How can I fix my 15" Wharfedale HDTV/DVD Combi?

Basically what happened was my TV fell of my unit the drop was no higher than 1m. I try turning it on the screen blips and nothing shows up however the sound and everything still seems to work! It's got warranty for 1 year yet only problem is I don't have the remote for the tv anymore. Any help would be much appreciated as this is really annoying..
