Anyone have any info on this board that is inside the 50-1013 IR remote lock-on?
My 4 year old son loves the IR remote because it is so simple. We had a derailment the other day including a brief short which popped the circuit breaker on the Z750 brick we use to power it. I reset everything and now the voltage from the brick seems to be passing right through the lock-on and the train runs at max speed. There is no response to button presses on the remote and the little green light on the lock-on remains off. There is no visible evidence on the board of a specific component failure. I was considering replacing the MOSFETs since the brick voltage seems to be passing right through them. With power off, they do not measure shorted. I hope the little microcontroller did not take a hit. The AC seems to be isolated from the DC to protect the little brain box but the fact that the light does not come on scares me a bit.
I want to like MTH products because they are nice when they are working, but it seems every MTH product I own has trouble trouble with electronics at some point. I have had TIU issues, an HO PS3 diesel board that overheats, and now this. All in the past few months. Are MTH electronics just designed particularly weak?
