T.V. Reception Problem.

Morning all on this chilly breezy morning


I installed a new t.v. aerial outside on Friday for a couple that has just moved house. I could not get their t.v. to self tune on the freeview channels. The screen has just frozen and does not shown a self tuning progress bar, and just displays an error message asking me to wait for new channels to be found. It makes not progress at all. It is just frozen. A second t.v. of theirs does show signs of life as it tries to auto-seek new freeview channels. I had to leave at that point as the lady of the house was exhausted after her move and needed a quiet lie down.


Is there a method of re-booting the first t.v. to work, or is the tuning circuit faulty?


The new bungalow is located right next to a new supply transformer an the new estate is only 50 per cent occupied. I wondered if the higher Voltage may have possibly damaged the t.v's circuits boards.


Any help much appreciated.


Thanks,

  • My first suspicion would be the UHF signal I'm afraid - the slightest error in making off the terminations on a co-ax (e.g. a single strand of the screen touching something connected to the centre conductor) can completely kill the signal to the TV. In the old analogue days getting the wrong 'band' of aerial for the local area could be almost as catastrophic (but I think most are wideband these days to cover the digital range) - as can getting the wrong polarization (vertical or horizontal) for the local transmitter. Given the problems with two sets, I'd suspect the common element (the aerial setup) first.
