Not positive, but my uncle had the same problem. He said a repair tech came out and changed a bulb inside the tv ( it burned out). He lost picture and sound also. It just happened to my moms tv also.
I Have No Picture And No Sound On My Sony KV-32S45. The Red Stand By Light Continues To Flash. When The TV Stopped Working There Was No Popping Or Burning Smell. Can Anyone Tell Me What Is Wrong?
Is this t.v. High definition capable. If not I would say to buy a new one. Here is a discussion on this same problem . I believe it would cost more to have fixed than to buy a new one. Www.fixya.com/support/t119695-Sony_kv_32s45_no_picture
