I've just got my raspberry pi.
When I first tried, everything went on well, I got the image on me TV and I tried to set wireless connections.
But when I was trying, the screen suddenly displayed "no signal", I tried to reboot(just cut the power off)my pi but it didn't work. I tried several other times and checked the connections, but they seemed all good.
Later I searched on the Internet for the solution. I tried some but nothing worked.
Now as I give the pi the power supply. The PWR light goes steady red and the OK light flashes green for a while and then goes out. No other signals at all.
I really need some advice, how can I get image on my TV again? Do I need to change other settings or am I simply better to buy another pi or another HDMI cable? Any idea or solution is really welcomed and appreciated!
PS: I can see the dim ACT light flashing
