Hello everyone. I am new on the forum and had a few questions. I just took over my church lighting duties and have been told that they have had 3-4 Cyber Paks go bad. Well, another one just bit the dust today. The led display is very weak and the lights will pulse on and off at any setting if it turns on at all. The unit may come on after a half hour warm up period if were lucky and may allow a power on up to 30-40% brightness. My main question is this: What do I need to look at to repair this unit. I can tear it down and troubleshoot if I need to. I am looking for a power issue I would assume (bad capacitor), or maybe the transformer? Is there a schematic I could download or buy? It seems these units are not that old. They range from a couple of weeks to about 5-6 years. The lights controlled are on an average of 2-3 hours a day 3 days a week so I would not think these units are "abused" or overloaded ( they run 3-4 lights each using 300 watt bulbs). With the economy the way it is I would like to be aboe to fix it(them) instead of the church having to scrounge up $200 + each time one goes bad. I do appreciate any and all suggestions and help offered. Have a great day!

Hi Cypher and welcome to the forums.

First, sounds like it may be a power issue with the pulsing. If it is the packs, seems like you are on the right track with a capacitor issue.

Second, I would give service a call. They would have all the diagrams and be able to help you troubleshoot. Just make sure you have the pack/s in front of you when you call them. Also, the ones that are only a few weeks old should still be under warranty, so they can issue an R/A for service.

However, since the ages range from years to weeks, I would assume its more likely a power issue within the building. So my question to you then is how are they receiving power? Each one have its own 15/20 amp circuit or doubling it. Pulsing lights is generally a sign of voltage drop. Any sound gear on the same outlets/break box? When the amps hit big notes, general low-end, they draw more wattage which can cause this effect. I have seen it become so bad before, I have witnessed the effect in LEDs as well.
To reinforce what Serra Ava says(and he's a lighting guy and I'm a sound guy), sound and lights should ideally never be on the same circuits. Both have very different requirements.

I would start with Serra Ava's advise, but also what are you pushing with the packs? This may reveal a current draw situation. It's not 100% true that each pack should have its own circuit or not, but that depends what you're turning on/off with it. It is a good rule to adhere to though: 1 pack/circuit.

I think something along the lines of poor utilization of house power through an improper wiring plan. Electric should be done by an electricianl, but should be done under the guidance of the lighting or sound or AV techs so it's understood what needs to be where and why.

Call support, have a screw driver handy, good work lighting and be prepared to be very descriptive. You're going to be their eyes and ears over the phone.
