Getting "No Signal" on TV after connecting Xbox to monitor via DVI and reconnecting ...

OK so, I connected my Xbox 360 to my computer monitor via a HDMI to DVI connector because my brother was using the TV to play his PS3. Now today, I set my Xbox back up to the TV on the HDMI 2 port on my TV (I only have 2 HDMI ports on this TV) It is a Sanyo.
I then started my console like normal and it wouldn't display on my TV. I have tried resetting the settings by holding "Y+RT" on the controller when the system boots, nothing. I have also tried holding the power button for 10 seconds when I boot the console,
nothing again. I tried hooking my console up via component cables and changing the input to "video 1" where the component cables where plugged in, those do work. I also tried blindly navigating the dashboard and changing the resolution settings, nothing again.
I have also tried swapping out HDMI cables, nothing yet again. I also have tried setting my Xbox up on another TV, it worked with the HDMI cable I was originally using that would not work on MY TV. I also decided to leave the HDMI cable in HDMI 2 and plug
it up to my brothers PS3 (he was using his component cables to play) and it booted up just fine and asked if I wanted to use HDMI display and sound with this console. So, the problem is NOT the cable, it is NOT the TV port, and it is NOT the Xbox port. I believe
that there is a "handshake" problem between the Xbox and TV and I do not know how to fix it. PLEASE help me out here, I want to get my Xbox back working again ASAP.

Thanks,



:)

 

Подключение к монитору [Translation - Connect to a Monitor]

Доброе утро! Снова все сделал как описано в рекомендациях по монитор сначала думает, а потом пишет что нет сигнала HDMI. В настройках консоли выбирал подключение и через HDMI и автоматически, результат тот же. Подключал через переходник HDMI to DVI тоже
самое происходит.Подключаю android PC -монитор изображени показывает.

-[Translation - Good morning! Again everything is done as described in the recommendations on the monitor first thinks, and then writes that there is no HDMI signal. In the console settings chose the connection and via HDMI and automatically, the
result is the same. Connected via the HDMI to DVI adapter, the current is connected to the Android PC-monitor image shows.]

 

No More Video Output to Monitor

Hi.

I'm going to try and be as detailed as possible with this one. About to pull hair out.

----------------------------------------------------

Materials On-Hand:

Xbox 360 Slim (The Culprit)

Xbox 360 Pro with HDMI Output (Alternate Test Subject)

Laptop Computer with HDMI Output (Alternate Test Subject)

HDMI-HDMI Cable (Works Fine)

HDMI-DVI Cable (Works Fine)

Dell 2408WFP Monitor (Has DVI Port, HDMI Port, Composite Video Port)

Dell 2208WFPt Monitor (Has DVI Port)

40" Sony LCD TV (1080P Capable)

60" Sony LCD TV (1080P Capable)

----------------------------------------------------

History:

- For the past 7 months, I've had my Xbox 360 Slim connected to my Dell 2408WFP Monitor with an HDMI-HDMI Cable. No issues.

- A couple of weeks ago, I lent my xbox to a friend a couple doors away. He has a Dell 2208WFPt monitor, which does not have an HDMI Input. I gave him an HDMI-DVI cable to use, and it worked on the monitor with no issues.

- When I got my xbox back, it refuses to output a video signal to my Dell 2408WFP Monitor via HDMI-HDMI or HDMI-DVI. Nothing I do can get it to output to my monitor (which it was working fine with for the 7 months prior to me hooking it up via HDMI-DVI to
the Dell 2208WFPt).

----------------------------------------------------

Configurations Tested:

Xbox 360 Slim + HDMI-HDMI Cable + Dell 2408WFP Monitor = NO Video/Audio

Xbox 360 Slim + HDMI-DVI Cable + Dell 2408WFP Monitor =
NO Video/Audio

Laptop Computer + HDMI-HDMI Cable + Dell 2408WFP Monitor = Video GOOD (Proves that 2408WFP HDMI Port and HDMI-HDMI cable both work)

Laptop Computer + HDMI-DVI Cable + Dell 2408WFP Monitor =
Video GOOD (Proves that 2408WFP DVI Port and HDMI-DVI Cable both work)

Xbox 360 Pro (Borrowed from Friend) + HDMI-HDMI Cable + Dell 2408WFP Monitor =
Video/Audio GOOD

Xbox 360 Pro (Borrowed from Friend) + HDMI-DVI Cable + Dell 2408WFP Monitor =
Video/Audio GOOD

Xbox 360 Slim + HDMI-DVI Cable + Dell 2208WFPt Monitor =
Video GOOD (Proves that Xbox 360 Slim still outputs DVI Signal OK)

Xbox 360 Slim + HDMI-HDMI Cable + 40" Sony LCD TV =
Video/Audio GOOD (Proves that Xbox 360 Slim still outputs HDMI Signal OK)

Xbox 360 Slim + HDMI-HDMI Cable + 60" Sony LCD TV = Video/Audio GOOD

----------------------------------------------------

Troubleshooting Options Attempted:

Factory-Reset Dell 2408WFP Monitor

Turning Display Discovery Off

Turning Display Discovery On

Attempting to Reset Display Settings with Right-Trigger + "Y" Button upon Boot

Hooking Xbox 360 Slim up to Dell 2208WFPt monitor, setting a lower resolution, and hot-swapping to Dell 2408WFP monitor (Both HDMI-HDMI and HDMI-DVI Cables)

"Blindly" Navigating Menus while hooked up to Dell 2408 WFP monitor (HDMI-HDMI and HDMI-DVI) to modify Display Discovery settings and selected resolutions

Hot-Swapping between Xbox 360 Pro (Borrowed from Friend) and
Xbox 360 Slim

Hot-Swapping between Laptop Computer and
Xbox 360 Slim (HDMI-HDMI and HDMI-DVI cables)

----------------------------------------------------

With all of the above, my Dell 2408WFP Monitor immediately goes into Power-Save Mode when the
Xbox 360 Slim is hooked up to it. The monitor works with another xbox, a laptop, and via multiple cables. Therefore I know that the ports are good, the cables are good, and the monitor is good.... but it refuses
to display anything from my particular Xbox 360 Slim. Ever since being hooked up to the Dell 2208WFPt monitor via HDMI-DVI, it simply will not work with the Dell 2408WFP Monitor. I cannot think of any other options.
The Xbox 360 Slim works fine on any other display I try it on. Another Xbox works fine on the Dell 2408WFP Monitor with both the HDMI-HDMI and HDMI-DVI cables. As a reminder, the
Xbox 360 Slim worked just fine with the Dell 2408WFP monitor for 7 months via the HDMI-HDMI cable.

I appreciate any assistance that can be provided. I don't know what else to do. It's very mysterious. Thanks.

 

Have you tried asking an ambassador?

 

Yes, I have asked ambassadors and called Xbox Support like 4 times and no one has given me any way that has even gotten close to fixing this issue.
