Hi, If you don't mind sending it to Marantz service center in Mumbai, they can get it done. You can try alternate addresses from this link, near you. Just have a word with them on the part availability and cost, prior to sending. I had availed their service once for amp, and found them to be quite professional.

Since in our earlier conversation you had mentioned about getting a network player with DAC, you can use that as a source instead of this CD player as most of your music is in hard drive/streaming. There was a NA6005 for sale in this forum by a member from Delhi. You can check with him if it is still available and have an audition.
