The high voltage is needed for the color tube to function. The current consumption is about 300uA/ cathode, so 3x300uA≈1mA. The power needed: 25kV x 1mA=25W, at maximum when the image is intense white.
Don't try to measure this yourself -- it' quite dangerous with conventional multimeters. The values are from tube specifications.
