Second level tv has a signal but the main tv on first floor has no signal.


Hello! It sounds like there are a few things that could actually be going on. If you are getting no picture on the TV(you have a black, blue, or snowy screen), you will want to make sure that the TV is on the correct channel and/or input. You will want to be on channel 3 or 4, and possibly on a Video 1 or 2 or HDMI 1 or 2 input. If that doesn't work, then try unplugging the receiver from the power source for about 10 seconds. If you are still not getting a picture, let me know!

If you have a signal loss message on your screen (Signal has been lost, Partial SIgnal loss, COmplete signal loss, or Acquiring signal), you will first want to unplug the receiver from the power source for 10 seconds. You will get the Acquiring singla message as the receiver reboots after you plug it in, but that should only be about 5 minutes at the most. If you get the message after 5 minutes, you will want to make sure that all of the cables going from the back of the receiver to the wall are tight. If that still doesn't do it, please let me know!

This has hopefully been resolved for you, but if not, here are some steps to go through. The black box that comes on the screen is usually signaling that closed Captioning is activated on the tv. Closed captioning does not run through the DISH Network receivers, so you can turn that feature off in your tv settings. The fuzzy picture could be a few things. You will want to check that all of your cables on the back of the receiver box and tv are tight as possible, and also make sure that the tv is on the correct channel. If you are in the room with the receiver, the tv will need to be on channel 3 or 4, and sometimes an input; usually video 1 or 2. If you are in a number two room, where there is no receiver, than you want to make sure that the tv is on channel 60 or 73. I hope that this helps!!!!!

Suggestion doesn't seem to apply to my tv


Service menu settings and resetting if still nothings happen. Then DVD works fine and then the signal strength is 95%. Then the problem is your cable card provider. They blocked your channel this is the common problem of card deactivation. Just try this, take the cable connection and put an ordinary outdoor antenna, if still not working then the problem is in the signal board , but if it's works ok then the problem is cable card activation...

Checking the Diagnostics screen 1. Make sure the RF cable is plugged securely into the CABLE connector (not the ANTENNA connector) on the back of the DVR.
2. Tune to a channel that is having a problem and press RECORD to lock the tuner to the CableCARD.
3. Press the TIVO button and select Messages & Settings > Account & System Information > Diagnostics. Look for the number of the problem channel, and then look below it for the Signal Lock setting.

• Signal Lock: Yes means the DVR is detecting a signal for the channel. In this case, the DVR usually cannot display the channel because either the CableCARD has not been activated or during activation the card did not receive the provisioning necessary to display the channel. For more information, go to
Step 4: Determining if the CableCARD is activated.

• Signal Lock: No means the DVR is not detecting a signal on the channel. If this is happening for only one or a few channels, this channel may not be in your lineup. For more information, go to
How Do I Determine Which Cable Lineup Is Mine?

If you see Signal Lock: No, and Test Channels could not display any video on the CableCARD, use the following procedure to check the signal connections.

Checking signal connections 1. Partially eject the CableCARD(s) so that they are disconnected from the slot.
WARNING: If you remove the CableCARD(s) completely, you must take care to replace them in the same slot. Switching slots will unpair the cards; to re-establish pairing, you will need to contact your cable provider.
2. Press the LIVE TV button on the TiVo remote control. Do you see video?

• If you see video, the CableCARD activation was not successful. For more information, go to
Step 4: Determining if the CableCARD is activated.

• If you do NOT see video, go to Step 3.

3. Plug the RF cable connection directly into your TV. Do you see video? • If you see video, go to Step 4.
• If you do NOT see video when the cable feed is connected only to your TV, contact your cable provider.
4. Reconnect the cable to the DVR and try the following, in order. Press the LIVE TV button and check for video after each step.

a. Check the cable connection on the back of the DVR. Make sure the RF cable is securely attached to the CABLE connector.

b. Press the INPUT button on your TV remote control to cycle through the settings. The Input setting must match the physical connection between the DVR and your TV (HDMI or Composite, for example).

c. Press the FORMAT button on the front of the DVR to cycle through the settings. This ensures that the DVR is sending a compatible signal to your TV.

d. If you have any splitters installed, remove them and then reattach the RF cable to the DVR.

5. Restart the DVR. After the DVR restarts press the LIVE TV button. If you still cannot see video, contact the TiVo CableCARD hotline.

Screen blacks out on HD channels


Saying that the problem is with your TV doesn't make any sense since your TV is fed from the cable box.  Your TV doesn't know one channel from the next.  If it had a problem it would effect all channels.  You may not have enough signal to the INPUT of your cable box due to a problem on the pole or at your house or both.  Insufficient signal can cause some digital channels to not get decoded properly by the cable box.  The lower channels will show noise symptoms such as what you describe but they won't crap out altogether like the digital ones.  Have a cable tech come out and measure the signals.

Do you have splitters in line with the cable anywhere?  If there's any way to beef up the amount of signal getting to the cable box try it.
