Question about a Phillips 50

Hello... I'm a troubleshooting trainer for in a contact center in Florida. I'm hoping to get some help with a television that we are having issues with.

I've been told that there is an issue with contaminated coolant in one of the picture tubes, specifically, the blue one. This was confirmed when I looked at the tube and say the spotted haxy look on it.

In reference to the technician...it was suggested that a qualifed tech would need to look at the issue. I'm learning by experience in my new postion, so any help would really be appreciated. I need to know if it's just the picture tubes that would need to be ordered or if there is another solution for this. The TV in question belongs to a customer that purchased it in '01. I have all the info for the TV if/when you need it.

Thanks a whole bunches!
