Hi all,
I've got a Philips DVD player has a very noisy SMPS that radiates quite a lot of noise on to the mains input. As a result AM broadcast band radio reception is absolutely impossible within the house, due to the noise it radiates.

I've fitted an external mains noise filter, (not a surge filter) but the reduction wasn't enough. Seriously thinking of junking the DVD player and getting a better one, but before doing that are there any cheap simple fixes, such as the standard three X class capacitors on the mains input (active to earth, neutral to earth and active to neutral) and replacing the electrolytics in the initial AC to DC conversion section of the circuit?
