my screen has narrowed to the centre of tv goodmans matrix?

Sounds like both tv's would have vertical problems . Why both tv's went out at the same time is odd but some sets do have certain patterns . Sounds like you might have some capitors that have dried out causing your picture to start collapsing. This is common in alot of tvs . Your tubes should be ok as long as the color and brightness have not changed over the years as this would indicate a weak or bad tube . call your local repair shop to see what an estimate would cost or a ballpark figure to fix the set would be . My shop would charge around $40 to $75 depending on the parts it would need . Hope you can get it done cheap , Good luck
