The tv has sound but no picture. For

For the last couple of weeks it has been doing strange things such as the Dish remote would not turn it on or off or it would not show the menu. I thought it was the remote, however today, the picture went out.

I have a foxstat -HDR humax box and I am getting no or bad signal on the TV downstairs. I can get some channels but not all.


I suspect that the box upstairs is a Freesat box; a Freeview box requires a feed from an aerial, not a dish.

The problem you are seeing may be caused by water in the cables, if they are not sealed at the LNB. The LNB may be failing, but dish misalignment is more likely.

As there is an unused output on the LNB, try swapping one of the feeds with a poor signal to it.

Dish remote 2 changes channels on both tvs and dish remote 1 changes channels on both tvs


Is the receiver in dual mode? Go to the receiver, open the door, and hit the mode key. If both TVs are still showing the same thing, then the issue is not the mode.

Go to TV 2 (the one without the receiver) and make sure the TV is tuned to channel 60 or 73. If it is still showing the same thing, go to TV1 (the one with the receiver) and hit Menu, system setup, Installation, modulation (menu 6-1-5). make sure the modulation for tv2 matches which channel you put your tv2 on.

Still showing the same thing? check the back of the receiver, the RCA cables (red/white/yellow) are plugged into the TV1 ports not the TV2 ports.

Showing different things but the remote still changes channels on both tvs? Go to TV1, hit menu twice, near the bottom there are two boxes each with a number. This is the address for each remote (tv1 and tv2). On the TV2 remote hold sat until it stays lit, choose a number different than on the screen, touch pound (#), the sat light blinks three times, hit record, the number on the screen should change to match the one you typed in.

Still being silly? Call a priest, you have a poltergeist!

Hello, my name is Becki Barned with Dish Network customer service. I understand the frustration with this issue. There are a few things that could be causing this problem. There could be interference with a remote at a location near yours, such as a neighbor's remote. It could be a grounding issue, in which case a technician would be needed. Since it is happening on the second unit, a technician may be the best resolution, because as I said, it may be a grounding issue causing this. If this has not yet been resolved, or you have any other questions/comments, blog back, or you can also find us on Twitter!

Hi my nameis Mike Houston of DISH Network and I see when you try to change the channel itskips some. There are a couple of things you can check to make sure allchannels are showing. Please press the Menu button on the DISH Network remoteand on the top left it will say All and you want it to say All Channels, then youwill want to make sure all the channels in you're Programming Package arethere. If they still are not showing please unplug the receiver for 10 secondsand after plugging it back in it will power up and acquire the signal anddownload the Program Guide, you will then want to make sure all channels areshowing. If you have any questions or concerns please e-mail me at [email protected]

DISH Model 625 skips to the end


Hi claramarie20there are a couple of things to look at when this happens. The first thing youwill want to do is replace the batteries in the remote, after you replace thebatteries you will need to press the MENU button and the numbers of 6-1-1. Itwill take you to the Point Dish screen and from there please select the CheckSwitch tab and then the Test button. After the test completes exit out of allmenus and the receiver will reboot and acquire the signal and it will stop the receiverfrom powering on and off.

Red and Yellow blurred picture


I had the same problem this week. I tried the convergence thing but it was impossible to fix. I still needed the repairman. He changed two convergence units ($325, parts and labor). Then the tv was still doing the same thing. We had to adjust the convergence and now everything is perfect. You will need your converter

most likely there is a button on the remote that is stuck on. try moving all the buttons to see if they "feel" stuck. if not then take the remote apart and clean the contact pad bottoms and the surface of the board with rubbing alchohol. good luck!

Problem with sanyo tv


Check the menus in the TV. Look for a Display menu. There should be an option somewhere to turn this off. I don't know this TV personally, but it CAN be turned off.
