Lifetime of 9pg Plus CRT's

Since the hours can easely be reset, you need to look at the tube faces themselves to judge.


The general figure is 10,000 hours on average. Depending on how hard they are driven contrast wise, they can go 1000 to 25,000. I have had a projector with over 32,000 hours on the tubes, and it still made a decent, though soft image. I have also had units with less than a 1000 hours that were burned so bad they were useless for video.

NEC's problem is that the owner's manual told you to install the set too far away, so you'd use a smaller raster area, causing premature wear. It wasn't that the image was all too bad within the wear area, it would just be annoying to view the brighter image around the wear area when the set was set up properly, so if that's the case with your unit, you might have to retube...


Properly set up, you should get the full 10 K hours out of the tubes.
