First check the picture and effects settings in the onscreen menu in case something has been altered.No model no.given but as a general rule any Top of The Pops special effects type symptoms (picture faults) in LCD TV's usually means replacing the main pcb board as component level repairs of the video processing section is unviable.Sometimes with these you will find a seperate signal input board with all the scart and hdmi sockets on,this to could be at fault and require replacement.As with many items these days parts may no longer be available.
