My hdmi ports keep going out. why does this keep happening? i have a 42" lcd flatscreen (philips). I have a PS3 hooked into hdmi port but every 3 to 4 weeks the port stops working and i have to set up an appointment with a tech and all he does is reset it. if i can do this by myself it would save a lot of time and trouble.

If I have the right manual you should connect the wii cable from the package to th backside of the tv. You will see four pluges. Choose with VGA you want to use, this is not important. Use the cable from the wii and plug in two of three pluges, you must match te coulors. If you have a cable box installed you will probably have scart (a big cable with a large head) connect this and it would run smooth. You can also connect the three pluges from the cable to your cable-box, use the red, wihte, and yellow pluge.

you have to first plug in the s-video before you use hdmi so you can set it to HDMI on your ps3 when you go to your setting. Then it should work. If you already did that and it still doesnt work its probably the HDMI cord
