I'm no electrician so perhaps you should get conformation first.
You should have a switched live going to light (normally labeled to say it is switched live.) This could be blue or brown (depending on how it was wired) so not all blues go together and browns if you understand what I mean. One is your switch live.
Sounds like you have some wires crossed. In case of living room switched live and permanent live crossed over. In the case of the kitchen something similar but the switched live is not properly postioned at all. Note that the permanent live goes to the switch in each case via the red (or brown) wire and come back to the fitting via the black (or blue) wire. The black (or blue) wire from the switch should be sleeved red (or brown) to show that it provides the live feed to operate the light.
Did you take a note of what wires went where and label them when you disconnected the lights? Did you ensure they went back into the right connectors when you reconnected?
Have a look at the projects section where you will find details of how to wire ceiling lights. Without actually seeing the problem it's difficult to be more help.
You could try to paint a word picture of what wires are currently connected to where which might help.
It is common for the DIY enthusiast to make errors when changing light fittings. As a result I have made this standard reply I am tired of saying the same thing over and over again. What seems the problem is they don't expect the light to be feed with two wires the same colour (although one may have a bit of tape or sleeving on) neither do they expect the wires coloured in the Line (Phase) colour not to go to the lamp. Once they realise their mistake connecting earths (Green/yellow or bare) and permanent Lines (Red or Brown) together is not a problem but then they have three wires (Black or Blue) of which two are neutral and one is switched line. With luck the tape or sleeving is still on the switch line but if not there is a problem. Leaving one wire disconnected and trial and error finding the live and neutral pair is not to hard then the remaining wire needs pairing with one of the other two. Again trial and error will work as if connected to wrong on the next light in chain will not work correctly.
So to recap on the black or blue wires first mark each wire so you don't get them mixed up again. Bits of tape or correction fluid lets call them 1, 2, and 3. Connect 1 and 2 to lamp if it works great if not try 1 and 3 if it works great if not try 2 and 3. This leaves one wire over I will call it A and the connected wires B and C. So to get next lamp working try A with B if works great if not try A with C.
If there are any extra wires tough call in an electrician this often happens in bathrooms where there is also a fan connected if only two then great does not matter if the two blacks or blues are wrong way around it will still work.
If it still did not work call an electrician I have covered the common way if it has not been followed then tough sorry. Remember to turn off electric between each test and at the mains the switch on the wall will not isolate the ceiling rose. Also looking at projects can also help and taking photos is a good idea before starting any job so if you do miss marking a wire you do stand some chance of working out where it went.
All best Eric
