All Westinghouse LCD HDTVs include a V-Chip which permits selective blocking of television programming based on the content ratings system in use today.
The V-Chip feature allows for future updates of the content ratings system (although at this time we are unaware of any broadcasters or other program distributors who are using or planning to use a new content ratings system). A few Westinghouse TVs shipped without the ability to update the content ratings system in the event that such an update does take place. Westinghouse Digital is providing a firmware upgrade solution for those consumers who choose to enable the ability to update the content ratings system.
Please note that this update is not needed to operate your TV – the only purpose of the update is to allow the TV to use a new ratings system if one is developed.
If you wish to determine whether your TV is enabled with the capability to update the content ratings system, please see below:
If you do not see your model number or serial number range in either of the 2 sections below, your TV:
1) Already has the required V-Chip software for new content rating system
that may become available in the future.
2) Has an NTSC tuner that does not require this software by FCC regulation.
To determine your serial number range, please use the last 8 digits of the serial number, found on the back of the TV.

If your TV is one of the listed models below you can upgrade your TV via our online firmware download program. You will be re-directed to our Firmware Upgrade Page and asked to enter your full Serial Number. If you do not feel comfortable with firmware downloads, please call 866-287-5555 for customer service help.
