So I am having a strange issue at the moment where the TV reception in my living room has weakened and I am getting interference every time I switch certain lights and fans on (I know that I have two power circuits running through the house). Even more concerning is that the interference also occurs when I open my fridge. By interference I mean that the audio cuts out for a second or two and channels 7 & 2 are dropping out. I have tested to see if it was a power surge issue of some sort and can confirm that no sound drop out occurs If I am watching anything that is not terrestrial TV (ie through my plex server or AppleTV). This has previously happened but has gotten much worse since I completed the following: 1) Installed a HDMI pass through right next to the coax plug - Runs from the back of my PC in the adjoining room to the TV in the living room - THIS HAS SINCE BEEN DISCONNECTED AS I NOTICED THAT IT SERVERLY INTERFERRED WITH MY RECEPTION WHEN EVER THE PC WAS ON AND SENDING A SIGNAL DOWN THE LINE. 2) Installed a coax point in my study and used a splitter to run both the living room and study points - THIS HAS ALSO SINCE BEEN REMOVED SINCE I NOTICED THAT THE SIGNAL STRENGTH WASNT HOLDING CHANNELS 7 & 2. Even after reverting back to original setup, the reception is still worse then before. Other trouble shooting I have completed: 1) Replace the coax wall mount - The old one was looking a little worn. 2) Replaced the coax lead running from the wall to the TV. 3) Cleaned the coax copper cable to try and get a better connection with the wall plate. 4) Tried a signal booster from Bunnings with no luck. Any ideas???
