one did, while the "bad" monitor works fine (at least, so far). So

you say the bad mon. with the good power board i think...

I'm confident that the problem is from the power board, and given this

ok, 1-0 for me...
(ah it's a soccer score sorry..)

both power boards to examine, I also noticed that the C110 and C111
caps were replaced by Samsung when I sent the monitor in for repair

from what you noticed? The shining solderings?

earlier this year (the last month of its warranty). I'll get the
specs of all caps today, find corresponding parts on DigiKey, and post
back here for confirmation.

i think is not so vital to find the specs, only take uF and V and order a good brand of low esr type. (105c)

I will research this topic on the web, but are the Polymer caps
entirely superior to electrolyte ones? Are there drawbacks to polymer
caps?

As above i'm not an expert at all but i think.. with a good brand like Sanyo, Rubycon, Panasonic
etc, you can go quiet and live life in peace for at least 3-4 years intense-use,
it's a good idea replace all area's caps, to be sure.. like i said it's safer and instructive
to test the 5v line output for instability, or the 12v if 5v is stable.. but it is no so safe whitout
precautions so it's up to you, if the boards stays screwed on the back and face outside is more
safe.
