Hot radiator top cold bottom

I have a large bay radiator which is hot at the top but cold at the bottom.All other rads are OK & hot water is OK.
Try temporarily turning off some of the other hottest radiators. If afterwards, the radiator gets fully warm, then the problem is the system needs balancing.
Check the DIY projects section of this website for information about how to balance a heating system.
