Any Samsung tv engineers read this NG?

I have a Samsung LE40M87BDX LCD. It suffers from the known and common scart
interference issue on EXT2 and slightly on EXT1.
Is there a fix for this yet?

I connect my Sky+ box through EXT1 (RGB) and in dark solid scenes you can
see very faint scrolling horizontal lines. EXT2 is un-watchable.

TIA

I'm not a samsung engineer, but we have a similar problem on a cheap TV in
the kid's room.
If you look closely, are you seeing the ghost of another channel?

It seems to be punch-through on the video mux, where a small amount video
from the internal tuner leaks through the mux ( electronic switch ) which
selects the SCART input. Or it may be cross-talking on the scart cable (
the TV tuner O/P feeding onto the scart crosstalking onto the incoming AV. )
The only fix for us is to leave the TV internal tuner tuned off-station, or
pull the RF ( aerial ) input to the TV.

I could isolate it to one or the other by un-wiring the scart O/P from the
TV, to eliminate x-talk in the cable. The cable is fully screened anyway,
and the crosstalk is present when AV is selected even with no cable
connected. So I suspect the mux rather than the cable.

Try the workarounds I mentioned.

It's a common and known problem on some Samsung LCD. Apparently, the
internal PSU is too close to the scart socks causing scart interference.
Strangely it does not effect all tv's though.

That's no good because the noise shows up on the picture as snow. A better
idea is to fit a cheap inline modulator in the aerial lead set to output on
an unused channel and tune the TV to that channel before switching to AV.

A method that is good to stop xtalk is to use a one way scart lead.

Are you serious ? that's like saying Comet really do have engineers!
