Jeff,
I have had a couple of these with shorted smd caps, specifically C18172 next
to the 3.3V regulator.

Make : RCA
Model : F32665
Chassis : CTC203CH3
Problem : Shuts down on power up.
Traced problem to the F2PIP module.
IC U18101 ( LM317T) in the 3.3V regulator circuit is only putting out 1.2V
on pin 2
Tried a new IC , no change. Something seems to be loading down the 3.3V
line..........although resistance reading to ground is not low at all ,
almost 1 meg.
By cutting a few supply feed traces I can get the 3.3V line to come up.
I did pull the main PIP processor IC and still have the low voltage.
Has anyone seen a common fault on these F2PIP board?
These boards appear to be on back order for the time being
