I have a tiu (rev. 13B) with no signal on fixed 1. It worked when I first bought it used a few months ago then suddenly stop while using it. It started with having difficulty controlling certain features.
I have it powered through fixed 1 but have tried with AUX power input and results are the same. Variable 1 and 2 work in both fixed and variable and fixed 2 also works. Just no signal on fixed 1.
With a loco on fixed 1 I can start it up, shut it down, make it move forward, blow horn and bell but can not slow it down, shut off bell, or use any softkeys. I just get a CHECK TRACK on the screen. I can stop it with direction button. I assume I'm getting some sort of signal because of the things that do work but not enough to get everything to work. Also I get nothing when checking for track signal. Is this a common type failure and if so is it something easily fixed? Hope I have given enough info. The other channels work so I'm fine now but would like to fix it if possible. Thanks for any help.
