My lexicon mc 12 pre amp won't power on. The lead


There may be a secondary fuse inside the unit, if not the problem will be in the power transformer, if you are handy with a digital post back and I will give instructions on testing the transformer.

Hi, I'm not sure of the polarity of the Lexicon mx200. I have bought a multi tip transformer & it gives 2 options of outside + or inside +, do you know which is which please, I don't want to fry it!...


DO NOT use universal adapters to run these devices. Accidents are too easy and often the universal devices do no have adequate filtering. You are off on the wrong foot to start with as this unit does NOT have a polarity since it REQUIRES an AC adpter, not a DC one. What you have WILL NOT WORK. If you have connected it, it should NOT have caused damage, you just won't get any audio out, even if the unit lights up on one polarity. The unit generates both polarities inside using the AC input.

Here is an example of correct adapter: http://lcdpayless.com/productpage.php?productId=5793

Whats the polarity of lexicon ionix u22 audio adaptor? should i set plus or minus polarity on the adcd transformer/adaptor? thankx


Easy answer: You DON'T set the polarity because this particular device takes a 9 VAC at 2.1 amp adapter. (Not a DC one like so called universal ones)
It sounds like you have one of those universal adapters which probably would not deliver the 2.1 amps required even if the lexicon took DC. Note that stuff might light up, but the unit will not work using a DC adapter..

You had better get an official power supply for this unit as what you have will NOT work, period!

I did a quick search to try and find a link to a supplier, but they are RARE !!! Every one I found would require you changing the plug to match the Lexicon.

You should just order the correct one from Lexicon.

Need diagram/schematic for Lexicon MC 1 power supply


As far as I know, Lexicon schematics are only available to authorized service centers. Can you describe the problem that you are having? Perhaps we can assist you with the repair?

I can turn everything on but the belt does not move. I used it one morning and then that evening it would work


The single most cause of no motor output is failure of the DC motor control. Before you attempt to determine if it is the control, you must first rule out simple things.
1) Make sure you have power in the wall outlet by plugging in a lamp, etc. into the same outlet the treadmill is plugged into to test. Plug it in the exact same receptacle. Sometimes in an outlet one receptacle will work and the other won't.
2) Make sure any breakers are fuses that may have tripped or blown have been reset or replaced. Your local Radio Shack can help you test the fuses. Use the same type of fuse. Changing the value of the fuse can be dangerous or cause a fire.
3) Make sure the power switch is turned on and the safety key is inserted into the console if you have a safety key.
4) Look for any test lights on the power boards beneath the motor hood. Use caution when removing the motor hood because you may still have electricity in the motor area even if the treadmill is unplugged.
5) Test for a motor control failure. Typically if you have a failure, the treadmill will continue to turn on and operate normally until you try to input speed. If the treadmill operates on what we call a closed-loop system, it will give you some type of error message. If it operates on an open-loop system, the computer will run normally but the motor will not turn.
6) If you have a multimeter, you can test to make sure you have DC output from the controller spades. First make sure you have 120 VAC going in to the controller. On most controls, you can use a linear taper potentiometer or jump the W and H circuits of the control with an insulated wire or insulated pliers and apply AC voltage. The DC output spades should output DC voltage if the control is good.
7)
Cordless drill battery- get a fully-charged, 18 volt (preferred) cordless drill battery and on most treadmills connect the red and black motor leads to the battery (some have different colors but if you have two wires and get it hooked up backwards, the motor will just run backwards and won’t be harmed). If good, the motor should operate at about 1 MPH

Lexicon DC-2


DC-1, DC-2 an MC-1s have the same power supply. The power supply usually lasts about 5 years before it goes. A New power supply is usually about $ 65.00. There is usually a $300.00 LABOR FEE. Check out THE SERVICE BENCH in MA. Phone number is 781-769-4338.
