Hi,
My Philips 32 inch TV (old big box style which I think is CRT

) in the last week or so has developed an intermitent green tint on the screen.
This green tint sort of comes and goes when I'm watching analogue TV, Teletext or playing my XBOX 360 (3 leads into a scart connector).
Bemusingly when I watch DVDs I've yet to see the green tint.
Any of you experts come across this?
It's been suggested to me that my "tube" is dying a slow and painful death - which I could understand but the DVD angle is throwing me....
I've tried to ask Philips direct for help - but not getting anywhere fast with their customer 'support'....
Any advice please??
If my TV is going to die I'd like to replace it sooner rather than later - or could this fault be something else?
Sincere thanks for any advice or thoughts,
Duder
