My Laptop HP G62-340US connected to TV via HDMI and used to work perfectly on Windows 7 . There was power failure and since then it stopped working.
So I uninstalled everything and installed original Catalyst control center that came with HP. Now in the CCC it shows built in display and the LG TV on HDMI. But when I switch the input on TV it says no Signal. I tried everything I could but it doesnt seems to fix the problem.
My Laptop was dual boot so I tried in Windows 8 and still a blank screen.
Yesterday finally fed up with the isue and I restored the laptop to factory setting and its still not working.
I tried another TV and it doesnt work there as well.
I tried 3 different HDMI cables and problem still exists. These cables works fine with another laptop.
in the device manager when I click on properties windows says this device is working properly.
So now what? Has the GPU card failed? IS there any solution?
