My tv model magnavox26mf231d/37 shows hdmi is disabled and the hdcp authorization failure.
This could be a problem with the cable box or other set top box and not the TV. It's known to happen with Samsung cable boxes from Cablevision.
First try resetting the TV and set top box by unplugging both. Remove the HDMI cable from the TV and the set top box. Reconnect the HDMI cable. If you are using a Redmere or similar HDMI cable, make sure that the end labeled TV is connected to the TV's HDMI port. (These cables have additional electronics and are not reversible.) Connect the power cord to the set top box and wait 30 seconds to a minute. Then plug in the TV. To ensure the set top box does the correct handshake with the TV, turn on the TV first and set it to the HDMI input. Then turn on the set top box. See if this fixes the issue. (On some cable boxes, this can be a temporary fix. You may need to have the set top box replaced.)
If the above steps don't help, try a different HDMI cable. If that doesn't solve the problem, then the set top box is faulty.
I hope this helps.
