I am experiencing sporadic pixellation on all HD channels from the Dovertransmitter (Channel 53). The TV set is under one year old and reception is shown as 100% signal, 100% quality. It was excellent until about late October/early November. Early this year I purchased a Freeview Play recorder and discovered that the HD pictures from this box are perfect, both live and recorded despite the aerial lead being longer and of lower quality to the one to the TV. The aerial is a loft mounted electronic device, the downlead is inside the building feeding through a surge protector, a VHF/UHF splitter, and a 4 way distribution amplifier.
Among other resets and trials I have fitted an attenuator to the TV lead in case signal is too high, I have tried fitting a G4 filter in the feed before the splitter, I have retuned several times and manually tuned the HD channel, I have swapped the feeds from the amplifier, and I have fitted a new spike/surge filter to the mains feed. All to no avail. The software on the TV is up-to-date.
In view of the fact that there are no problems with the Freeview Recorder it would seem that the TV is faulty. Is there anything else I can do to prove it?
