How do you get the blue LED to come on? I'm unable to get it on, and so are the other folks who posted on Amazon. Did I get a bad one or is there something missing in the instructions on Amazon? The unit itself came with no instructions. How do you get the blue LED to come on? I'm unable to get it on, and so are the other folks who posted on Amazon.

What difference does it make, as long as you can adjust the two screws to produce the correct DC current up to 12 volts. This item was not designed to produce a light show in blue.

The blue light will come on when the current limiter is adjusted close enough to the voltage setting to see a significant load. It did not operate until I tried to take the settings for current out of accordance with ohms law. I didn't play with it long enough to figure out exactly at what load vs voltage it came on at. I do remember it activated with a 250ohm load at 9.4v when the left adjustment was turned all most full counterclockwise and when I ran a dc motor at 5v and was adjusting the current output. The blue light being off did not seem to affect the operation of the unit. I hope this helped.

Hi, I got one with no instructions too. I know that the middle button turns on the light and if you keep pressing the button it changes color modes. The other two buttons on the outside is volume buttons up and down. Sorry that's all for now.

When the unit is working the light is very faint, but it is also possible that the bulb has blown or the unit isn't working. I would try putting it in the tank, turn off all the lights, and then see if the light is on at all. If it isn't you could try returning the unit, contacting the company, or just buying a new bulb to see if it was just the bulb. I have been using this for a while without any problems. Also, you will only see the blue light in the little circle at the bottom in the front when the unit is plugged in and workign properly. Hope this helps a little! Good luck!

No problem... Hold down the key on the far right bottom that looks like a light bulb, the push the arrow key next to it up till u get to the color u like. Very cool!

not sure...when you installed the battery was the unit plugged in or not? if it was plugged in, try unplugging it after powering it off, intall battery, then try the power buttonwhat happens next? is it just dead or do you get lights at all even for a moment? mine just worked and was not an issue.....did you dbl check the model numbers? and it fits ok, not wobbly?mine has been working like a champ....no complaints at all!!!!

We do not have a copy of the instructions because this item has sold out. Please verify the instructions are for the same model number. Also please try the backlight feature in the evening because it may not be strong enough to see in strong daylight. Thanks.

i havent been able to get the LEDs in my headlights to turn on. Not sure if they just dont work or if im not wiring them correctly some how. The headlights have been great otherwise, just wish the LEDs worked.

Mine did not come with instructions either. I just kept working with it and finally got it. No on/off switch either unless you found one, or I just haven't figured that out. When I know I'm not using it, I pull the batteries out. Otherwise, seems to work perfect, I'm satisfied. Hope all that helps!

@ Getulio L. If you are asking a question.... Perhaps you could elaborate. For example You might say: I've owned the system for 3 yrs, I've never had a problem with it before but this time.... when I .... it didn't work. Then explain the process you used to try to get it to work:. I plugged in the TX card into the unit (with the unit off). I then FIRST plugged in the remote unit and let it cycle through it's power up routine.... if there was a problem there??? or you don't see the blinking LEDs tell us that. After that powers up & ONLY after you first power on the wireless speaker unit do you then plug in the main unit.... So when you did that what happened. You have to provide information & context. Maybe someone just gave you the unit and it's your first time trying it out, maybe you've had it for years and had a a power surge etcetera etcetera etcetera how are we supposed to guess what the details of your situation are?!?

Since this is a powered hub, you must ensure that you have it 'powered up' Mine had a small red LED that lite when it was plugged in. If connections are good, and your LED is lite (and unit still fails) you need another one.

That's what I wondered too, if it needed to "warm up" first, or be in an extra-dark room. You may have a faulty one too like me. I had to tap on it near the bottom & turn it upside down & hold it it at an angle to get it to light up-not what you should do to make it work! Email Amazon & they'll fwd it to Scientifics & they should email you back w/phone #. I called them today & they said Fedex would pick it up next day & send me another one. So hope next one works! Good luck with yours! :)

Our new LN-T1953H has the same annoying defect. Every time we select Blue Light: OFF in the setup menu, it comes back on later. Arrgh! Does anyone know how to fix this?

I never got one of this brand because they were out of stock and wound up getting the one from Poetic. It looks exactly the same - probably all from the same manufacturer with different branding. You have to be a little bit patient. Make sure you have pushed and held down for a few seconds the button to the right of the on/off switch on the keyboard after you have turned it on. Settings has to say it is "paired" not merely connected. When everything is working, the blue light on the keyboard does not flash; after pairing, wait until it stops flashing, then try it again. Hope this helps. I never got one of this brand because they were out of stock and wound up getting the one from Poetic.

Two thoughts first press the red button on the top of the black little box where the power cord attaches to the LED Board. It should come on immediately; unless something is seriously wrong with the board. Then check your remote control open up the battery compartment there may be a piece of the plastic tab still in there or the battery may have come loose during shipping. If you open the battery compartment and there's no plastic in there and the battery is in the proper place you may simply need a new battery. Mine has been up and running since day 1. If none of these seem to be the problem I would return it for a replacement. Good Luck.

Mine came with no instructions but I am not so sure mine is working either. Not so sure any of them work.
