Sound gone on RCA F35750ST TV

All, I need some help, I have an RCA TV, Model: F35750ST and the sound has gone on it.  The Warranty is up on it and I don't want to get rid of it, does anyone know how I can fix this or where I can get information on how to fix it?  It's a pretty big size TV and don't want to get rid of it.  Anyone that can help me out I would greatly appreciate it.  Thank you, Shannon
