Electronics Repair Questions? Ask an Electronics Technician
Hello, My name is***** can help you with this. Normally this problem is one of two things. First, since you have had it repaired, the button that changes to input three may be rubbing against the plastic and you would need to make sure that it is not making it stick by wiggling it or tapping on it. The other problem I have encountered before was that something was laying on the remote control so make sure nothing is laying on the remote control. Good luck.
