I had an intermetent issue with my tv i tried allsort's but then found the AV board inside the tv had some componant's that  had corrosion / corroded.  After cleaning with isopropyl alcohol and a toothbrush I then resoldered the culprits with new solder. It has now been running for ages without an issue. You could also google the tv's model number , ie Phillips 32---------led tv dvd combo channel randomly changing issues or channel switches over by its self. If you do not find anything in relation to your problem try  writing it another way but keeping the make and model number.
