try turning all the rads off then turn heating up and just turn the 2 in the living room on and see what happens

I would recomend a flush, once that has been done balance your rads, turn them all off, the ones that do not get much heat at the moment, turn them on slow. Once you have them nice and warm, turn the others on slow, until heat comes through. This should do the job. I assume this problem has only just started.

The system needs a flush or most likely the radiators need balancing.
