Help Issue with S2 + HDMI/MHL cable

[psydex]

Just recieved the MHL Cable i ordered from ebay. Everything works well except the fact that if i leave the phone without touching it for about 5 sec. - on tv pops up message Hdmi not available while application is running. Application will dislay on phone only. Again, this is only if i don't touch the screen for short period (also when attempting to play video or run camera app), thought when i'm browsing or playing games - it's ok.

Any ideas how to fix this?
