Try this, using the Panasonic remote, wait until the notice about your lamp goes AWAY (it wont work with the message still up).
Hold the volume down on your tv while holding the split/play button on the remote.
You will get a notice about 4-5 seconds later that it was reset.

Try cleaning the contacts with a cotton swab and som isopropyl alcohol.
Let those dry.
Use a paper clip, or other small pointy object to clear the area around the contact points on the light so the recharger can fully "snap" into place.
Attach a battery you know has a good charge.
Turn on the light.
Did the light turn on?
If so, great, turn it off, and if it is blinking, let it recharge.
If it didn't turn on, isn't blinking and won't hold a charge after this process, return it to Blackburn and enjoy the benefits of your lifetime warranty.
