so before i have had no problems i could connect my laptop to my tv via hdmi with no problem until now. i plug the cord in and the tv shows up and it acts like it is in extended display mode but the tv is blank. i know it is not the cord or hdmi port because it works fine on different tv. i have tried uninstalling and reinstalling the video drivers but no luck.. please help im about to rip my brains out. laptop is a hp dv5 2135dx

Did you try switching to projector mode with Windows-Key + P ? What happens if you go to system settings and select the TV as main monitor?
