Weird TV Problem

[Danger Phoenix]

I am having a weird problem with a 11 wear old Phillips TV... for some reason the colour on the screen is all green. I have checked all inputs and tried various input devices, but I think it is the TV. A friend said it could be the colour tubes, but I thought there was just one big vacuum tube

I've had that problem many years ago with an old TV, it was one of the tubes. But fortunately it had warranty and the tube was replaced.

Not much you can do really.

Oh right

Do you have any idea how much they cost?
