Satellite TV providers give you satellite receivers to tune in signals from an orbiting satellite and convert them to programming that you can watch on your television. Receivers, though advanced, are not immune from intermittent technical malfunctions. A basic reset or "flash" procedure is an essential troubleshooting skill for addressing many of these malfunctions. In fact, flashing the receiver is the first step some technical support representatives will have you do no matter the problem. You can do a flash at home without consulting any outside help.
Locate the AC power cable on the back of your satellite receiver. Some receivers' power cables are detachable from the back as well as from the electrical socket. If you have such a receiver, detach the power cable from the back of the receiver. If your receiver's AC power cable doesn't detach from the back of the receiver, however, you will need to trace the power cable into the outlet or surge protector into which it's plugged.
Unplug the AC power cable from the electrical source if you can't detach the cable from the back of the receiver. Look at the front of the receiver to see if the LEDs are illuminated. If the LEDs are off, you have properly disconnected the power.
Plug the power cord back in and allow the receiver time to complete its full boot cycle. If the receiver doesn't respond at first, firmly push in the power cable on both ends and attempt to power the unit on again. Once the receiver completes its boot process, it has been flashed and is ready to be used again.
