Hi,

I assume that when you replaced the battery that you did not remove the AC power, is this correct? If you did then perhaps the following may not resolve your problem.

Try the following to see if the firmware settings controlling the clock/radio have been corrupted.

Performing the following procedure means that you will have to re enter all the appropriate settings for the time and your alarm preferences as they will be lost.

Remove the backup battery, remove the AC cord from the wall outlet and then press and hold the Time Zone button for about 10 seconds. This will drain any residual power left in the electronics.

Ensure that the projector unit is in the upright position. (12 o'clock?)

Re install the battery and then reconnect the AC supply.

Enter the time, date and alarm settings etc., into the clock radio again and then press the Projection button and see if it works.

If there is no light emanating from the projector it may be either a faulty light or there is no power being supplied to the light. The no power to the light issue may be due to a number of reasons, e.g faulty projection switch, faulty light controller unit, etc. Either way, light or power, the unit would have to be opened to ascertain what the actual problem is.
