Martin Quantum Profile error

[Rafael33]

Hi to you all,

 

I been experiencing the same issues with the Martin Quantum profile. I work in some Theaters with Quantums, used in daily basis, cleaned and filters exchange in regular basis.

After 1 or two years usage several start not output light after a few min usage. The most common error is BETE error.

Anything I can do to avoid having this issue? What to do to fix it? Replace the LED PCB is quite expensive.

Expected more from this expensive piece of equipment.

 

Any tips or advise will be much appreciated.

 

Best regards

BETE is a beam temperature sensor error. There is a separate error message for an LED temperature sensor error, so you shouldnt’t need to do anything to the LED PCB since you aren’t getting that error.

 

I do not know the fixtures in question, but the beam temperature sensor is probably on its own separate PCB, so should be easy to identify and test. If there is nothing wrong with the sensor, then have a look at why your fixtures are getting too hot. You are cleaning the filters, but do the fans actually work correctly? Are the fixtures positioned somewhere that gets too hot?

The fans are working properly and they are not positioned in a place where they can get too hot.

Martin advise me to either replace the LED PCB or the color engine.

I found it weird. I guess they just wanted me to order expensive parts.

 

Thank you for the advise.

Or maybe they just know what the problem usually is, given that they make the fixture and deal with its faults every day. I don't think I've ever had advice from a manufacturer tech support that is motivated by parts sales, Martin or any other. A lot of standard advice for fixing modern LED units is gonna be a PCB swap rather than component level fault finding in the same way that a car mechanic no longer overhauls assemblies but rather swaps them out for whole new ones. I do work at component level, but in order to get working fixtures back on the road in a reasonable time there is a lot of board level swaps, leaving dead PCBs to be fixed during downtime. If you ask a manufacturer service tech what they do, you'll usually get a "We just swap the board." answer.

 

As it says in the user manual that the BETE is a sensor error, not an actual temperature error, then presumably the problem lies in the sensor circuit somewhere. This could be anywhere from the sensor, all the way back to the processor. You could hunt down the fault and attempt to rectify it at component level, depending on skills and tool availability but this comes at the cost of time and the risk that you may not be able to find/fix some tiny issue. However, a lot of the time it's more cost effective for a business to just swap a part out and move on.

 

If you want to verify the fault and Martin's advice, then swap out the parts they suggest with known working ones from another fixture. Then you can assess if you want to buy a new part or use a donor fixture etc.

 

I started a series about this recently: http://www.onstagelighting.co.uk/lighting-equipment/led-moving-lights-service-and-repair/ and http://www.onstagelighting.co.uk/lighting-equipment/chauvet-r2-wash-repair-maintenance/. When the next in the series comes out, it will outline a method by which you can avoid buying an LED PCB costing hundreds of pounds, just to replace a single R2 Wash LED chip. Obviously, that isn't gonna fix your Quantum Profile but all these topics are highly relevant at the moment, and the reason I've started the series of articles.

Does anyone know how to take the bottom cover? I got the parts and want to replace them but I cant take the bottom cover or the back cover. All the screws were removed and if I force it too much I will break the cover.

Martin didnt do a good job with this fixture and they crazy expensive. Was easier to do service on Robe. Thanks in advance.

[the kid]

I have done a few times If I remember right

1 - it is a bit of force to take off

2 - there are quite a few screws and I want to say you need to remove the handle 1st but I might be wrong.

Hi Rafael,

did you manage to get this fixed? I have a ton on quantum’s with this problem..

TIA
