Source/input button seems to be working ok

Expert:  info tech replied 3 years ago.
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

Expert:  info tech replied 3 years ago.
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
