Hi Mandy

Think you have a problem with the cabel or if you could adjust the channel for the correct signal. Maybe the tv-chip on the consol are broken, and you live to far from me for me to help :)
you have any friend who could take a look ?

Best regards

Insert game disk and horizontal lines move fast on screen ???????


Sounds like your TV has multiple video inputs. Make sure the TV is set to the right channel or input. I know on ours if I hit the TV-input button on the tv remote I can change from inputs like s-video, video, cable etc and the Wii only displays properly on one of them.

It sounds to me like you're describing the re-trace of the unit. It is repairable, and more so the sooner you get it to the repair facility.

The set you have has a bad tuner assembly. At this point most likely you would be better off getting a new TV set. Good Luck

do some voltage checking on the ic and make sure that volages are reaching there, about 32 volts. if it is reaching, then you can change the ic there. but before you do that, check around that ic and make sure everything is ok there. good luck
