Hi. Sorry to read of the difficulty which you have written about above on your DN-S3700.

Could you clarify please, is it just the rectangular, main display of your DN-S3700 which is not working, or is the whole player showing no signs of power? eg: If you plug it into power, turn on the power switch on the back of the unit, do any of the illuminated buttons light up? are there any noises from the CD drive as if it’s spinning? will the unit respond to the eject button if a CD is already in the player? Will the unit take a CD in if there is not a CD already in the player? (Warning, be careful not to try loading a CD into the player, if a CD is already in there)

Thanks in advance for clarification of the above.
