You might have already tried this, put whenever there is a problem with this modem, the cable company always suggests unpluging the power supply, wait 30 seconds and try rebooting. Also, your compuer software will try to locate the problem for you. If all else fails, contact the cable company and they can check the modem from their end.

My check engine light keeps blinkin on my 2003 chevy impala and keeps shakin


Take it in, a blinking check engine light is not a good sign. Solid yellow is ok, blinking yellow or red is in need of service. Get the codes checked asap.

When I switch my PS3 on, it just switches itself off to 'stand by'. I did have another problem with the PS3 in the summer 2009 when my driver went and sent it to Sony to fix it. I had this problem since...


if there is a flash of a yellowish light and then followed by a blinkin red light read on:
You have the dreadful blinking red light of death. Long story short the system is broken due to overheating and heat damage to the motherboard and you have a few options:

  1. (do what you have already done and) send the system to sony and receive a refurbished system for $150.
  2. find a local to do it for much cheaper
  3. watch vids on the web (youtube.com) and fix it yourself but it is fairly difficult.
  4. buy a new ps3.
I hope I have helped and please feel free to ask me any questions and let me know how it goes.

My Motorola Sb5101 modem will not let me access the internet, the send light constantly flashes and i can't attain any internet connection.


If you have the following lights :
Power light - on
Receive light - flashing
Send light - flashing
Online light - off
PC/Activity - on
Standby - off
Then your Network Access is OFF - modem is successfuly registered but Network Access Control is disabled via DOCSIS configuration file.

Call your internet service provider....

Two light are blinkin' in from panel. and tv


This seems to be a common problem. I have the same issue. Repair man says its a power supply (he thinks). When the lights start blinking, press the power button on top of the tv (not the remote) and most of the time it will come on and work. I am going to try to replace my power supply and see if that fixes the issue. If so, I will update this post.

Receive, send, and activity lights are all blinking but online light is off


Power Cycle the modem if the 4 lights do not go solid you would want to contact your cable provider to ensure signal is being received properly to modem.

Only 3 Lights Come on, Not online though.


That online light goes solid when your ISP completes the registration process of your modem. If this process fails, there are only 2 possible reasons. The first is your modem MAC address is not on your account with your ISP, which cannot be your case because it works on a different outlet. The second reason would be what is called ingress on the outlet. Ingress is caused by a bad outlet or more frequently a bad connector. Make sure inside your connector is clean and free of metal shavings. The problem you are describing is actually rare because usually if your having cable issues that cause a registration problem, you don't usually get a send light.

By the way, just because your tv works on that outlet doesn't mean your modem will. Your modem runs off RF frequencies that your TV doesn't come close to.
