What to do if my TechniSat DIGIT ISIO STC has no picture, no sound display on?

If your TechniSat TV Receiver displays no picture and no sound, it might be due to several reasons: * A short circuit in the LNB connection. To resolve this, switch off the receiver, fix the short circuit, and then switch the receiver back on. * A faulty or missing cable connection. Check all cable connections. * A defective LNB. Consider replacing the LNB. * An incorrect external unit installed at the receiver. Correct the setting. * Antenna incorrectly adjusted. Adjust the antenna.
