Radiator warm at top, luke warm at bottom

[sealed]

One of my 6 radiators is only warm at the top and lukewarm at the bottom half.
I've bled it (I know that's for cold at the top but thought it was worth a try).

I don't think this is worth flushing for one radiator, as the others are hot. The pipe going up to the TRV is hot. Should I take the radiator off and try to flush out using a hosepipe? Or could it be a faulty TRV?

Any ideas would be much appreciated. Thanks

Try taking the trv head off and make sure the pins out. Is the lockshield valve open enough ? Try that first. If it is, when you take the rad off to flush it open both rad valves into a dish to make sure there's a good flow and return.

Sounds like a balancing issue to me.
Try turning the other rads off, does it get warm now?
