My bedroom TV reception is great up to about channel 16 after that the reception is unwatchable,its been good for many years and the aerial is in the loft. I have checked the co-ax cable connection which is good. Appreciate any ideas on what the problem might be.
what i have done in the past is remove coax cable from box then let it retune, sounds odd but it works, let it find nothing, then reinsert cable and then retune.
