I have built a Media PC using an Intel i3-540 Core i3 Dual-Core Processor with on-board HDMI output. This connects to a Samsung PS42E7HX/XEC TV. I have tested this several times and it was working fine, but now I just get 'No Signal'. I have tried all combination of power up sequence.

I have plugged my laptop into the HDMI cable to the TV and that works fine, suggesting that the TV and cable are OK. I have used another HDMI cable to plug a different TV into the media PC and that works fine, suggesting that the PC is OK.

Any ideas what can be wrong here? It has me baffled.

The only possibilities I can think of:

Is either of your connections loose? HDMI is an all or nothing thing, if it slides out just a little of one connector it will kill all signal.

Did you connect to a computer monitor when not connected to the tv? If so, did you change your resolution? If you did, it is possible that you chose a resolution that is outside of the tv's range. I know my tv's limit is 1920x1080 (pretty sure). If I go above that setting, then I get the 'No Signal'

If this is not the case, then good luck because I have no clue.

Hope this may help.
