Question 1

I used bluetooth to connect my ipad to the receiver, the used hdmi to connect the receiver to my tv for speakers but no sound at all. what to do?

Accepted Answer

The hdmi doesn't work on this machine and it seems to be a common issue. In general, the best way to send sound in and out of this device is analog aux cables

Question 2

How do you get mic audio to portable wireless bluetooth speakers (wonderboom) that are themselves bluetooth connected to an ipad (for youtube music)?

Accepted Answer

BT devices are either receiver and/or transmitter
in your case:
wonderboom is a BT   receiver only
portable karaoke is a BT receiver only
iPad is a BT transmitter only

thus, to use the portable karaoke  with the devices you have, you need a BT transmitter which you can buy from amazon.
pair the BT transmitter with your wonderboom speaker
once paired, plug the 3.5mm connector of the BT transmitter into the poertable karaoke audio out jack
pair your iPad using BT with you portable karaoke

needless to say, power up everything and test. you should hear all sound inputs through your wonderboom spekaer. play your favorite youtube karaoke on the iPad and use the provided wireless mics. ENJOY!

Question 3

My microphone stopped turning on, seems due to the button on the circuit board. Do you sell replacement boards?

Accepted Answer

You will have to email the seller about that. Or just take out the circuit board and solder the on/off switch to permenitly ON...  just a thought

Question 4

Can the video from the TV be output to the mixer using HDMI?

Accepted Answer

I don't know any TV that can output video via HDMI.  If you're asking if you can output from another source (like an XBOX or a ROKU stick) then yes you can output from that into the mixer and from the mixer output to the TV.  
Usually though, people would output sound from TV via HDMI ARC or an audio 3.5mm cable and to the mixer, and from the mixer to an external sound system via 3.5mm cable.  We found usability issues using HDMI arc so we use 2 3.5mm cables instead.  Analog seems to be the most reliable.
