Have TV Questions? Ask a TV Technician
Hello, Sorry you're having problems. The model number of the TV is indeed on a sticker on the back of the set.
Now the "HDC error" (high definition copyright) is typically caused be a communication error between the Uverse box and the TV. Ways to try to fix the error are to:
1)Reboot the Uverse box bby pulling it's power cord for 10 seconds and then plugging it back in (this refreshes it's software).
2) Replacing the HDMI cable with a new one. HDMI is digital and not all cables are equal. Even a brand new cable can cause this issue.
If those steps do NOT fix the issue then I will need the following info:
1) The model number off of the back of the set.
2) The age of the set.
3) Have you successfully tried any OTHER sources connected to the TV via HDMI that ARE working?
If you need further assistance let me know. Before you go, PLEASE DO click at least a 3 STAR RATING, at the top your screen. That is how I am credited for my efforts by the site.
