I own a Sony Bravia which has TV Guide service built in. I hope you find the time and information I provide to be valuable and will honor the good faith system of this site.
Use the Guide to find the program that you want to watch.
The Guide allows you to organize and personalize the program listings.
I have done the initial setup, but the guide still doesn't work.
Please be aware the answer to your question may not be good news and the procedures that are required to solve your problem may be complex and could involve replacing parts that can be expensive.
Solving your problem depends a lot on your ability to follow directions very carefully, be patient, and continue the communication process with detailed responses.
