These configurations, when damaged, can result in an unstable connection, which also gives rise to this error. 

2. Insufficient Power

Oftentimes, if a power outlet is not being able to give the required amount of voltage, then the signal amplifier will not receive the voltage. As a result, this error occurs. 

3. Loosely-Attached Cables

If the connection cables are not attached tightly, then without a fail the connection will not establish.

Solution 1: Reset The Equipment

It is likely that maybe certain configurations can be damaged which is why the connection is not getting through. For that, consider resetting the launching process. 

First, take out all the connection cables from the TV, internet router and etc. Now, press and then keep the “Power” button of the Internet Provider, on hold for no less than 30 seconds. 

Now put the cables back in their respective slots and then let the internet connection come. Turn on the TV and try streaming again. Check if Xfinity rdk-03003 still shows up or not. 

Solution 2: Check Cable Connections

Oftentimes, the cable connections get loose over the course of time. Or it could also be that the cable or the input port is damaged. To find out which one is the problem,

Unplug all the connection cables and then insert them back in, tightly and firmly this time. 

Check if the error still comes up or not. 

If you have a different HDMI cable, then use that to generate a connection and then check if you get the error or not. 

However, in both cases, if the connection does not turn up then go to the last option below.

Solution 3: Change Power Source

It is possible that the power source that you are using might not be giving out the required voltage. So if there is less or no voltage passing through, the connection will not establish. 

Hence, try using a different power source, which is nearby to the device. Using a multimeter, check the amplifier signal strength. However, it is advisable to do this with the help of an expert as failure to this, or any simple mistake might be fatal.
