Question about Televison & Video
I removed the back cover and carefully vacummed as much dust off as I could, as suggested may be the problem. This made no difference. Is there something else I can do myself/
You don't mention the model, but your symptom is common for many brands of TV. Solder connections inside the tuner go bad and cause the kind of problem you are having.
When the trouble starts, try tapping on the back of the set where the antenna or cable connection is screwed on. You may find this causes it to clear up or at least have some effect. If so, the problem most likely would be cured by repairing the tuner. This involves taking the tuner off the circuit board, opening its cover, and resoldering the connections that are usually visibly cracked.
This is probably not a repair you could make yourself, unless you have some experience with electronic soldering. But a service call would be less than the cost of a new TV. If you decide to go with a service call, make sure to tell the servicer you'd like the tuner repaired. Some techs will just give an estimate for replacing the tuner because of time, but opening and repairing the tuner does not take that much longer than just replacing it. And it saves you the cost of an expensive part.
