hi there!!


I wondering about my green tube on my 1209 ,the 1209 have

gone in 13000 hours .and the red and blue tube looks nice

but the green tube have a very brown square !

so my question is how much better will the picture be if I change the

green tube to a new one ,or change the phosphorus?

the picture is very good in blue pictures but in green Its not so good.

and the focus is very hard to set on the green.


I hope you can give me some answer..


kind regards

You will see a noticeable difference. The green focus will improve and the colors will also go back to normal. It is very standard for high light output sets to have the green wear out first.


Go for it, you won't regret it!

Can there be a problem having a PJ with a new green tube but old red/blue tubes? If the PJ has been running for enough hours to wear out the green tube, isn't the blue and red tubes worn too even if they don't show any visible wear?


What I'm trying to say here is would there not be an "inbalance" in the picture with a brand new green tube and tired red/blue tubes?

In order to get the R & B tubes to balance and produce D65 white, you will have to adjust the "gain" on the B $ R higher than they are currently set to offset the brightness of the new G CRT. Should be adjustable, and very bright!!
