Samsung 686M 40" image shake issue at 1080p 50hz

by shadowchaz / February 8, 2009 6:47 PM PST


I have purchased a samsung 40" 686M TV, and a BD-P1500 Blu ray player.

I am having a slight issue, and that is when the blu-ray outputs a signal at 1080p (50hz) I would describe as a slight shudder and flicker. If I cycle through the source inputs it does away, likewise if I set the output signal to 1080i the shudder and flicker go away.

I've tried two different HDMI cables which has not aleviated the problem. Does anyopne have any ideas on anything I can do to get rid of the problem? Or do I need to call out an engineer?

Welcome to the forum. I'm not very familiar with the exact model you noted here (686), but do you know if it has the Auto Motion Plus feature? If it does, try toggling that to a different setting to see if the issue goes away.

Keep me posted.

LE40A686M1 and bd-p1500 dvd playback problem at 50hz (UK)

The exact model is LE40A686M1.

It has a 100hz mode, and although turning this up makes the problem worse, it doesn't go away when off, unless I scroll through all the sources, and it seems to correct the signal and display a stable image.

I spoke to the shop engineer who said it was probably the hdmi cable. I have tried three cables and I get the same effect. He then said to test the blu ray in store to see if that was the cause of the problem. On their store tv it demonstrated the same problem at 1080p when playing a dvd (50hz) so it was sent off for repair, but it has come back and they say there is nothing wrong with the player.

I'm getting quite frustrated, as i just dont know if it is a fault with the player or tv
