I`ll start by saying that there are not one but 3 tubes in there and yes they are monochrome but red/green and blue .In any case this is far from certain that the tubes would be the problem and as a matter of fact I would be totally surprised if that was the case .Right now you either have a power supply or high voltage/deflection circuit problem not to mention a very possible vertical or convergence problem .Lets not forget the control and protection circuit as well if it is in shutdown or perhaps simply a video circuit problemDoes the light blink at the front ?
