There are a couple that I can think of that you may be able to try.
However 1 or 2 of them are organisations
Independant Services - 08450 508570
Cutchey Repairs - 02380 470171
Don't be put off by the codes
They as far as I know are the head office numbers
They will have an engineer in your area
Also don't forget that if it is still within 2 years of when you bought it you can go to Samsung as it is still within warranty
