rca p61960 home theatre premiere Repair.

[justRICHTOFEN]

Like the title suggests I'm looking for help trying to repair my old tv. It may sound silly and I should just buy a new tv, but this tv has a lot of sentimental value to me. The Tv will turn on and I hear white noise, but it has no picture. I could be wrong, but I believe the picture tube has gone out. The problem is I do not know what kind of tube i need, or how to replace it. Most of the Tv repair places were no help with this either. I've tried google and you tube, but most repair videos are in another language. Can anyone help me, particularly anyone who has some experience with repairing old tvs? 

    Also here are the spec for the tv: https://www.cnet.com/products/rca-p61960/

   Any help would be Greatly appreciated.
