Litelab Service and Parts
We offer complete factory authorized service for most Litelab lighting controllers. This includes both the logic and
the switching packs. Factory original parts are used whenever possible. We also sell all parts that are still being
made plus we have most of the parts that are no longer available anywhere else.

Complete rebuild of the classic logics, L-4000 and L-8000, is priced at a flat rate of $200.00 plus $10.00 S&H.
This flat rate applies in all but the most extreme cases where a lot of physical damage is present. (Like dragging it
behind your van or pouring a rum & coke in it.)

Work on packs is always priced as parts plus labor. The single biggest expense is usually in triacs. Those are the
silver hexagon shaped things that screw into the heat sink. They have three wires attached, probably black, red
and yellow. They cost $24.00 each with leads. It is unusual to spend more than $200.00 on a pack unless it has
been on fire.

Our normal turn-around time is "same day" but be sure to call if time is critical. Only one tech works on these and
he is often on the road.  
Frequently Asked Questions
The following answers apply mostly to classic logics and triac packs with a pull-out disconnect. We work on other models but online support
is not available.

(FYI - Plug in the ribbon cable backward and you will burn the ULN2003 chip in the logic every time. You will also sometimes melt the chip
into the socket. Usually there is no further damage.)
A few words about servicing your own equipment
SAFETY * SAFETY * SAFETY
Do not attempt to service a driver pack unless you have general knowledge of electrical service and can use a VOM or DMM. Never
work on a pack unless you are sure that the power is off. I always check all of the incoming lines with a voltmeter before starting
work. Pulling the disconnect is a good idea but I have seen several cases where someone has wired around the disconnect.
Nothing works, not even the power light.
1. Make sure you have power to both sides of the disconnect and that the ribbon is plugged in.

2. Check the fuse that is in the corner of the pack next to the three large gray caps.

3. Check continuity of the logic power switch.

4. Check ribbon cable for damage.

5. Power supply in pack probably has problems. It's a pretty simple power supply but a pain to get to.  Generally, I just pull the
board out and replace everything.

One or more channels, hot or neutral, are locked on, sometimes even after I shut off the switch.

1. This is almost always a bad triac. You can check by removing the yellow wire (white on later models) and turning on the
Immediate damage will result. When the display is an inductive load, such as pin beams or neon, we always replace the triac
and opto as a pair. A triac that has come apart from it's base should be replaced, not superglued.

One or more channels, hot or neutral never come on or come on at reduced brightness.

1. If it is a hot channel, check the fuse with an ohmmeter.

2. If it is a neutral channel or if the fuse is good, check the opto and the display wiring. The opto is the little gray chip below the
triac. Just swap it between two channels and see if your problem moves.  Don't put the opto in backward. Refer to the dimple in
one corner, not the writing.

Slide pots on the logic are erratic.

1. Spray with Caig MCL, nothing else. That means no tuner cleaner. If you can't find it, call. We sell it. If that doesn't work
replace the pot.

I keep blowing 10A output fuses.

1. Your load is too great. Have you changed to higher wattage lamps since the system was installed? If you have an inductive
load (such as pin spots or neon) the problem could be more involved. Call us.

My sound system hums when the lights are on.

1. Reverse the audio leads on the back of the logic.  (Or maybe it forgot the words to the song.)

My pack was on fire. Is there any hope?

1. Absolutely, but it depends on how bad the fire was. What burns are the square yellow caps, and when they flare they
produce a lot of smoke and soot. Most of the time it just soots up the other parts and really doesn't hurt much. Other times, I
have seen it burn a hole in the board the size of a silver dollar. Either problem can be fixed, it just depends on how much you
want to spend.

NOTE:  CHECK YOUR PACK.  IF IT IS A TRIAC STYLE PACK WITH A PULL-OUT DISCONNECT IT MAY NEED IMMEDIATE       
                SERVICE!  DISCONNECT THE POWER, REMOVE THE COVER AND THE INTERNAL SHIELD OVER THE                   
                ELECTRONICS.  EACH CHANNEL HAS A CLUSTER OF PARTS JUST BELOW THE TRIAC.  IN EACH GROUP            
                THERE ARE TWO, .01 MFD CAPACITORS.  THEY ARE SQUARE AND ABOUT 3/8" x 1/2" x 1/4".  IF THEY ARE         
                YELLOW THEY NEED TO BE REPLACED IMMEDIATELY.  WHEN THEY FAIL THEY CAN FLARE AND OFTEN            
                DAMAGE THE PC BOARD SEVERELY.  CALL IF YOU HAVE QUESTIONS.

Will you sell me prints?

1. Blueprints or schematics are the property of Litelab Corporation. We do not distribute them in any fashion.

Can I get live telephone support?

1. Yes, our technician is available for live troubleshooting M-F, 9-5 CST. Please be at a phone that is within reach of the logic.
Cost is $1.00/minute billed to your VISA/Mastercard. Time starts when you reach the technician. Our Litelab technician has
been working on Litelab systems since 1978 and services Litelab logics and packs every week. Most pack problems can be
fixed over the phone if you have general electrical knowledge, a VOM or DMM and can solder.

Can I buy replacement or additional equipment?

1. Litelab has not produced any of this equipment for many years. We have rebuilt packs and logics available quite often.
Please call or email for availability.

What products do you support?

1. L-4000, L-8000, L-1000, L-4001, LCE-445, LCE-440, all 4 ch packs, all 8ch packs, SmartAdvantage and beacons.

2. We also service or support all products we have ever sold including Electro-Voice, QSC, Mackie, VEI, American DJ, Shure,
EAW, Lightcraft, NSI, JBL, and many others.
