Many makes and models connecting with HDMI I can't agree it's just Samsung.
TRY THIS TEST. Connect with Component cable.
I am trying to get the number of people affected by this nagging blinking issue with the latest Samsung led tv's. If possible it would be useful to include as much details about the tv including the model number, firmware version, the input source which is causing the problem, frequency of the blinks etc.
My aim is to get the numbers together so that Samsung will take note, so far it doesn't look like they are treating this as a major issue, but we all know it is.
My TV: Samsung UE46C8000 ( 3d led )
Firmware version: T-VALDEUC-3005.1
Problems with: Sky hd box ( Thomson ) which has been reset by sky and has had a software update. Also had hdmi cable change.
Sony bdp s-370 bluray player again had a software update and has changed several hdmi cables to make sure it is not a connectivity issue.
WD passport 500gb external hard drive connected to usb port on the tv.
Frequency of blinks: Variable and random, sometimes the tv works just fine, but once it starts blinking which is just after putting it on, the blinks might happen anyway around 2 seconds to 20 seconds.
What i have tried so far:
Changing hdmi cables, disconnecting all equipment completely from the tv and trying one input at time, to rule out individual input as an issue.
Setting all auto settings to off, like auto protection, mpeg noise filter, digital noise filter, led motion plus, smart led, auto 3d.
Resetting the entire system to default settings.
Software update which gave the above version, previously it had 3003 in the end instead of 3005.
None of these actions seem to have had any benefit and the blink still remains.
