HDMI output

Hello,Got a problem here with my Acer Aspire 5741g,(ATI Radeon HD 5470)which I have connected to my TV via Hdmi-cable.This have worked fine since I bought
this laptop.Now sadly this is not working, the screen on the TV is black and no sound either through the Hdmicable.
Realtek hdmi output not pludgged in it says...My question is how do I get this to work again.

Somehow it seems that the output is not activated....how to activate it?
Appreciate if you could help me.

Thanks Anders (in Sweden)

  1. Only thing I can think of is to try pressing the Function (Fn) key plus the F-key with the picture of the monitor on it. May have to wait up to 10 seconds to see if there was any effect. This controls the mirror, laptop only, external only, etc display options.
  2. Thanks for your reply,but I've tried that to no effect...
  3. Tried uninstalling and reinstalling the latest realtek and graphics drivers? Sorry if this is basic but hard to help since I can't actually see it :)
  4. yeah,tried to uninstall and install,with no success.
    It seems that the hdmi-output is turned off.I don't get it.
