That's why they do it, to make you buy a new TV. Same with most "consumer electronics" these days. At one time, you could take stuff that wasn't working to a little guy in a brown coat in a back-street workshop and he'd fix it for a reasonable charge. Now it's throw it away and buy a new one. No joke when TV's can now cost anything up to £6000 for the top end models. Not that ours were that much, but they were still around £350-£400 each.
