820-2838-A overheat

Anyone think of a way the dc in board can be bad and
cause the cpu to overheat?, usually boot up one time
then freeze up and not work again till it sits and cools.
Either that or I am very unlucky with boards as I have
had 3 do the exact same thing...

This one is pulling 1 amp through the power supply and
PPVCORE_S0_CPU is down to .98v which seems would
be the result if there is a short pulling a lot of current.

It’s overheating because it’s old...but inspect for corrosion near the SMC

These are 'good tested board' from different sellers, Just wanted to make
sure it couldn't be something else other then the logic board. I guess need to
just part out all the good parts and not try to find working logic board.
