Due to the lack of information, I'll make some guess.
From the age, I will assume this is a CRT TV
If the blue screen is normal in brightness and is lacking Red and Green, then the Red and Green guns of the CRT are weak.
The first step is to check the CRT using a proper CRT tester to check the condition of each color gun.
You can also check the signal to each gun on the CRT driver board (neck board) to see if the signal levels appear normal. If you don't know what normal looks like, then compare all three and they should be similar.
