FT-817 almost powers up


 

I have a 817 I am working on that I picked up at a flea.
  • on battery, when POW-ON the display briefly starts (solid pattern on LCD) and shuts off (and I hear a relay click)
  • on external power, the rig does nothing (and it appears there maybe short -- supply shuts off)
Anyone seen this before??
I probed around the power connector and it seems ok
I also checked the MAIN board top and bottom and I don't see any craters.
On battery, when I power up I seem to get a good 5V at the display before it shuts off.
