Although I have bled it, no air escaped. I turned the valves on the bottom of the radiator the other day and now don't know which direction they should face as one valve is hot but the radiator and other valve on the opposite side is cool.

[Edited info] thanks for the answers. Water came out of the radiator but no, I haven't bled it fully to see if there is a blockages somewhere.
By the way, the valves are flat-shaped which I turned with a pair of pliers. I presumed that if I fully turned them anti-clockwise they would be 'open' and if turned fully clockwise they would be 'closed'

ok, i have bled the rad but nothing adverse came out, just jugs of clear water. both valves are fully turned anticlockwise to the open position and still no heat. the rad in my computer room usually blocks but that is running hot so any other ideas?

You say no air escaped, but did any water come out? the system may need balanced, which means adjusting the lockshield valves (at the opposite end from the thermostatic valve), close them slightly to force more hot water to the cooler radiator, I suspect this cool one may be the furthest from the boiler?? One valve is hot because that is the flow end (Hot water in) the other end should be hot as the still hot water passes out to the return and back to the boiler for re-heating.
If this does not help you may have a crushed pipe or a radiator blocked with sludge/magnetite.

Turn valves fully anticlockwise for on and fully clockwise for off. Balancing the system is theoretically fine but seldom needs to be done. It involves measuring the temperature of the hot water entering and leaving the radiator which is not that accurate. Good luck

Right is off, Left Is open, Unless the valve is a lever style, Then you put that valve handle so It runs parallel to the water pipe,
Re burp It, If nothing is coming out when you bleed It, That's because Its empty, Also make sure the valve your bleeding is not clogged

If you have bled the rad properly and its still cold, I would suggest removing the rad altogether and flush it through. It could be that the rad is full of 'sludge' thats built up over years. I had the same problem with a rad furthest from the pump and yes it was full of sludge. If your not 'handy' with plumbing, I would suggest you get a plumber to do this job.

Try bleeding the whole system as the air could be trapped in the pipe leading to the radiator.Do you have thermostatic valves on your rads.
If so you would need to call in the pro's

bleed the radiator - drain the water through to check no air inside it! Air stops the hot water from warming up ur radiator

have you already bled the system as well as the radiator. sometimes you have to do it a couple of times to expel all the air

Have you got a radiator key as it might need 'bleeding' HTH
