Red 4 Flashes Green 4 Flashes Power Failure

Off 3 Flashes Reverse Comms Fail In Use

I have one of these units and it has had its fair share of troubles, but great when it is working. My latest issue is the the flap on the indoor unit doesn't open!

This generally works for me. Pull out the isolator outside on the wall or disconnect at the breaker. Leave for a couple of hours. Reconnect and wait 15 minutes. If you are connecting via the isolator you will hear relays clicking and solenoids rattling as the unit goes through a Self Test procedure, then try normal operation.

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.

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

Please follow the below troubleshooting steps: 1. If the Television is plugged into a surge protector, remove it from the surge protector and plug it directly into the wall outlet. 2. Try connecting the TV to a different AC wall outlet. 3. Try power resetting the TV. To Reset the TV, disconnect the power cord for a short period of time (approximately 1 minute), then reconnect the power cord and power ON the TV. 4. If the issue still persists, TV will require service.

Hi
It maybe one of the fuse gone.

You have to change the fuse:
The fuse is 250mAh and 3/4" inch long (20 mm) round glass with metal ends. The electrical contacts are not in the cartridge but inside the printer: There is a plastic fuse holder on the cartridge, even the starter cartridge. You just simply pop it into the holder. This will stop the flashing red LED and the system tray will say the cartridge is full.

Ok the lightning bolt is your power indicator: solid green-charging, Flashing green-fully charged, flashing red-low battery, flashing red three times the once green-bad battery. the "trash can" looking one is your hard drive activity indicator it will flash while your hard drive is reading and writing.

Disconnected all external power i.e. power lead, extension cord and wall socket...then reconnected...has worked perfectly since.
