We have a technika televison in the bedoom, when we switch it on, it knocks my sons tv out and he can't watch anything. We unplugged the aerial in our room (even though they are both on seperate aerials) and just switched the tv on and it still knocked his out, so it's nothing to do with the aerial anyone have any ideas thanks
You are a legend. After trying out different things, over several months, finally something that works. We took advice from the Radio and telly forum and numerous others, but nothing worked. Just tried a spare surge protector, and, 100% success. Thank you very much. No more moaning from the kids when we turn our telly on. Thanks once again.
Definitely go with Woolwell on this one, get your electricity circuits checked out.
A neighbour asked me to install an alarm system early this year. Using power tools around the house, we eventually tried to use a socket in one of the bedrooms. The power tools wouldn't, but the tv, bedside lights etc did. We found that the socket had been wrongly wired up, and had been like this for a number of years.
When we moved into our present hose some years ago, we were told it had recently been rewired.
My stepson, a fully qualified professional electrician, decided to check it out. He found a basic error in that the incoming current had been wired in reverse. He quickly corrected this, but said they had left it in a dangerous state.
As I've interpreted the situation the son's tv is having it's rf signal corrupted by interference from the switch mode power supply in the Technika tv. Fitting a surge protector (which invariably include a suppression network) reduces mains borne interference which is conducted or (more likely) reradiated by the mains wiring. There are suppression components fitted inside tvs to reduce this but they may have failed or the son's tv aerial has defective shielding.
