Well I'm new with PS3. I purchase PS3 like 2weeks ago. Then i purchase the Component cable and it works well under 1080i until yesterday. But when i start up my PS3 just now the screen goes like shaking and i thought that the Component cable got problem then i tried to shake it. But its still the same. I tried to reset the system like u said by holding the power button. Then it works. However, When i set it back to 1080i then the screen goes like shaking like b4. I even tried 576p, 720p, 1080i all doesn't work like b4. What might be the problem? Do you have any idea?
