IME, caps, drive fets and, sometimes, cold solder connections
(esp on things like transformers/coils).
Having a programmable multi-output lab supply on hand can make
it easy to decide if it's even *worth* fixing many devices
(e.g., discover the screen has been "invisibly damaged")
If you look, carefully, at the boards, you'll often see devices are
not derated adequately. I've encountered several "disposable"
devices wherein the components were actually *under* spec -- e.g.,
10V caps on 12V supplies. Works OK... for a while. A *short*
while! :-/
When recapping, always opt for 105C, ~5000hr parts (assuming you want
to keep the device and not have to repeat the exercise, again!)
Is there a 'recapping kit' for my Element?

You mentioned how youu 'listen' to a film on TV. We have two complaints
with this Element's sound:
1. Volume control is weird! adjustable from 0 through to 100. sometimes
films and shows are too loud at 1, and considering 0 is mute, not so good.
2. [may not be fault of TV, but could be the 'conversion' process] turn
volume up to 18 or 20 and it still sounds like everybody is mumbling,
barely hear the dialogue, hang on every word and THEN...music! or action
scenes erupt! and it's like that ad for audio systems where your hair is
blown straight back away from the set, big ouch! Instantly have to turn
volume down to 2 or 3, then when dialogue starts it's back up to 20 to try
and understand. Doesn't seem to be good sound balance in today's feature
films.
The reason I suggest conversion process is because after changing to the
Element TV and having become used to an old analog TV with the 'free'
converter, the volume/sound seemed to have different characteristics. this
sometimes included an 'echo' effect in those 'transition' scenes, not too
close, not too far away, just transition scenes. Distinctly hear an echo
in the sound.
Any comments about which produce better sound? Samsung, Vizio, or others?
