Push the "menu" button on your remote Tab over to the "time" menu check all the settings in there, turn of the sleep timer etc... Try a factory reset Push the "menu" button on your remote and go to settings, scroll down and push reset. I hope this helps

Hi, please double check that your product was created for the country that you're using it in. If not, please attain an adapter that ensures the voltage and current are what your country's power socket require. The proper current and voltage of your boombox can be found in the manual- usually in the front. Thank you.

Rina - Are you sure about that product ID? I found nothing with CDX prefix - perhaps you should try this - http://www.samsung.com/us/business/support/owners/product/SCX-3405FW/XAA This is as close as I could find and I've been servicing laser printers of many manufacturers since 1998. Your question does not explain the problem you are having; please try to include that in your next question - I have to know what you are working with before I can give you an answer.

What about it?

Try 0000... it's the default code I guess for most samsung tvs.
