I have a Sony CDP XA1ES which is about 9 years old. I have always liked the player but the left channel sometimes fails to come on when the unit is turned on but a light tap brings the channel to life. I have checked many things and I am hoping the player will last until March when it will be replaced. Has anyone had experience with this player or have advice on what to do. Until March I plan on smacking it lightly. Thanks for any advice. I know I should be happy for this long amount of enjoyment.
