, try the steps below:

1. Disconnect the USB cable connecting the printer from your computer.
2. On your computer, go to Control Panel > Printers and Faxes.
3. Delete the Lexmark print object.
4. Reboot computer.
5. Re-brick your printer by pulling out the power supply - black box where the power cord is plugged into on the back of the printer, and re-plug after 30 seconds.
6. When the printer turns on, reconnect it to the computer.
7. Wait until your computer fully recognizes the USB connection. To check, go to Control Panel > Printers and Faxes. If you see a new Lexmark print object in the list, try to print a document to verify that the problem is fixed.

Green Indicator Light:

The default indicator light is green. When the Xbox 360 power supply light is green it means that there are no problems with your power supply. However, if you are having problems and the power supply light is green, this means that the console is faulty and you need to contact Xbox 360 support.

Orange or Yellow Indicator Light

When the Xbox 360 power supply light is orange or yellow this means there is no problem with your console but the power supply can't supply it with power.

To remedy this problem, first try unplugging the Xbox 360 power supply from the console and unplug the power cord from the wall outlet. You'll also want to uplug the Xbox 360 power supply from the power cord.

Wait for about five minutes and then reconnect everything. You might also want to try plugging it into another wall outlet without an extension cord.

If you are still getting an orange or yellow indicator light, then something is at fault with the Xbox 360 power supply. If this is the case, contact the Xbox 360 customer support to get a new one.

Red Indicator Light:

If the xbox 360 power supply light is red, then there is something wrong with the power supply connection. If this is the case, try the same solution as listed above of unplugging the power supply from the console, unplugging the power cord from the wall outlet and unplugging the power supply from the power cord. Wait for about five minutes and then reconnect everything. You might also want to try plugging it into another wall outlet without an extension cord.

If the indicator lights are still red, then there is a fault with the power supply. If this is the case, contact customer support about getting a new one.

No Indicator Light:

If the XBox 360 power supply light is not illuminating at all, this usually means that the Xbox power supply is not connected to the wall outlet correctly. On the other hand, it might also be a fault with the power supply or the power cord.

Either way, try the same solution as listed above for the red indicator lights. If you still don't see any lights illuminated after unplugging and then reconnecting everything, you'll need to contact customer support about getting a new power supply.

Green and Orange Indicator Light:

If the indicator light is flashing green and orange, this may mean that the console does not detect the AV Pack.

Disconnect and then reconnect the Xbox AV Pack. Make sure the connections are firmly connected. Turn your Xbox back on.

If the indicator light is still flashing green and orange, try another AV pack if one is available.

If the indicator light is still flashing green and orange, you'll need to contact Miscrosoft Customer support.

Flashing Orange Indicator Light:

If your Xbox console's indicator light flashes orange, this means the internal components have overheated and the Xbox has automatically shut down to prevent damage.

Turn off the console and let it cool for at least 10 minutes.

To prevent the Xbox from overheating in the future, make sure that it's not placed in a closed cabinet or on carpet. It's best to get the Xbox elevated off the ground where the PSU can have maximum heat release.

You'll also want to make sure the Xbox is not located near a heat source like the back side of a television, computer, monitor, or other electrical device.

then i would say your transformer has burnt out. unless there is a break in the cord.

Sometime these connectors from the desktop case front panel have labels indentifing what each connector/plug is for. From your description they could be a reset switch or LED indicators for hard disk or power light etc.
If the plugs are not labeled then trace the wires back to the front panel to identify what they are attached to.
When you connect the LED indicators to the motherboard and it does not light up when they suppose to, then turn the plug around 180 degrees.
The LED are polarity sensitive ie they only light up if the + and - leads are connected to the motherboard correctly.
