Have 1 downstairs radiator which is cold at bottom. If I turn off other radiators downstairs then it gets hot all over but reverts to cold at bottom when others are turned back on. I have tried it with other radiators gagged right back but then only gets a bit warmer at the bottom. Any help appreciated.

Its either a flow problem from poor balancing or its a sludge problem
Is the lockshield valve fully open? (thats the end you dont normally touch by the way)

Could be that one of the pipes leading to it is kinked or restricted by debris as well.
What system do you have and what speed is your pump set to?

try bleeding them when switched off !!
What on earth does bleeding radiators have to do with the problem described? The rad is hot at the top, so hot water is clearly getting to the top of the rad, so no air there.
in my experiance its usually a build up of sludge in bott of rad
