Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
So are you getting some sound, just low volume, or no sound at all?
Thanks for confirming,
the issue is that the tv doesn't properly output volume levels in this situation with analog connections.
The best option here, especially since you have hdmi devices, is to keep everything digital.
Simply connect an optical (also known as toslink or fiber optic) cable from the Digital Audio Out port on back of the tv, to the optical input on the receiver, and the system should work.
You can pick up an optical cable online: http://amzn.to/2bxruXt or at any shop that sells tvs and electronics.
Do you have the AV100 or AVR100?
lets try a different approach, go into the tv settings menu, under the audio options, and look for the audio output options, for a setting to turn off the tvs internal speakers.
Under the speaker settings, the tv speakers need to be turned off (set to external),
then with those off, you need to turn the volume on the tv itself up using the samsung remote,
with the final adjustments being done on the receiver
The use of the scart converters is likely complicating this as well, these tvs aren't designed to output analog audio at all really (the case for ALL new tvs), so there are multiple things working against you here.
What are the source devices you are using? Cable/satellite box? Dvd?
Okay, each of those items should have ports on the back, so you would be better off in this case to bypass the tv for audio entirely,
and hook a set of red/white from each device to the back of the HK.
Yes, you can follow up with me later, though I'm in the US and may not be here right when you return.
They are labeled, on the back of each device you will see Audio Out, usually labeled as left and right, but they are color coded. You need a red and white from those outputs on each device to a set of available ports on back of the HK.
For example you may put satellite on the TV input mode, and dvd on the CD input mode, etc
It does not matter which you use, you just have to remember to set the corresponding input mode on the HK to pick up signal from whichever device you are listening to.
You're very welcome, Constance.
