Display not lighting

I have a VocoPro Gig Man karaoke machine. Last year the "blue" backlight started flashing on and off and now it is not working at all. I can still read the information in the display if I get up close to it, but there is no backlight to see it from any distance. Any suggestions would be greatly appreciated.

Hi last1975
You will find that the display has a lamp behind it that backlights the LCD display. Changing out the lamp is usually simple enough if you are handy with screw drivers and a soldering iron. Most generally are 12 volt, meter it first if you have a multimeter, You can buy lamps to suit from Farnell electronics in most countries of the world. If you have any trouble matching types to order one, I can help you there. Happy to answer any questions you may have about your job. Good luck, and thanks for using FixYa. 
regards robotek

I plugged in my Nad amp to a socket last night, there was a flash of blue light and now it won't switch on. It is a NAD C316BEE Stereo Amplifier. Can you advise what has happened?


You need only look inside and follow your nose....The smell will lead you the faulty party, probably in the power supply. Just a power surge problem or something that's been going giving up the ghost.

I have a studiomaster powerhouse vision 8 and when i turn it on the displays says ''incorrect pin'', i have never had to enter a ''pin'' and wouldn't know how to, it has worked perfectly for absolutely...


I have just had exactly the same problem with my up-to-now totally reliable studiomaster powerhouse vision 8. It finally let us down at a gig after 15 years faithful service.

Does anyone know how to fix it?

LED light dont come on!!! Pioneer audio receiver VSX-9700s


Do you mean that the display that show the audio source or mode doesn't turn on? Try shining a bright flashlight at the display and see if you can read it. If you can, then the backlight light bulbs have died.

Replacing it will be a pain but you may find a usable replacement at Radio Shack. Just measure the voltage that goes to the bulbs and find one with similar ratings. They are probably 12v lamps.You will need to remove the display from the front panel of the amp and desolder the old lamps. Getting at the bulbs is the hardest part.

Wantind to add mics to my karaoke machine-Vocopro GiGMan karaoke system


I'd get a small mixer, then run mics into that, mix em down to 2 channels then send em to the karaoke machine, that way you have control in mixing multiple mics down to 2 channels, I wouldn't bother with 1/4 " mini plug mics or splitters personally.
A D.I. box ( direct injection ) takes an instrument or line level signal through a step down transformer and it comes out the other end as a mic level signal, the purposes of it are for running an electric instrument into it wich is split into 2, one for going to the input stage of a mic pre, the other can go back out to an instrument amplifier, this way you can run a direct signal into the console via " direct injection " into the mic pre as a mic level signal and also can run it to your instrument amplifier in order to be able to also mic the speaker cabinet acoustically at the same time, there are many benefits to this, for instance in live shows if the speaker cabinet or mic fails then you still have the direct signal, also since the direct signal tends to be punchier and clearer, cleaner, than an acoustically mic'd signal, they can both be mixed together at the console to give a a desired blend of each signal. Since there is a small delay between the direct signal and the acoustically mic'd signal because of distance of the mic from the soundsource delaying the direct signal a bit may be desired. D.I. boxes are only for instruments, they are superflous for vocals, the quality of the D.I. box does matter and active D.I.'s are the way to go, passives are as they are in speaker crossovers, less than desirable quality. There are also many tube D.I. boxes, generally a D.I. box isn't necessary for running an instrument into a consoles mic pre because most consoles take line level inputs as well, and there are other ways for getting a line level signal into a console by bypassing the mic pres anyways, If you have quality mic pres it's good to use them for the initial gain stage though as opposed to boosting instrument level to line level using a crappier preamp, for instance running an electric instrument input through an effects pedal will raise the instrument level to line level but of course an expensive mic pre will do a better job of it than an effects pedal will, since the first gain stage is paramount to quality......................

Add additional mics on the vocopro gigman all in one system


Putting spliiters on the input of a Mic priamp to connect to Mics to one pre is a bad idea. There are lots of techy reasons why, but the short version is "Don't Do it"

So how to solve your problem..


If you have a spare Line input you could buy a cheap external mixer, which will take the microphones and provide an appropriate level signal to your machine.

Something like this ought to do it..

If you have no line inputs, then you can use the output of the mixer into a DI Box to match the levels and use your exisiting Mic ins.

http://www.guitarcenter.com/Behringer-DI20-Ultra-DI-2-Channel-Active-DI-Box-Splitter-182481-i1125215.gc

DO NOT CONNECT THE LINE OUT FROM THE MIXER TO THE MIC INPUTS WITHOUT A DI BOX!
