I have a 4 year old Sony CRT TV. Recently it began having lines across the top of the screen when first turned on. At first the lines would go away after an extended warmup -- they've quit going away. For about the last 20 years I've quit getting TVs repaired. It usually costs about half or more as much as a new TV and after it's fixed you have an old TV. But, the set still has a good picture, so after only four years, if this is an easy thing to fix I figured I might give it a try. So, will this probably be an easy (read cheap) fix?
Here are pictures that illustrate the problem:
