Back in the days of the Commodore 64, there was a recurring problem with the main power connection pin on the board having a hairline crack in the solder joint. All that needed to be done was reheat it. It was a simple repair that caused many techs to have some crazy moments on the repair bench.

I believe that Sarma has hit on the most probable cause.? I have had issues with the antenna pins coming loose, so the red power lead to the mainboard is a good candidate.? If you add the leakage current of the finals to the 87 ma that I measured you get the 90ma.? Could also be just a bad connection to the pin in the connector.? If you have a pin you could measure the red wire connection to see if there is 12 volts on it.
