       2-8-2 Mikado Dead as door knob

       I pulled this engine:
 (HTM) http://www.lionel.com/products/chessie-system-lionchieftm-plus-2-8-2-mikado-2103-6-81299/
       out of storage and its dead as a door knob. It worked about two
       years back and then a bit of transportation happened.
       If I apply power, nothing happens. No beeps, no lights nothing.
       Changing the transformer switch does not alter behavior. The
       LionChief remote blinks fast after a few seconds when the remote
       is turned on.
       I took off the body and probed the CN1 terminals on the top PCB.
       I measure 18 volts on the CN1 terminals on the top PCB. I think
       this is the main power input to this top PCB.
       The PCB has power.  I do not know how to debug this thing any
       further though. Is there a service manual with other probe
       points?
       Also, it seems like this top PCB has a bit of white
       discoloration on the right side as shown in the picture:
       [attach=1]
       Does this look like anything diagnostic?

       I probably should not say anything but I've been having some
       problems with my O Gauge trains. I'm starting to think maybe
       it's the heat. My train layout is out in my garage and I live in
       Florida. It's really hot here. Summers the garage is like an
       oven. I just got some repairs done by MTH F3 and put in a new
       smoke unit in my Lionel Mikado.  Sense then I bring all my
       engines that have computer chips in them inside. I keep them
       inside. Take them out in the garage in the early morning for an
       hour but when done running trains the engines come back inside
       the house?
       Just food for thought. Was your Mikado stored in a area with
       high heat. I'm a retired software engineer and my passed
       computer knowledge says heat can play rough on computer chips?
