If you have all 3 tv's in the one house and on the one antenna then it sounds like you have been subject to either a lightning strike or a large static discharge onto your antenna. What this means is that the tuner packs in the back of the tv's has been damaged and will need to be replaced. However as you have said in your question they do work using an av input. This will be your cheapest option to get them working again. Buy cheap vcr's for them and connect via av cables, as the tuner modules are expensive to buy and even more so to have fitted.
