Windows 7 PC to LCD TV "No Signal"

[slayman]

My laptop PC is connected to a Samsun 32" LCD tv through hdmi-hdmi with a DVI->hdmi adapter on the PC end.
I've been using this for 4-5 months with no problems.
But suddenly I get a "No Signal" message on my TV, One second it was hooked up and then it just turned black and I keep getting the "No signal" message.

I've tried re plugging, rebooting PC and TV, changed resolution and refresh rate to the native settings.

If I check the nividia control panel, it detects the Samsung TV, when I re plug it, I get the normal flickering on the PC screen, but it's the same on the TV; "No signal"

I've tried changing the HDMI cabel, no success, changed ports, no success.
The only thing left is the adapter, it may have been burned or something, but it seems to be working since my PC can detect the TV.
And I don't really waste money on a new one to only find out that it did not work.

My graphics card is a GeForce 8600M GS.

This is the first time I've had any problem with this connection.

It sounds like you've already done quite a bit of troubleshooting to address the "No Signal" issue between your laptop PC and the Samsung TV connected via HDMI using a DVI to HDMI adapter. Since you've tried different cables, ports, and resolutions with no success, let's explore a few more steps to help resolve this issue: 1. Update Graphics Drivers: - Make sure that your Nvidia GeForce 8600M GS graphics card drivers are up to date. Sometimes, outdated drivers can cause display issues. You can download the latest drivers from the Nvidia website. 2. Check HDMI Port and Adapter: - Test your laptop's HDMI port with another HDMI device to ensure that the port is functioning correctly. - If possible, try using the DVI to HDMI adapter with another device to see if the adapter is the source of the problem. 3. Power Cycling: - Try power cycling both your laptop and the TV. Turn off both devices, unplug them from power, wait for a few minutes, then plug them back in and turn them on. 4. Reset TV Settings: - Check if there is a factory reset option in the TV's settings. Performing a factory reset can sometimes resolve connectivity issues. 5. Check TV Input Source: - Ensure that the TV is set to the correct input source for the HDMI connection. Use the TV remote to cycle through the available input sources to find the one connected to your laptop. 6. Inspect HDMI and DVI Ports: - Examine both the HDMI and DVI ports for any physical damage or debris that may be obstructing the connection. 7. Test with Different Device: - If possible, try connecting a different device to the TV using the same HDMI cable and adapter to determine if the issue is specific to your laptop. If after trying these steps you still encounter the "No Signal" issue, it might be worth considering replacing the DVI to HDMI adapter as it could be the culprit despite it being recognized by your PC. Sometimes, adapters can have internal issues that prevent proper signal transmission. Let me know if you need further assistance or if you have any other questions!
