When autotuning the set goes throughs all transmitting channels, shows to be receiveing all channles, but seems to be tunes indefinitely, and no channels are locked, the memory IC inside the set has got damaged. In normal case, the TV will tune to all available channels at that tiime, in air or through the cable, whatever the case may be, tune up to last channel, and will stop, and will display the first channel it has got. Then we have to make adjustments on channels.
The memory IC i stated above is a small IC with 8 terminals, and can be located very near to system control Ic, at system control section. In some sets, it will be SMD type [Surface Mount Device], and in otheres will be of DIL type [Dual In Line]. If it is a DIL type, it is very easy to replace. If it is SMD type, proper care should be taken when replacing it, not to damage any track on circutit board and nearby components.
Open your TV, locate the IC and desolder it out of the printed circuit board, go for a same type and number, replace it. This will solve your problem.
