Living room radiator problem HELP

[Adam c1]

PLEASE HELP
MY living room double radiator gets hot on the back panel of the raditor and only luke warm on the front panel. Also the rad is hot at the top and cold at the bottom. i think this is the last rad in the system but not too sure.
I have already tried the following:
Flushed the radiator last year also ran pipes when rad was off to check flows and all was ok.
Inhibitor added to the system last summer.Magnaclean fitted.
balanced all rads the other day which made a slight difference, not much tho.
inlet flow pipe gets red hot but the outlet pipe barely gets warm.

can anyone suggest anything else before i just buy a new rad??

Any help is greatly appreciated, thank you

Have you tried closing all rads and fully opening the affected rad? If your pump has flow control set it to max. This might clear any blockage. The measures you have taken so far will have done little to clear a blockage in the rad.

I havnt tried this yet, all the rads are on stats, will turning them onto the lowest setting turn the others off enough to do this?? Thanks

You could also try removing the TRV head to eliminate the possibility of a faulty pin/head.

Trv head is already off to check for this, to my knowledge it's not the pin head cos I've done the usual check.... tap wiggle of the pin. Pin is moving freely. Thanks for ur input
