I have a TIU rev H1 that has developed the following problem.
You press a button on the remote and the engine will respond from now to not at all.
Most of the time its between 1 to 3 second delay.
I bought a new TIU REV L and this is not happening. The engine responds promptly.
So I know its a TIU problem.
When this problem started I was running two engines, one with MTH passengers cars with light bulbs.
The problem occurred instantly. One moment the engines respond promptly. The next everything is delayed. Something happened.
I even verified on an oscilloscope that indeed there is a delay between the time you press a remote button and the time the signal gets sent to the track.
The signal level to the track is good and the signal is good, The engines always responds if a signal in sent out. It's just delayed or never happens.
I have tried all the factory resets , tethering the remote. All TIU channels have the same problem. Nothing has fixed the problem.
Does anyone have a clue as to what component in the TIU has failed to cause this and why?
