hi Ian, If you want to PM on the address below with the desk S/N and what you are seeing as the desk boots up will see if i can help on this one.

Drop me a PM on this for he circuit info. And yes the initials on that label are mine, 😀

Hi Chris, Checked on this and the switch setting on this PCB should all be in the off position on that PCB. I am unaware of of any issue with 4.1 in regard to LCD stopping working but if you have carried out an update from a much older version of the firmware this has added a LCD calibration function into setup to compensate to changes to the LCD's. There are two options a high or low try changing between the two and see if this brings the display back on.

We did at one point have a IR remote in the range but it was discontinued a number of years ago now. Not sure about the universal remotes as they are geared towards TV, DVD etc, but if the information i have is correct try RC5 group 30 as the pairing option.

Hi Craig, Believe i was talking with you at the end of October with regards to this. think we got to the point where we though it was the keypad cause the issue. From our mail trail, I offered to have a look at it you could send the card set back to me, but don't think that happened or if it did it may not have been direct from you as i cant see any further conversations. If you want PM me we can follow up on this.

on these there are ramp adjust pots on the back of the keypad PCB, it sounds like these may be set to high. the way we set them on the bench when building the units was turn preheat on and adjust until you get between 11-12v ac showing on the output. PM me for more details.

Hi Peter, Try checking the contact on the battery holder itself. There is a contact in the base that can become tarnished so does not give a good connection. it can also become bent down so does not make contact. Gently bend this slightly may help. PM me on the address below with the serial number I can work out what version of hardware the desk is running.

From memory the frog section will not do anything until select a fixture, if the desk is defaulted then there will not be any assigned. Do that first from with in Super User, there should be 20 already in the desk by default. Once that is done when you select the fixture it will activate the reset of that section.

Hi Bert, it is possible that if the dimmer is one of the very first models the Alarm option may not be present on the unit. When you power the dimmer on you should get the firmware version show on the display. Please PM me that on the that the address below and I will check the notes for that version.

Could you pm me on the address below with the units serial number we can take it further from there. Also have you tried to connect to an external monitor and see what that is showing?

Don't normally see that message on an ML desk. It would indicate either attempting to load a show file saved on desk running an older show file or the show file has become corrupted, possible due to a flat battery. Pressing enter should remove the message and allow the desk to operate as normal. If you have loaded an old show then save it under a different name and reload it to cover it to a 4.1v. If its a battery issue check the date and time as this will have reset to a much older one.

Hi Kevin, Have also replied to you mail to the address as well. Please see the link below for the work around.

Hi Ondrej, I believe you have also emailed my colleague Franck Tiesing as well on this. He has forwarded your mail to me. I will make a reply direct to you on this.

the LTC tended to have a built in DMX unit, should be a keypad with a display on the top left of the rack. This has an internal battery that could have failed and is cause the issue that you are seeing. PM on the address below an I can talk you through what you need to look for. Regard Keith Rogers keithrogers@eaton.com

Yes the 100k resistors or the 10uf cap either failed or a dry solder joint on it would be the first place I would start looking at on the mk1

Hi Steve, Please see the attached fixture. it contains the 3, and 15 channels versions. You have not mentioned which desk this for but if it for one of the Zero OS desk then you may find it easier to control but by actually splitting this into four separate fixtures with consecutive DMX addresses. To aid in this there is also a set of four profiles one called master, then pod 2, 3 and 4. You can then set up a group that would allow select the whole fixture quickly. 4 bar.ift

Based on the serial numbers, all the dimmers have 2006 manufacture dates, think it is more likely that a component in the phase detection circuit may have started to break down. For the ERR that sounds like a communication issue between the power PCB and the keypad, could be a link cable problem. For the flickering channels, have the packs been serviced during their life span to check for loose spade for the coils, creep on sockets connections etc? For the transformer issues that you have mentioned, the symptoms associated with this are different to what you have described. Our investigations have shown that this was limited a small batch of dimmers manufacture between late 2014 and early 2015. PM me on the address below. It is worth getting one of the "preheat" dimmer back to us for assessment we can confirm what the issue is. Also can you confirm if the dimmers are running on three or single phase supply.

Could you PM the on the address below with the serial of the desk and a copy of the CFT file as well. When you say the desk is not responding do you get any information on the displays or VGA output?

assuming this is a jester 12/24 or a 24/48 then this may be to do with the age of the desk. the early revision (R1) motherboards did not support keyboards. If you go into super user, you should get the desk type and version of OS it is running on, serial number and on the new version of the PCB it should also say R2. if you PM me the s/n i can work out the age and let you know if it a R1 or R2 version if it is not displayed.

From the information that you have given it sound like DMX receiver has failed. these are surface mount parts so would need to looked at to replace them. if you PM on the address below with your location I can point you at your closest service agent.

sounds like the identifier switch on the back of the preset PCB may not be on the correct position. PM on the address below to take this further.

Hi Peter, Hi Peter, I assume you did not get my reply to your direct from Monday. As Ian said this is something we have come across and the easiest solution is to replace the power PCB. If you can PM with a full address will make the arrangements to send you one for your service man to fit.

No it is not possible to limit the max channel value with the fixture edit tools.

Hi David, As Jon has said it is looking like a hardware fault. Would need to see the desk to be able to confirm 100%. PM on the address below to discuss the options we have on this.
