Hi, you question is directionless, what product are you talking about and model is it. You have to provide these information for me to ba able to answer your question...

Take care

same problem :(

We had this problem too. Can you perform any functions with the duet mic? We couldn't, just had the light flashing. Turns out the light is supposed to flash (never is solid). Check the connections to the sub mic pack in the back of the main mic. Ours was loose. Once that was plugged in properly, we turned everything off and started again. All was fine.

Good luck.

I removed the cable from microphone circuit board  and shortened cable by 20 cm. to eliminate damaged wires, stripped the individual wires and soldered the pins to the new wire ends and reassembled.  Used black heat shrink tubing  [10mm dia.] to reinforce cable end at mic to prevent future damage from careless handling.

Document wire colours to pins before disassembly

I removed the cover on the back (the access to musicartridges) I also removed wireless receiver unit (approx 2" black plastic piece) pull straight up to remove. after removing the receiver you'll see two screws, remove them, unscrew the mic head, pry the body apart (fingernails). You will see two circuit boards, the smaller one became disconnected. The board should reconnect easily, the outlet looks almost like the wireless receiver outlet you removed earlier. if it does not slide in easily DON"T force it, you may be trying to install into receiver outlet ( They look the same), The correct outlet is above (towards mic head) the four outlets to the music cartridges. CAREFUL NOT TO BEND PINS same with the wireless receiver.

look and see if the RF light is coming on, if it is not then the transmitter (mic) is not on the same frequency as the receiver.

Contact Leadsinger directly to request the manual for model LS3700W.

My suggestion is to hook up a laptop then use a slide show builder.

I found a power adapter at the local thrift shop for $1.99. not the original one but it works fine. AC adapter Input:120VAC OUTPUT: 9VDC. good luck..

no there are various issues , model of the system the make ( magic sing will fit magic sing ONLY ) if laungage font is different example hindi etc then also it will not work chips made for very old models may not work on new systems example ed series chips may not work on KV and KH series for more please email me on [email protected]

Unfortunately you have bent the contacts which connect to the SD card. The only solution is to dismantle and attempt to re bend the contacts back to their original shape and position. This should be done very carefully as any excess bending will snap the contacts.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
