Samsung LCD TV "Not supported mode" problem

by iamsagevsal / February 15, 2009 5:07 AM PST

Recently my samsung LN-S4092D LCD TV turned on into a never seen before white configuration screen with what appeared to be sort of a bios setup. It was not possible to leave that screen without attempting to change one or more settings. I set the resolution setting to 1080i and now I cannot view anything and get the famous "not supported mode" message on the blue screen. My question is does anyone know how to get back to that bios like setup screen so I can change the resolution back to 720? That setting is not in any of the normal setup screens of the television set.

Were you attempting to access the service menu?

Service Menu

In reply to: BIOS screen...

I am not sure what the service menu is. The TV just booted into the white screen configuration with a couple of settings which included one for resolution with three selections, 480, 720 and 1080. Obviously it normally boots into the blue screen. It was set at 720. Could not exit the screen in any way until a selected a new resolution. Now I cannot get any input through the HDMI ports. I get the Not Supported Mode message. I want to try to get back to the white screen menu to change it back but don't know how to do that.

I'm not sure I've seen that screen before.

Forum members - any ideas here?

We'll see if some of the guys here can just in and offer any input. If not, I'd suggest getting the unit serviced.

Cable box?

Are you sure it's a menu generated by the TV and not whatever device you have attached (cable box, dvd player, etc?).

When you say you can't get any input through the HDMI ports, what devices are you trying out? Hopefully you have more than one HDMI device :).

To access settings on a motorola box
by clicq / February 17, 2009 12:52 PM PST

If you have a motorola HD box, turn it off, then hit the menu button on the box. It should turn on and give you a menu, I think... haven't had a box for awhile now.

If that doesn't work, maybe somebody else can chime in, or you could try calling customer service for comcast.
