The solution is to buy a new radio. Clock radios cost as little as $12 on Amazon.

    I am 24 years old and this is the oldest item I still have. Got it when I was 5 or 6 for Christmas and would be upset if I ever encounter a problem with this tech mech late 80's alarm clock. I'm still wondering what year it actually is; I can't seem to find any information on that.

My radio stopped working after a power surge tripped the breaker for the outlet it was plugged into.

I have had several different makes of clock radios and all said that it was battery back up for power failure
none worked and all settings had to be redone
power surges do not trip breakers as they are in effect a fuse to prevent damage to the wiring in a dead short situation or when a unit fails
even surge protectors will still pass power after a surge but will no longer protect against another surge

My Bose radio will not turn on. I plug it in and the radio lights up and then it goes dead this all happens in about 60 seconds...any suggestions ? I am in Xian China the radio worked fine prior to coming...

If that unit came from the states, the power would be 110V and in China tjhe voltage they use is 220V.
That means, you have to check the fuse in the radio, replace if it is already open.If the fuse is still okay, the power circuit has a burned parts.
My advise is to send it to a electronic tech or the nearby service center.
Hope that helps!

Over-voltage connection - 220v - instead of 110v

That thing is fried.If you can do your own electronic repair,there are a few components where the plug comes in that would be cheap to replace.Without a solder gun and voltage meter though I would replace.

Static occurs when movement in the room

This problem sound like you have had some damaged to the earth ground in your electrical wiring system. You should have a electrician thoroughly test the electrical outlets and wiring in your house or apartment. You should be very careful using any electronic equipment with a problem like this. Your Clock/Radio should be unplugged from the a/c wall socket and the internal battery removed. This will allow the microprocessor that controls all the Clock/Radios functions to reset. The Clock/Radio should be left unplugged for a period of a few hours to discharge the microprocessor. This will help the microprocessor to heal itself from the lightning strike. You will need to get the ceiling light fixed. There might be a shorted wire or something causing its failure. This could also be a burnt wire. Lightning power overloads can be very dangerous to all electric and electronic equipment. Try putting your clock Radio on a rubber mat to isolate it from any traveling static electricity that may be in the air. Try to discharge any static electricity that may have built up on your hands by discharging it on a piece of metal like a screw driver or metal surface.Do this each time before you try to use the clock/Radios button functions. This will stop further damage from occurring during you handling of the Clock/Radio. After discharging the microprocessor, reassemble the battery into the Clock/Radio and plug in the wall socket. The operation should return to normal. If not you may have more serious damage to the microprocessor. You can call the Emerson Customer support at this telephone number 1-800-898-9020. Give then the make and model number of your Clock/ Radio and ask them for assistance. I hope this information helps you with your problem.

Clock radio

Unless thate is an internal fuse it that blew, most likely it will be more expensive to repair than replace. The transformer primary winding is probably burned out. You have nothing to lose, take it apart and see if there is a fuse. If so, replace it with the EXACT same value as the original. If not, its not worth fixing.

You didn't say what the symptoms were, other than it didn't work anymore. I am assuming it is completely dead.

Please let me know if I can be of further assistance to you.

Good luck!
