Not the easiest thing to fix purely because of how fiddly it is but it is doable, you'll need to remove the button assembly and then free the PCB from the button housing, you will see 7 micro switches, these are the cause of the issue. Using a Stanley knife blade, very carefully prise off the metal retaining cover(go to the side and gently twist the tab, it will gently rise allowing for careful removal) once off be careful that you don't loose any of the components, there's the retaining clip, a plastic button and a very small metal disc pressure pad(dome up). You'll see three points of contact, two outer and one centre, around these you may see what looks like a water mark, this is probably a form of corrosion and so needs scraping away, gently scrape away and clean with Isopropyl Alcohol freshening up the contacts at the same time, do this for all the buttons and it will cure the issue. I hope this is of some help to someone, good luck and thanks, Andy.

Re: Samsung LE40B530 "FIX" for randomly changing channel, entering menu, turning off
Me neither, they feel cheap and considering the issue, are made so, why they corrode as they do I don't know but it is rectifiable, just fiddly, a pair of tweezers certainly helps.Originally posted by tom66 View PostComment
