Samsung stay clear of it
I have a very expensive Samsung 46 inch 3D LCD.
About every thing that can be wrong with it IS wrong.
As I mainly use it to watch DVD via SCART (at least that quality is acceptable)
sort of learn to live with all its limitations, useless remote,
bad user interface, no settings saved... no zoom on recordings,
the list is endless.
Things change, and I decided to try the local cable company for a fast
internet connection (Vodafone does not seem to bother anything more than
GPRS 5kB /s here, deliberately throttled), and I want my servers away
from godaddy.com who are copyright violating criminals,
so that fast cable would allow me to run the servers back here again...
saves time, reduces problems, increases quality.
Now normally I watch TV via satellite, record too,
so because the cable was connected yesterday, I wanted at least to check if
teafee worked via that cable (the ethernet box comes next week).
Plugged the cable in the Samsung TV....
Indeed teafee worked.
So left the cable in.
Watched a DVD today, and all sorts of RF interference and moire on the screen.
Unplugged that cable (what else could it be..), and interference gone.
Multimeter, TV is grounded on mains, cable is grounded dunno where..
2 volts difference.
Scope, yes dirty AC volts 50 Hz with spikes.
OK, samsung saved on an insulation transformer, I thought after so many years
selling teafees they should have learned SOMETHING but no.
Made a 50 Hz isulation box:
Repeated DVD play experiment RF interference still there from cable.
Maybe I should have tried an attenuator.. but hey that gets me noise on analog channels.
So stay clear from Samsung.
I bought a HTC Android phone, it is user friendly and nicely made,
about the opposite as that S Korea shit.
Now I know why N Korea wants to nuke the south,
it is Samsung.
Does anyone know of an avalanche diode 1600V >30A which I can actually
buy a small quantity of? I need 16 of them, not 100.
