Baby monitor replacement battery

Either the battery is dead or you need to change the sound setting that keeps unit off when it does not detect sound to protect the battery.
Another person said.
".We have this one. It must be in the sound activation mode, which helps to save the monitor's battery life. If it's in that mode, you'll see what looks like a crying baby icon along the top of the screen and the screen only turns on when sound is detected in the room.

To turn the mode off and keep the monitor on all the time, just press the Menu button on the right (in the middle of the arrows), press the right arrow until you reach the crying baby icon on the far right (so the icon gets big), press the Menu button, and a check mark and an X will appear - the X will be pre-selected and appear red. Just press the Menu button again to select the X and turn that mode off. Once back to the Menu screen, arrow up to the Return button on top right and press the Menu button to exit."

The unit may have a back-up battery installed that is low on charge. Replace the back-up battery. The unit is probably still working because you have it plugged-in.

• Choose a model with a frequency of 900 MHz or higher so that it will reduce the interference and increase the clarity
• Go wireless
• A video monitor
• A model with "low battery" indicator
• A model with a sound activated light so that it flashes when it detects noise
• The smaller the receiver, the more you can easily carry it around the house

Less than a year old = go for a warranty repair or replace, Use the warranty while you can as you'll end up with either a working or new unit.

here is the manual http://www.homedepot.com/catalog/pdfimages/ee/eee691a0-e88c-41d2-8df3-327e03f45222.pdf

I dont think yours is a battery issiue, I would call the manufacture on the first page of the manual.
although if you dont replace the charge on the unit at least monthly the batteries wont be healthy. If you are going to store it make sure the alkaline batteries are out of the mic or transmitter unit. and you can unplug the rechargeable one as well. this will help the battery life.

We had the same exact problem, tried replacing the rechargeable batteries but to no effect. We called Phillips directly and they were very nice and are shipping us a replacement unit (they discontinued this model and I suspect this is a known issue).

You might have to pair the parent units to the base units. here is the manual, look under troubleshooting:
