just wondering

It is very rare for a CRT filament to go open ( burn out ) .During my 45 year career repairing TV s in three countries I only came across three or four at most !! A rough estimate of TVs that I repaired in that time would be around 30,000 !!
Cheers Pete

Yes, the filament can burn out, but only after a VERY long time. I still have a Mitsubishi CRT set that has been used regularly for 23 years and it still looks as good as ever.
A new DLP TV, however, has a lamp that may require replacing in considerably less time than that, depending on how much it's used. But they're much cheaper to replace.

Yes, that is one of the most common reasons that old Cath Ray tubes are obsolete.
CRT Tv is the most researched and developed Tv technology.
The life span and quality have been improved over decades and
is very durable.
