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.

I have a satellite L755 and my HDMI port does not work any more


Plug in a HDMI cable to another device.
Go to Control Panel, then Pick device Manager.

Check the ports list for your HDMI port and see if it is "disabled". If so you can re-enable it on the same screen with a button.
If you cannot see it go to the tab marked View and select all hidden devices.

Hdmi not working on tv


You can not re-enable them? It will be very difficult to run a jumper, or stand in between the system and the tv.

The outputs for monitors and HDMIs are disabled to conserve the battery even if it's plugged in. Somewhere in wour disply properties, you need to turn on the HDMIoutput. All pc's are different. On my Dell it is function and F8. Yours is that simple but not likely the same. Try your support page.

Are you aware that all the new HDMI devices have interactive technologies . For eg: if you are watching cable TV and switch on your Blue ray player connected via HDMI, you will notice the TV will automatically switch to that HDMI input with you having to pick up the Tv remote and switch manually. Some find it irritating, but you can disable that function in your system Menu. Panasonic calls it Vierra link / Sony calls it Bravia sync etc.....

I have a mitsubishi 52525 and it has one hdmi port....how do i select the tv to use that port?


Hi:
On mitsubishi models something has to be connected to the port for it reconize that the port has a signal connected to it. Once a signal is connected the port will be highlighted in your ment, if not then you may have that port turned off or disabled in the menu. Also make sure the unit you are connecting is turned on so that a signal is inputed to the HDMI port.

I have a cable box connectin and cannot choose HDMI as a source. I had HDMI as the source for about two years and then something must have changed. I have verified the HDMI cable is not the problem. Page...


The manual is telling you that your "source", whatever you are connecting to a particular HDMI port, needs to be turned-on in order for the TV to detect it. Make sure that the HDMI cable plugged into the correct HDMI port for each device (TV & cable box) and that the cable box is on. Does the cable box HDMI port need to be selected in order for it to be functional or is it on all of the time? Check your cable box instruction manual for details on the proper way to enable (turn-on) or disable the various outputs if needed.

Let me know if you need additional info.
