I have been having the same old problems of it hanging up when I change channels or go to the guide. I restart it and it sometimes hangs at the welcome screen. All I found on it says replace the HDD. So I went and bought a refurbished WD 320 gig hdd. I used winmfs to backup the old drive and restore to the new drive. All seemed to go OK. Put the new drive in the box and plugged it in and get nothing. Tried putting the old hdd back in and still get nothing. The fan is spinning and the power light on front panel is green, but no signal to TV. Tried it on a different TV and same result. How long does it take to power up before I should get to the welcome screen. Can it take more than 2 mins or so? Any other ideas?
