I have a hisnese 20-ish inch tv that is about 6 years old. It started having a problem about a year and a half ago where it randomly turned itself on and changed channels on its own. I opened it up and dusted it out (not much dust) and messed with the settings a bit and vola it worked. Well, then a few months ago it started up again. I dusted it out (not really anything) and it still had the problems. Then I just unplugged it and let it sit for a month. I tried it out and it worked fine for the past two months or so. Well, it started having the problems again and I dusted it out (really nothing) and it had no effect. Anyone know what I should do other than pay someone to fix it?
