I have a Samsung tv. When you are watching the tv changes its source ie HDMi to tv to Pc etc without you asking. You change the source back to the one you want and this works for a short while and then wanders as described above.

That's not an answer I gave its just to know if ytheirs an input source button on the set and if its ok, ok one last check and I stress a check and not an answer is the remote itself TAKE BATTERIES out of remote so its dead then try set again is it still the same let me know please

Customer: replied 4 years ago.

Source/input button seems to be working ok

Hi Dave

No what I mean is if you take the batteries out of the remote so the remote is dead is it still switching inputs?

Dave I do know the problem its just that I have to eliminate the 10% of other things that can be causing this so one is the source button being stuck which you have cleared and now the remote itself

Hi Anthony

took batteries out of remote adjusted manually but problem persists

Hi Dave

OK thanks for covering all that
The problem you have is with the tact switch on the set itself that is a switch that lives just below the source button on the set itself its gone bad, now you can disconnect the function board that the switch is on (volume\channel change\source)by pulling out the lead that feeds it, the function buttons then wont work however problem will be resolved, while your in there you could get the partnumber from the function board and order at a later date

Let me know if you dont understand anything here or if you feel this is out of your scope
