I own an Xbox 360 slim 250 GB and tried to connect it to the TV with HDMI cable. But about 5 minutes of use my TV screen start flickering and then go blank for 2 seconds. It is repeating this process every 15-30 minutes over and over. I use different HDMI cable, but it did not solve the problem. To confirm the problem I tried my Xbox on a different HD TV and it still shows the same problem. Now what to do please suggest.
