I moved into a house and i noticed that whenever anyone opens the outside door my tv screen goes black and back on couple times. I have laptop connected to tv. Nothing else is affected but the tv. Bought new tv after a while and still same problem. Checked the door but it is just regular door. No alarms or doorbells connected. Anyone has any thoughts?

  • Could opening the door cause vibrations that are affecting the TV power cord? – Barry Dec 29 '17 at 1:46
  • loose wiring in the power outlet maybe. ... put the tv on an extension cord and plug in someplace else. – jsotola Dec 29 '17 at 3:10
  • does the sound cut out or just the picture? – dandavis Dec 29 '17 at 6:17
  • The door opening could jiggle a loose wire in the stab back switches located by the front door that control that outlet. – Paul Logan Dec 29 '17 at 10:38
  • Update: Found the problem. The door, that affects tv, leads to garage. In the garage i have one of those flouresent lights. And that is what affects my tv. Every time anyone opens the door they flick the light switch on and thats why i thought it is the door that messes everything up. Took the starter out of the light and everything went back to normal! – Bematoxylin Apr 9 '18 at 17:14
