Replace paper caps in TVs with film caps if a sufficiently close modern film caps value exists.
You can get some spooky issues and strange drift from ceramics doing a film caps job.

What Tom said ^^ it's important. And in audio circuits, I know that many disc caps were used. But if I need to replace them due to damage etc., I use film in HiFi amplifiers because at high frequencies, the Piezo effect "may" affect the frequency response. Film caps are inexpensive.
In TV sweep circuits, it's probably important to go type for type. I don't try to second guess the engineers, even though they were often badgered by the bean counters
