Your red CRT is most likely shorted and will need to be replaced. If you need more assistance please let me know.

Yes the red tube is shorted. I will post a link to the site where I work as they have an entire AV48WP30 with a bad tuner they are selling parts off of including the Tubes. they also provide free info on how to switch out the tubes as a unit which is a fairly easy job. Heres the link.
