Radiator cold -previous on system hot

[Maggie Mac]

I have a flat with an 18 month old combi boiler and 6 radiators . The system was power flushed when the boiler was installed. Everything was fine until recently but now one of the radiators isn't working. The living room radiator is hot but the one it feeds (in a bedroom) is cold. The pipe is hot as it leaves the living room radiator but part way along it becomes cold, so the bedroom radiator is cold. I've tried bleeding the radiators and checked the valve on the cold radiator, which seems OK.

Any ideas ?
