cold rad

[diggerman476]

Hi,
I have one cold radiator in an upstairs room.The thermostat valve is working and the pin is free and depresses fully,the hot water feed pipe is hot.Only one small corner of this double rad is warm. I have turned other rads off trying to pressurise it but this does nothing.I have tried to bleed it but there is no air in it and I have tried to just bleed the water through it until it becomes hot but still nothing.
ANy tips or suggestions would be gratefully recieved!!
Thanks
Adrian
