Anycubic Photon Printer Owners 造訪社團 » LCD

Hello all. I have this black spot UNDER my LCD. It appears to be resin but I am not sure. Can I just scrape it off or do I need to replace the LCD? And, what kind / brand of tape do I need to secure it? I live in USA

So this is what my Photon does.

For the brains trust, I have tried the following to fix it and nothing helps.

Checked LCD connection to motherboard.
Three different sets of firmware. (V4.2.18 currently installed as per advice)
Three different slicer programs.
Four different USB sticks.

I have submitted a support ticket with Anycubic and got sent a link to the bed levelling tutorial. (Handy. Thanks guys).

Has anyone encountered a machine doing this?

Interesting observation to share. Two print beds (each was two legs and an arm). Left side failed, right side successful. Printed one after the next (failure first) with only one variable changed - the FEP sheet. The FEP sheet (pictured) did not have any dents or holes--but had a little wear area that felt rough. Was not possible to clean the wear area even soaking with IPA, etc. You can see in the print where the wear area was the portion that failed.

I think it is interesting because when printing we have a lot of variables to consider--but this is an example of a specific FEP-related failure. I had an inkling it was the FEP because of other prints having problems and I keep two vats ready. But one could have also chased down a lot of other issues like LCD failures, some kind of problem with the file/supports, build plate leveling etc. This was just a little wear spot on the film.

NOTE - this is actually "non-fep" from epax. Which, other than this strange failure on a two week old sheet, has been working pretty well.

How long should I expect my LCD screen to last?

Hello and happy new year to you all! I have an issue I'm hoping the hive mind can help with. A while ago, I posted that my printer quit working. Figured the LCD took a dump, so I replaced it. Still no. Replaced again. Nope. So I replaced the motherboard twice as well. Just put it together. The pictures show what I see as I tried to print something. Any ideas?

Hey guys, was doing great with my printer but I've got a new problem. It seems that now when I do prints, half the lcd or UV light will stop working. Anyone else had this problem and know of a fix? If I switch the machine off and on again the full exposure is working but of course when I start the prints half of it fails after some time.

Well, you can't see it, but there is a 5 inch crack on the screen going from about 2 inches to the top left and swinging a hard right over to about center of the right side. Some UV light dispersion happening, I got it and a new screen has been ordered. For future reference in my mental tome called "What's this?", my question to you is this:
Is the flickering that can be seen in the video normal, or is it another symptom of a done LCD? To me, looking at it in person, it almost looks like it is revolving on a cylinder.

Hello! I would really appriciate some help. I had a ripped FEP foil a year ago and the resin somehow got between the lcd and it's screen, so it started to print holes.
So I bought a new LCD. I own a photon, not photon S. I bought 4 of this LCD-s and none of them worked. So the last one was an LCD for photon S, the test worked but nothing got printed, now I bought one for the normal photon...the test is just a whole lit square, and if I try to print something I get: LCD Error code: T_100 L_40.
Please can somebody help, I'm really loosing my mind here :(

I bought an any cubic Photon early 2018, but only just unboxed it now. Assembly went well, but the LCD test doesn't display the rectangle, I've reseated the LCD screen cable, and upgraded the firmware, but it still doesn't display the rectangle, and if I try to print I get a T_800 L20 error. Any ideas what I am doing wrong?

Photon S - LCD life time/power output

My printer prints about 8 hours everyday. I can not find a definite source for the life of the photon LCD life. I want to preemptively change the LCD before it reaches below maybe 80% of original output. I am afraid my LCD will be weakened from long term use and produce insufficient cured parts to my customers.

Based on your experience, when do you change your LCD? Does it work great and just suddenly break, or maybe it slowly degrades?
