John- I don't have the ability to inject 3mV @ 1.5KHz into the microphone connector. Therefore I get zero output unless I speak or whistle into the microphone. Just rotating the main dial makes no difference. I don't see a number, just the output scale that reads up to 100. I see that for "TX Total Gain(430M)", the correct output setting is 17.5 Watts. It isn't until a later step that you set (Po Max(430M) for 35 Watts. If you can't get the power up to either value, the UHF amplifier module may have a problem. Since it isn't completely dead, you may decide to keep it that way rather than pay the price for a replacement. I wouldn't be surprised if you can buy a used IC-7000 for little more than the price of the module! I'm sure I pressed the "F-4 (SET)" button. I suppose there could be a firmware upgrade needed.
