When I sing using YK5000 Karaoke ( Kortek magic Mike ) wireless mic using LG LED HDTV - I experience delay of up to 2 secs . I tried the audio settings (standard ioption in LG audio settings)

Ok..I found a workable solution. Essentially using my HDTV only for the lyrics(video output) and using a RCA to stereo mini plug cable to send the sound output to my amplifier that has a analog stereo input. Works like magic. No delay. It went from being unusable to WOW!

i bought et18k. just the same as yours.its 2 days old and has the same problem. the technical assistant says that its because of the digital setting that new tvs have. there are two ways to solve this though:

1. connect the video (yellow plug) to the tv. and the other two plugs (yellow and white) to the stereo. when i say stereo, its not the dvd home theater system that you have but a separate one. if you connect it to the home theater that you have, it'll just sound the same, you still have the delay.

2. connect the magic sing to the older tvs hangin out. and you'll get no problem at all.

**TVs such as sony, samsung, philips, sharp and all plasma tvs including other newly designed tvs will have the delay since they all share the HDMI thingy that causes sh*t.
