Standby light mode

The Huawei MA5800 does not support active/standby mode, but only load sharing mode. The MA5800 has a distributed architecture. When two control boards are configured, the active and standby control boards carry services at the same time to effectively utilize the bandwidth of two control boards. Huawei MA5800 X15

I don't have service mode specifications but I do have a Samsung and looked around for how to get it in service mode some time ago because the HDMI cables somehow disconnected themselves a lot. Thought it was an electronic problem but it turned out to be a parenting problem instead SO I have never used this information and can not vouch for it. I cut and paste it from a note I copied from a forum entry to use at your discretion:
First post:
To enter "Service Mode" Press the remote - control keys in this sequence :
From Standby Info-Menu-Mute-Power On
- The buttons are active in the service mode.
Remote - Control Key : Power, Arrow Up, Arrow Down, Arrow Left, Arrow Right, Menu, Enter, Number Key(0~9)
Careful though there are things you shouldn't touch in this menu.

Good luck. Just a basic suggestion you probably don't need: keep track of any changes made by writing them down so you can put it all back if you have to.

How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

That is usually a problem with signal levels or the modem isn't set properlly. I don't know who your provider is but you should get hold of them and get them to fix it. They should send a tech out to check your signal. While they can check the modem remotely it does not provide them with the same information that a onsite check does. There is nothing you can check or change as a end user.

This can be signal levels, or signal quality (noise), or bad cableing and so on.

It occurs when your wii in the Standby, but WiiConnect24 is enabled with Standby Connection is enabled. the content can also be received when the Wii is left in standby mode.

WiiConnect24 can be turned on or off via the setup setting. While the console is in standby, the power LED indicates the current status of the standby connection,

• Red indicating Standby - wiiConnect is off,

• Yellow indicating Standby - Connect mode is on. If you hold the power button for 3-4 seconds, the Wii goes into standby mode with Standby Connect off. and WiiConnect24 will not operate until the console is turned on.

I found an original replacement remote for a Loewe ARC332PB at remotes.com

I have a Windchaser fan mode FTR184 also and it is in the same indicator STANDBY mode and now it will not come on and we have the remote, how do you fix this?

If your bulb finally reaches it's end before you have the chance to replace it you unit will shut itself down and go into a permanent standby mode. Changing the bulb alone will not remedy the issue. The solution is quite simple but not posted in the manual or anywhere else that I could find for that matter! All that is required is to hold down the HELP button on your remote for 10 seconds while aiming at the infrared sensor on the unit. This will reset the units bulb timer and remove it from the standby mode.

Modem and coaxial cable abnormally connect, or probably loosing power from internet. ask your local ISP
