So if one is getting the "not supported mode" on a Samsung TV with it connected to a HD receiver using a HDMI cable but the receiver does not have any component outputs do I have any options other than buying a new TV?

I have a Samsung HLS6188WX/XAA DLP TV that will not work with a SkyHD receiver (Amstrad DRX890-C) when connected using a HDMI cable. The TV worked fine using a different cable providers HD box and with my DVD player (using HDMI).

Time Warner support pointed me to this thread after I called them. I have a Samsung FP-T5084 and couldn't get non high def channels to work over HDMI. The tech gave me totally wrong advice. What I figured out is very simple: my TV doesn't support 480i over hdmi. All I had to do was disable 480i output in the cable box setup. Might help someone else.

I have a HDTV that doesn't except 480i over HDMI either. Thanks for posting this so others know to look for this in the manual of the TV if they are having this problem like you.

Smile Not Supported Mode Resolution

I called Samsung, because I came across that same error while trying to install my ps3 to my 42 " plasma. The representative asked me if I had checked my resolution settings for my ps3. My ps3 was outputing 1080p and my tv is set to receive 1080i.
So if you go to your display settings on your device and customize the settings to only receive 1080i vs allow it to autoconfigure this should resolve your issue (480p & 720p can be enabled as well).
Kudos to Samsung.

Default similar situation with TWC cable box and Samsung TV - problem solved

I know this is an old thread but I figured I should post this just in case it can help someone. My situation is similar to the original poster's scenario.

Starting a couple days ago my cable started wigging out... pixalating, freezing, etc., so that meant it was time to restart my Time Warner Cable box. When I did that, it got stuck in the boot sequence at L-13 (I think), so I called TWC and they suggested I replace the box. So I took it in and swapped it out for an older crappier model. Brought it home, hooked it up with HDMI, and splat "NOT SUPPORTED MODE" from the tv. I swapped that box with TWC again the next day. Brought it home, hooked it up with HDMI, and again, "NOT SUPPORTED MODE". At this point I knew the problem was either the TV or the hdmi cable. So I hooked up my laptop via it's hdmi out to the tv as I often do, and it worked, so that meant the tv was working fine. I pulled the hdmi cable from the laptop, plugged it into the cable box, "NOT SUPPORTED MODE". So, after I read this thread, I hooked up the cable box and tv using, not component, but regular old avi cables (red and white for audio, yellow for video). Using that I could see everything, HD channels included. I went into the settings menu on the cable box > went to display settings > went to output resolution, and sure enough 4 different outputs were selected. 480i, 480p, 720p, 1080i. I selected the "auto select" option, and the box automatically unchecked 480i. I switched the source on the TV back to the cable box's hdmi port, and TADA! Everything works now.

I'm not sure what caused 3 different cable boxes to suddenly start defaulting to 480i, (firmware update?), but that's what was causing the problem. When this first occurred and I called TWC, they said tons of boxes were locking up during the boot sequence, so I'm assuming they might have distributed a jacked up image or something. Either way, bottom line is, use something other than hdmi to get access to your cable box's display settings. Uncheck 480i, and that might solve an issue between a samsung hdtv and a TWC cable box.

I had a similar problem where my Samsung TV gave "Not Supported Mode" with my Time Warner cable box. What I did was
1. connect the cable box using video cables (red,white and yellow) and the HDMI
2. Switch TV source to Video mode to get the initial picture from the cable box
3. use the Cable remote go to Settings, select 'High Definition' and then 'Output resolution'
4. Disable all allowed settings other than 1080i
5. Switch TV source to HDMI

This worked for me, the cable box only outputs in 1080i which the TV supports

Unhappy HELP!!! Not support mode for samsung plasma tv

My son hit the source button on the TV to get out of the AV mode, when he did that he got a menu screen that appeared on the TV, which the last time I saw was when comcast came to set up the HD cable box, then the cable box went crazy displaying 43P, then we got the "not support mode" flashing on the screen. From reading this thread I have a feeling it might be the cable box needs to be reset to 1080i or the TV. Can any help out? When we go to settings Channel is greyed out and we are unable to edit it. Don't know what else to do

Default Solution Following Visit from Time Warner

Maybe I missed this in the thread (as I tried a few of the suggestions I could understand) but what the TW technician did was very easy. Samsungs don't typically support the necessary code (which was stated earlier) and the boxes typically start off at 480. When the Mode not supported message appears, change your channel to a High Def channel right away. The channel should work and then you can go into the settings and make sure it's set at the correct input (1080 or whatever you need). Can't believe I could of very easily fixed this myself--2 day wait. Good luck

Thumbs up samsung tv not supported mode

Today I had the same problem. I have a Samsung LNT2642 and just exchanged my Time Warner Scientific Atlanta Set Top Box (STB). The box booted ok, but then I got the "Mode Not Supported" message. Here's what worked for me:

1- Remove the HDMI cable from the STB.
2- Connect the STB to the TV via Component Audio Video Cables.
3- Change the TV input to Component. (You should now have picture and sound.)
4- On the STB go to Settings and select "Devices"
5-Scroll to Audio: Digital Output and select HDMI.
6- Exit "Devices", find the "High Definition" submenu (left/right keys) and select "Output Resolution".
7 Remove "480i", add "480p", "720p", "1080i" and "Auto-Select", then exit the menu.
8- Remove the component cables and reconnect the HDMI cable. You should be good to go.

