Troubleshooting FAQ

1. I have no dial tone or hear static over the dial tone. How do you determine where the problem is? Locate the Telephone Network Interface on the outside of your home, usually located next to the power meter. Use a screwdriver to open the interface. You will find a phone jack inside, unplug the cord that is currently plugged into the phone jack. Using a corded telephone plug it into this phone jack. If you do not have dial tone or you hear the static while plugged into the interface then you should notify Nsight that you have no dial tone at the interface or noise at the interface. If you do not have any problems with the dial tone at the interface then that would mean there is a problem with some wiring or a phone in the house.

2. I have no Internet. What do I do? Do you have multiple computers? If yes, check the other computer to see if the internet is working. If it is working then you have a problem with your computer. I would try to restart the computer and if you still can’t get online you should give a call to Nsight at 920-617-7050. If the other computer also cannot get online, then locate your modem and power it off for at least 1 minute. The modem is a device that brings in the internet service over the phone line and is usually located near one of the computers.

3. There is a problem with the telephone wiring or possibly a phone in my house. What do I do? First start by unplugging all devices (phones, fax machines and modems) from the phone jack. Check each phone jack with a corded telephone to see if you still have the problem. This should narrow down the problem. If all phone jacks work properly (you have dial tone or there is no static) then one of your devices (phone, fax or modem) is causing the problem. Plug in each device one at a time to find which one is causing the trouble.

4. What if I have only one computer and I can’t get online? You would then want to locate the modem and power it off for 1 minute. When you power it back on, it will take a couple of minutes for the modem to reconnect. After powering off the modem and you still can’t get online then try restarting your computer. If that doesn’t help please give Nsight a call at 920-617-7050.

5. What is Aspect Ratio? An aspect ratio is the ratio of the width to the height of the TV screen. The aspect ratios differ because the television industry manufactures both standard-screen and wide-screen HDTVs to appeal to consumer viewing preferences.

6. What is Digital Television? Digital television (DTV) is a huge leap forward in the television technology compared to analog television that has been widely available since the 1940s. DTV is delivered and displayed using digital encoding similar to the way a PC operates. By using digital technology, there is no variation in picture and sound quality from the origination point until it is displayed on your television. You always receive a high-quality picture without the wavy lines or static you might sometimes get from a weak analog signal. Some service providers offer on-screen channel information, and other various guide data. Another feature of digital television is digital surround using digital technology, which is the same technology used to produce the sound you hear in movie theaters.

7. What is High-Definition Television? High-definition television (HDTV) is a completely new way to send and receive television broadcast signals. HDTV images are made up of pixels that are much smaller and closer together than those used in standard analog television, and there are millions of them. Thus, HDTV can display five to six times the detail of analog television to deliver picture quality that is much more realistic, dimensional, and precise. SDTV programs can be viewed on an HDTV.

8. What is Standard-Definition Television? Standard-definition television (SDTV) is basic digital television programming delivered by your service provider. Typically, the SDTV screen is the same, nearly square shape as an analog television screen. Digital images on an SDTV set are crisp and clear – noticeably than on a standard analog television set using an antenna to receive over-the-air signals.

9. What is the Difference Between a Standard-Screen and a Wide-Screen HDTV? The type of screen your HDTV has (wide-screen or standard-screen) determines how the receiver displays programs on the screen. The picture format for an HDTV is a combination of aspect ratio and screen resolution and is different for standard-screen and wide-screen HDTVs.

10. What is the Screen Resolution? The screen resolution indicates the amount of detail that the picture displays. Resolution is identified by the number of display lines on the screen. The techniques that an HDTV uses to “paint”the picture on the screen are referred to as progressive and interlaced. With the progressive scanning method, the lines are drawn on the screen one at a time in a sequential order. Progressive scanning results in a more detailed image on the screen and is also less susceptible to the flicker commonly associated with interlaced scanning. The interlaced method involves refreshing pixels in alternation – first the odd lines and then the even lines. A standard-screen has a 4×3 aspect ratio. The screen is 4 units wide for every 3 units tall. A wide-screen HDTV is one-third wider than a standard-screen HDTV. The Screen is 16 units wide for every 9 units tall.

11. Why Are Some HDTVs 4:3 Aspect Ratio and Others 16:9? The aspect ratios differ because television manufacturers build both standard-screen and wide-screen HDTVs to appeal to consumer viewing preferences. The two aspect ratios are as follows: On wide-screen (16:9) HDTVs, the programming is displayed on the full screen. On standard-screen (4:3) HDTVs, the programming is displayed in letterbox format in the middle of the screen. There are bars surrounding the picture.

12. Why Aren’t All the Shows I Watch in High-Definition? A high-definition program must originate in HD format and be broadcast in HD format. Having an HDTV system does not mean that everything you watch will be viewed in high-definition. Getting the signal from a digital source also does not mean it is high-definition.
