Sorry about that I completely missed TnA last post. My best guess is it may be a small resistor on the circuit board that has gone bad. I had similar issues with two TnA engines and once I replaced the component on the circuit board it started working fine. These can sort of be a pain to replace if you do not have a good soldering iron and a solder extractor.
Here is the component that was bad on the TnA engines I mentioned. You may be able as a test to put a small piece of wire or a screwdriver across the two ends to short it to test if it is bad:
