I just bought Leadsinger LS-3700 from Walmart and tried to connect it to my Plasma TV.

I connected it to DVD port. I can hear the audio but on the plasma screen it shows No Signal.

Any Suggestions on how to fix this problem

Not sure, never used that little system.  Does it work with any other tv?

Well being as it's pretty portable, I would take it either to a store that you can test on one of their tvs or a friends place.   It may have a bad video output on the unit itself.

Some TVs have to be on Channel 3.   You may have to use the menu button to use a different video input.    Leave it on each one for a little while so the signal has time to get through.   I have the issue on one of my bar TVs.   Takes a few seconds before it appears.    You may need an RF moduator to change the signal.   You may need a PHD in electronics... LMAO    The hardest part of doing karaoke is getting the TVs to work right. :yes:  :O  :shock:

If it's using a RCA video output - which it has, then most likely it has to be set on the proper video input & not channel 3 - that is a 75 ohm antenna/cable input.

Most LCD and Plasma TVs these days have RBG connections in addition to traditional RCA Audio/Video jacks. You may be trying to connect your RCA Video from the karaoke player into an RBG DVD jack on the TV.

Everything should be color coded. Try connecting your red, white, and yellow cables into a channel other than the DVD channel and make sure everything matches up color-wise. YOu may then need to select a different INPUT channel on your TV using the SOURCE or INPUT button on the TV or remote...
