Turn off all radiators in the house EXCEPT the faulty one, that generally does the trick, There may be an air lock somewhere. Let it run for 5 minutes to blast out the air.
You can open all the valves again. Make certain that there is sufficient water in the header tank, and it is also a good idea to get FERNOX as an anit-corrosion liquid into the system.
If it does'nt work email me.

Sounds like a circulation problem, you may be airlocked somewhere in the piping ahead of where that radiator is. Try bleeing all the radiators in the circuit and see where the last one that is in that circuit is located. This is more common in convection circulation (no pumps) because of debis that builds up in the pipes and slows circulation over the years. You might try installing an auto bleed to alleviate the problem. Systems that do not have auto fill, also loose pressure if there are any leaks in the system, and if you bedroom is furthest away on the run, or on a second story, it takes a while before the radiator will heat. If your system maintains good pressure there is a pretty good chance you may have to do some repiping. Also make sure that any valves in the line are fully open.

Perhaps the radiators need balancing meaning that more water pressure goes to the upstairs radiators.To do this screw down the hexagon fitting usually on the left side a little trial and error.Could also be a water pump fault try and turn this up to its maximum setting.Their are numerous reasons for the fault its all a question of trial and error.

Couple of potential solutions: there may be sludge in the bottom of the radiator in which case you either need to take the rad off and flush it through or put some fernox in the system, otherwise the trv could be sticking and not letting the hot water pass through, in this case you'd need to loosen the pin inside the trv. Try not the flood the place tho, Good luck!

Completly drain the system and fill it again. make sure you bleeder valves are working, You can buy bad ones from the hardware. just return it and ask for a new one. It Happens.

the pressure could be down -check pressure gauge at boiler point & re-adjust if pressure showing low