I hope this helps.

ED: After posting, I saw how many others had the same solution... I guess I should have read the entire thread before posting. Sorry!

This is in spite of the fact that the cable box supports HDMI and has an output jack and the TV has two HDMI input jacks and is supposed to receive HD signals via the HDMI cable.

I should also explain that this particular HD cable box was working fine with a previous Polaroid HD television (I bought two weeks ago, but returned on Tuesday) and the HDMI cable linked up to the previous set. Because of other problems with the Polaroid TV (all of a sudden, a green blurry snowy picture and audio noise, then no picture or audio at all), I had to return it and decided to get the Samsung instead. Therefore, unless the former tv when it went "on the fritz" somehow damaged the cable box (or the Polaroid's problem was caused by a failure of the cable box), I would conclude that the cable box is certainly capable of and should be delivering a signal via the HDMI cable.

When I hook up the cable box and Samsung TV with component video-audio cable, I do get picture and audio and HD on the HD channels. It's just that I'm supposed to be able to use HDMI with this cable box and TV and would prefer that because of the superiority of HDMI cable to component video-audio cables.

I've been on the phone over the past two days four different times with the Samsung folks (who are claiming that the fault is with the cable box) and four times with the Time Warner folks (who claim that the fault is with the TV). To be fair, I should add that the customer service folks from both Samsung and Time Warner have been very good, helpful, and patient; it's just that neither can solve the problem.

Here are some things I have done: 1. Early on I was able to program the cable remote with the TV's code in order to use my cable remote with the set. 2. Because I was advised by Samsung that the TV does not support 480i, at Samsung's and TW's suggestion, when I went through the cable box's picture format "wizard," (simultaneously engaging the "guide" and "info" buttons on the cable box) I disabled both 480i widescreen and 480i standard format and enabled 1080i, 720p, and 480p widescreen and 480p standard. No luck there -- still the same "Not Supported Mode" when the box and TV are linked with the HDMI cable and my source is set to HDMI. Actually, I tried to enable the 480i also just to see if that would work, but it didn't. 3. I've tried "pass through, fixed, upconvert 1, and upconvert 2" on the cable box -- still, no luck, still get the "Not Supported Mode" message.

I've tried every setting I can think of with both the cable box and the TV, to no avail. As I say, my component video-audio cables do provide me even with HD on the HD channels, but I can't help but believing that I should be able to use the HDMI cable instead and not be having this problem. The customer service technicians at TW and Samsung, although very helpful and patient, are stumped.

Any ideas for a solution? Or is it just possible either that: a. the cable box was damaged by the previous TV when it suddenly got a green, snowfilled screen and then no picture nor sound at all and therefore the box should be swapped out; or b. the Samsung TV has a "quirk" and should be exchanged????

Thanks in advance for your ideas.

Default This might help

Unplug actual incoming cable line from cable box. Unplug cable box from outlet. Wait one minute. Plug cable box back into outlet. Once all lights on cable box are out (its rebooting) plug incoming cable line back into cable box. Using Comcast remote eventually power off cable Box then press cable and guide together. A menu comes up. You need to scroll down an change PASS THRU mode....to 16:9. If you have both hd channels and regular (4:3) then go to 4:3 and change that to STRETCH.

Found this forum via google search - same "Not supported mode".

Older Samsung TV with Motorola HD DVR box (comcast/xfinity) started giving me this error out of the blue. Swapped cables & inputs to determine the only issue was via the cable box.

This box has controls on the front of it for setting things like format, etc. I noticed that the box was showing 480i format. I tried pressing the format button to change it (have had to do this before when it had been changed inadvertently). For some reason though, I was locked out.

Held down select button for 20 seconds and then was able to adjust the format (seemed to unlock it)

Default A solution to Mode Not Supported for indoor antenna users - no cable or STB users

I am using an amplified HD Wineguard indoor antenna with a 60" Samsung HD. (Antenna cable running directly into the TV - no boxes between antenna or TV.) I kept getting the Mode Not Supported message on this one local station that I KNEW I should be getting. So... here is what I did and it worked perfectly. I turned the TV off. I removed the antenna from the TV and powered the antenna off. I moved the antenna 90 degrees to an adjoining wall. I turned the TV back on first. I plugged in the antenna into the TV and powered up the antenna. Voila! I am getting 35 local Kansas City channels - all of them perfectly - for now anyway.
