Screen keeps shrinking

Hi Samsung Support,

Samsung LCD Model: LA40A750
OS version: 2008/11/12_001010

I've this TV for abit over 1 year now and don't have any problems with it until now. The screen shrinks after a few seconds with a dark band which is about 1/5 the size of the screen on the right. I have to change channel and return and it will be ok for a few seconds before the dark band appears again. It will be ok after I keep doing this for a number of times. I also notice that this only happen with OneHD, 7HD, 9HD channels. What could have cause this problem?

DownUnder8,

If it's only happening on specific channels, it may be either the way the specific channels are being broadcast, or an issue with the cable/sat box. In many cases, calling your cable/sat provider and having them reset, refresh or update the cable/sat box can clear up these problems.

You noted specific channels, so that may be fix the issue. Try that, and keep me posted.

Thanks for your quick reply. The only issue with your suggestion is that I don't use any set-top boxes. It is straight from the TV antennae and using the TV's own tuner. Maybe the tuner is faulty.

DownUnder8,

Ah, yes that would make a difference.

Go into your picture menu settings by pressing the TOOLS button on the remote, and check to see if your picture size is set to 16x9.

If it is, then you may be right, and your unit may require service.
