Outdoor network cables or power cables are routed overhead.
A switch is deployed outdoors but is not properly grounded.
Damages of Lightning Strikes
If power cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn the power supplies.
If network cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn interfaces of the switch.
When a switch undergoes lightning strikes, overvoltage is induced by lightning on network cables and transmitted to interior of the chassis. The surge protection measures, such as lightning rod and chassis grounding cannot prevent the damage. Therefore, surge protectors or surge protection circuits are recommended.
Surge Protector Use Precautions
Take the following precautions to protect a switch from lightning:
Ensure that the ground cable is connected to a ground bar or a ground point on the cabinet.
Avoid routing cables overhead in an outdoor environment. Bury cables underground or route them in steel tubes.
To protect network interfaces against lightning, use 8-line surge protectors (or Huawei certified 4-line surge protectors).
When installing a network interface surge protector, connect the IN end to terminals and the OUT end to network interfaces of the switch.
If a fixed switch is installed in a network box, follow these instructions:
Connect the ground cables of the switch and surge protectors to the ground bar in the network box.
The maximum length of a ground cable cannot exceed 40 cm, and a length of smaller than 15 cm is recommended.
If the network box is located outdoors and power cables are routed aerially over a long distance (more than 300 m) to the network box, it is recommended that you install a power supply surge protector in the network box. The decoupled power cable must be at least 3 m long
1.is the tv plugged in & getting electric? 2. Does the tv show a raster,a blue screen. 3.is the tv getting an input signal , assuming that the answer to 1 &2 was yes. 4. Is your cable box plugged in. 5. are all the connections into your cable box connected or did one fall of 6. did you pay your cable bill on time. If your cable box is bad , the cable company should fix or replace it for free. If you or someone else unhooked the connections,say by tripping over them,the cable company will restore the connections and chatge you a service call fee. 7. do you have dish or direct tv? either of those services will loose picture if it is raining out and picture wont come back until after the storm passes. 8. if you have dish or direct tv, and a branch,a person or an animal, a bird, has fallen on the dish/direct tv antenna, it may have misalligned the dish and it will no longer recieve the satalite signal. THere is a reallignment service available;dish network charges $95.00 unelse you have insurance,like i do,so it only cost me $15.00 I never had direct tv soi could not say, but dish net claims direct tv is more expensive
You can allign the antenna yourself ,if it is not on a steep roof. You need one person moving the antenna & another person at the tv telling him if the picture is getting better or worse. The dish box comes with a built in signal strength gague for that purpose.
enjoy considering these options and they next time you ask please enclose all the information that you can so that we have something to go on and work with.

If you can monitor the supply to the LNB, you may find it is low, unplugging it when the decoder is powered up allows for more power. I would change the power supply capacitors if more than a couple of years old.
Hello, this is Becki Barned, with DISH Network customer service. For this issue, since you have already replaced the remote and have the 5 foot coax cable on the antenna, then at this point, we would want to send a tech out for you. The technician can determine if this is an issue with the receiver box, or can set up a back feed for you. I can help you out with this issue further. You can e-mail me at email@example.com .
Do you have an antenna hooked up? You'll need one hooked to your converter box because the digital signal is so much more difficult to tune in to. This may help:
If you live closer than 15 miles, rabbit ears
If you live closer than 20 miles, omnidirectional
If you live closer than 50 miles, midrange outdoor (oldschool arial w/ rotator)
Further than 80 miles, you'll need a long range with rotator, perhaps
even an amplifier to go with it. Print off what your results were on
antenna web and bring it to a RadioShack or a local antenna store and
they should be able to point you to the right antenna for your
using your Dish Network box connect the audio and video outputs to the tv via the RCA inputs1, 2, 3, or component inputs on the tv and then select the coresponding video input to view your cable. Or you can connect your Sattelite to the antenna A or B input jack on the back of the set and set the tv input to antenna
THE BEST INPUT ON YOUR SET IS THE HDMI INPUT.2ND THE COMPOSITE INPUT. 3RD THE COMPONENT INPUT. AND 4TH THE ANTENNA INPUT. MOST DISH BOXES HAVE AT LEAST THE COMPONENT OUTPUT. YELLOW IS THE VIDEO AND RED AND WHITE FOR AUDIO. USE RCA CABLES TO GO FROM BOX TO LCD SET. ON THE DISH BOX YOU CAN GO FROM ANTENNA OUT TO THE CABLE OR ANTENNA IN ON THE LCD. SWITCH TV TO CHANNEL 3. AND TURN YOUR DISH BOX ON.
