It is probably the Cold Cathode Tubes inverter that is duff.

LCDs work by having a few CCTs shining through a three layer (Red, Green and Blue) LCD screen. The CCT is like a small fluorescent lamp and it gets driven by an inverter circuit. Just like when a starter goes duff on a fluorescent lamp it will flicker badly.

They are a s*d to fix as the sets are not very user friendly and need a lot of dismantling to reach the offending parts.

@keith Bush is just one of the marketing names of Alba International and the sets are mostly Chinese made. They are usually sold through supermarkets and the like but may be badged as a variety of Brands depending on the outlet. You will probably find some Bush stuff in Tesco in the UK.
