In Monitor CRT Red-Blue-green cathode guns are there.. Mixing of these colour we can get the original colour chrominace technique. if any of the colour gun is faulty we would get more REad or blue or green picture. Measure RGB voltages. you can verfify which gun is faulty. if then check RGB processing circuits. Else there might be problem Chrominance colour decoder system. Contact service centre

My screen have some red lines

I will assume from you description that this is a rear projection crt(picture tube) tv. if this is true I have good news/bad news.
faint red horizontal bowed lines in the picture indicate the screen(G2) voltage for the red tube is too high.Slight lowering of the G2 adjustment will eliminate these lines. I stress SLIGHT because too much adjustment will mess up the gray scale .
The bad news the red crt made be bad. if the adjustment works but in the future the problem reappears then suspect the red crt replacement is probably not economical to repair.
