Single radiator not getting hot at all

I've had a couple of rooms which have had the rads turned off for over a year, as i dont use them.

I've turned one of them back on, and it's not getting hot whatsoever.

At first i thought i'd unbalanced the system, but i've turned off all the rads now except that one, and it's still totally cold. The pipework going into the TVR is warm up until about 10cm before it reaches the TVR valve.

This seems like a blockage in the rad itself.

Any thoughts?

TRV pin stuck in the body probably
