PC to TV HDMI problems

[karochejasna]

Hello. Today when I turned on my computer it had no signal from HDMI cable to my TV. I thought it may be damaged and broken and bought a new cable but new cable is not working also?? I am browsing internet, searching for solutions but I just cant find any that would fix my issue. My TV[http://www.p4c.philips.com/cgi-bin/cpindex.pl?ctn=22PFL3405H/12&hlt=Link_ProductInformation&mid=Link_ProductInformation&scy=DK&slg=AEN] and my graphic card is AMD Radeon HD 7700 Series

Did you change input on your tv to where the hdmi cable is connected to?

Yes. It all worked before.. I just woke up next day, turned on computer, tv and all I see is "No signal''

So try a different device in the TVs HDMI port, make sure a PS3 or PS4 or something works in the same HDMI input. If it does its going to be an issue with the graphics card. obviously try the computer with a regular monitor if you have one you can hook it up too.

Well now I am connected through VGA to the same TV. It was happening to me before too but somehow it got fixed by itself

Some weird thing I just realised. Downloaded the Custom Resolution utility and it detects my HDMI cable? Then why does my CCC is not detecting it? http://imgur.com/YPXGhHm Or its not what I think it is?

I had this issue like few times like I said before, but somehow it just went through and worked again. What can be the cause of this? And I think I got onboard graphics too but in bios its set to PCI. I even did clean reinstall cause it worked for me once too year ago - started to install when was connected to VGA cable but when setup does its all monitor adjusting etc. I switched to HDMI cable and it got working again.
