Question about Vizio Televison & Video
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

While you have sound, take a flashlight and shine it on the screen, look very close and see if you can see a dark video image.

SOURCE: Tv has sound but no picture.
If it works on DVD but not on your Dish, and when you connected it to another house it had the same problem then it sounds like your input connection is bad on the TV. That is if I am understanding this right. From what I am reading your Dish network is not showing a picture but the audio is working fine. The DVD player works fine on the TV though. Then you took the TV and hooked it to another dish system and it was the same problem. That sounds to me like you TV is having a problem, either that or the cables for your Dish network are bad. Try switching to a different input, like the one the DVD player is on and seeing if it works there. If not, then the cables are bad and you just need to replace the cables. If it does work though where the DVD was working before then your TV input is bad on that port you were hooked to before.
Let me know if you have any other questions and if this was helpful. If you need some more clarification let me know, I hope this is helpful. Good luck and have a good weekend. Get it fixed before the Super Bowl.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

Hello. This is usually an easy issue to fix. To get the DISH Network back on the screen, i have included a few steps:
If you are at TV1, where the receiver box is located, the tv needs to be on channel 3 or 4. Depending on the cable that is running between the receiver and the tv, the tv may need to be on an input, such as video 1 or 2. If you are at the TV2 location, where there is no receiver, then the tv needs to be on channel 60 or 73.
If you are using an HDMI cable, then the TV will need to be on an HDMI input
If you are using Component cables, your TV will need to be on a component input. (Usually Comp 1 or 2)
If you are using RCA cables, then the TV will need to be on a VIDEO input (Usually Video 1 or 2)
If you are using COAX cables, then the tv needs to be on channel 3 or 4 (If you are at TV2, then the TV needs to be on channel 60 or 73)
