JGAurora A5S Makes beeping sound and screen doesn't work

luz0928

Hello,

A few days ago I started having problems with my printer, when I turn it on it makes a beeping sound and nothing else happens. The screen doesn't work and you can only hear the fan turned on.

What can be causing this? I've had this printer for a couple of months now and this is the first time something like this happens.

Thank you in advance for your answers

Welcome @luz0928 !
 Personally, I’ve never heard of this problem before. Without the screen it’s also a bit tricky to troubleshoot!  

 I would suggest trying to contact JGAurora, they would be the best people to start with.

Did you ever hear back from the company on what it was? My printer started doing the same thing this morning. Long beep, no display. Wont do anything else?

Follow up: This was diagnosed as a mainboard issue by jgaurora support and they are sending me a new one. Will update once i get it installed and tested.

this similar issue just started to happen to me.

but it happens a little  bit of time into the print. 

starts beeping very loud. white screen. very annoying

Could be the LCD having the issue. Maybe the 5V regulator on the main board is having an issue too. If you hook up a 5V adapter or something to the USB port, does it work? Just one more thing to try I guess.

@mikemullaney1320 because the motherboard is proprietary, I would suggest to contact JGAurora. Maybe even send them a video of the problem when it occurs. It is not something I have seen before.

What do y’all think? Literally just happened and I didn’t have my phone.. 45 mins into print

Yeah, "maybe" is not good enough. These boards do not overheat under normal operation. If they were that poorly cooled then I would NEVER recommend them to anyone. Even if it was overheating... 45 minutes in to a print, that's ridiculous.

that's hillarious - the response is like what a bot would say if I used troubleshoot.keywords=beeping/fan/screen doesn't work

the response of "remove the fan wire" is absolutely fabulous

- I guess you could try unplugging the fan and turning it on without it connected (make sure you unplug the unit if you go in there - even the USB) then if it works,  plug it back in and try again

Electronic cicuitry is not my thing, but I understand the idea that the fan could cause an overload.  Cheap fans go bad easily. 

Maybe they think it's just overload protection and they want you to check to see if your fan is causing it.

Thanks @giantrobot2001 - I think I understand now what you think he was suggesting. If I was him, I would start with "are both of the fans working correctly" or ask, "do the fans feel very hot?".

Yes, something lost in translation - I think he is suggesting that the mainboard could be overheating and becoming unstable - and that you could fit your own blower fan inside the controller case to cool the controller board down

There are components on the controller board that can get hot
