HD Tuner... Tuner failed (on every hd chanel)

since a hard drive upgrade i seem to get this issue with every hd chanel sometimes it then causes me to have to reboot i.e if i go on to an HD Channel and go back to SD i get the tuner failed message again... if i stick to just SD no issues

The HD temp is 55 is this too high and is it likely to be causing the issue or would i be better looking at a new tuner?

Try a usb fan on top should cool it to around 27 degrees and should stop this happening.

sounds like HD is starting to cook things inside the case

worth taking the outer case off and see how the box responds then before looking into cooling

cheers guys will just take hard drive back out barely used it anyway
