Hello my name is Anthony
Thanks for the Question
The problem is bad tact switches on the set itself that is the volume control ON THE SET, the contacts of the switches for volume up and down can oxidise and behave like they are being pressed, it can happen more often to sets that are in a warm humid climate, the solution is
1 Replace the switches (tedious)
2 Replace the sets keyboard (volume-channel change etc on set)
3 Disconnect the keyboard by pulling the lead that feeds it, this will clear the fault and you can use the remote control
as normal (keyboard is seldom used)until you decide if you want to replace the keyboard or the tact switches.
Option 3 will get the set running again do you think you can do that yourself?its a matter of getting the back of the set off and finding the circuit board behind those switches on the set (volume-channel change)then pulling out the ribbon lead that feeds.
Please let me know if you need more help with this.
