Big problem Sora Gear derailleurs or flightdeck shifters

Hi all, just bought used Ridgeback horizon triple for getting back into road biking after afew years and cos the old git finds it difficult to get up off road ascents these days!
Bought off guy who is disappearing abroad at road side meet. At the handover I found that the rear derailleur did not change from 3rd sprocket even though shifter clicked for both up and down movement, the front set shifted upwards so thought was ok.
Got back home cleaned it and found that the lthe front derailleur won't move back down and the shifter is stuck and won't click anywhere up or down. Before I start dismantling anything, can anyoine advise what the prob may be and any remedy please. I have never used this type of shifter before as my old Sun Solo of 1979 vintage is unindexed and shifters are on the down tube!. Unfortunately I was under time pressure to get back for an important meeting 20 miles away otherwise I woulkd have looked at it more closely, but i did get a reduction in price!!. Thanks , Phil

Have a look on the Shimano website, Park Tools, or Sheldon Brown for step by step guides to setting up from scratch.
If you do conclude something's broken, I hope it's the cables (cheapest) or mechs (next cheapest) rather than the shifters. If the shifters, Ebay could be your friend
