I have removed the console, checked all the connectors. Here is what I find. There is power to the circuit board. All of the functions of the board work except the display. The fan works, the resistance level changes, the keypad works. All these go through the main board. On the board there are several marked test points. I can see several ground points and some marked with voltages. I have tested several points such as one marked 6V and it measures correctly. There is a 3.3 test point. It measures correctly. As far as the display is concerned, it has red and black wires soldered directly to the board. That connection looks sound and I don't see any solder bridges or anything like that. If I measure between the red and black I get 0.0 V. If I measure from either of the red or black to a ground test point I get 1.8 V. Is is possible to determine if the display is bad or it the main board is just not sending a signal? Or for that matter, am I just out of luck.
I think we have done all we can. I noted that when I pressed the display button on the key pad, I would get 0.38 volts between the two terminals on the display. I am fairly well convinced that the problem is the display. I removed it and thought perhaps I could get a number or something from it, but it has nothing on it. I also thought I might buy one from the internet, but I have no way of telling its specifications. I think I will just have to make a decision on whether to spend the $300 for a new console or not. I appreciate your help. Respond and I will accept your answer.
