When trying to turn on the phone it will not light up or power on.
If the phone won’t turn on at all and won’t charge then this can indicate a bad battery. Try taking the battery out and putting it back in and then letting it charge. Also, check the phone display to ensure it doesn’t say “No Battery”. If this message is displayed this indicates there is not battery or the battery is not properly connected. Verify the wires from the battery are connected to the port on the phone. If this does not work you may need to replace your battery.
First try to let the phone charge for an hour and try to power on the phone again. When docking the phone the charge LED light in the top left corner should light up indicated that the battery was dead and it just needed to charge. If it does not light up then this could be a bad battery or other problems. You may need to replace your battery with a new battery.
When turning on the phone there is an unusual noise or no noise at all.
Buzzing noises on the line could indicate incorrect wiring or wires touching metal. In this case you may need to find the correct wiring diagram for that particular phone and verify the right colored wires are connected in the right spots. Also, check to see if any wires are touching metal. This could cause them to ground and the phone to make this noise.
No noise could indicate that a wire is not connected or a wire has shorted. Check to ensure the wires aren’t touching each other and that they are properly covered with insulation. If no noise or low volume during a call check to ensure that the volume is turned on. Also make sure the mute button is not enabled. If this does not resolve the problem this could be a bad speaker. Here is a Speaker Replacement guide.
This can mean the wire is wet or there is a loose connection. Check the wires and look for loose wires or moisture.

When the phone is on the charging unit it will not charge.
Check to make sure that the charging cable is securely connected to the base and to the wall outlet. Also check to make sure that the contact pins that connect the base to the phone are free of debris. If the connections are working, but the phone is still not charging, this could indicate a problem with the inside of the charging station. Try charging the phone on the other base to ensure that it is a problem with that particular base and not with the inside of the handset. Also, check the fuse on the main base. Here is a Fuse Replacement guide if the fuse is blown.
If the phone will not charge when placed on the charging station, try placing it on the other charging station. If the phone still won’t charge, it could indicate a fault inside the handset. You may need to replace the handset provided that the battery works fine. Also try swapping the batteries between handsets to see if it’s a battery problem.
If the phone won’t charge then this can indicate a bad battery. Double check to make sure the charge LED in the top left corner is on indicating it is charging. Try taking the battery out and putting it back in and then letting it charge. If this does not work you may need to replace your battery.

If “No Line” is displayed on the phone screen check to ensure the landline is properly plugged into the port on the phone base. Also, ensure the wires leading from the phone to the landline outlet aren’t damaged. Check to make sure the landline ports aren’t damaged. If none of these resolve the issue you may need to contact your phone landline provider. If the port is damaged the next steps would be to fix the port. A repair guide might be necessary.
