Basically with solid state electronics, you either accept the defect or return the telly if it's still in the warranty period, or replace the whole device.
thanks for the reply, my TV is a Sanyo I've been doing some reading online and judging my what I've read on a complaint forum it's not uncommon to start having problems with this brand within about 3-5 years http://www.complaintsboard.com/compl...-tv-c4097.html

my TV is a lttle over 3 years old now, not very old for i TV i guess but i'm assuming the warranty probably only lasts a year
