Ah....... the joy of getting resin leaked into your LCD screen
I'm more shocked that I haven't cut myself(yet) more than the leak itself lol

hey folks. its been such a long time that i had a photon i could turn on, how many beeps should there be when you switch it on. I'm getting four loud beeps. also the new mobo came with the latest firmware upgrade but the lcd test all I can see is the lights underneath.

TL;DR - Anycubic sent broken printer, looking for troubleshooting tips on not powering on.

Ordered a photon from Aliexpress, tried to cancel 2 days into 5 day processing. They said they couldn't, then shipped it. It showed up the same day as the one I ordered from Amazon. Showed up very blatantly used and abused, in non-factory packaging. I opened a dispute and their immediate message was asking me to remove the dispute. (lol)

I decided to take a closer look at how bad this printer was they sent me pre-owned, and I can't even get it to power on at all to inspect the LCD. I've swapped power supplies (which are also different) between the good and the bad, with no change to power.

Is there any quick/simple troubleshooting to this power problem? I'm just looking for a very detailed complaint against the official Anycubic Aliexpress store sending me a used, damaged, non-working printer at $10 more than the NIB I got from amazon.

Hello photonsters,
A couple of weeks ago I was made aware that are printers were having some failures. Are printers have been running for about 5 months now. 8 to 12 hours a day Monday thru Friday. So I went through all the basic steps to try to trouble shot the problems. When I did the UV test the rectangular on LCD screen didn't look clear. It looked cloudy to me. My thought was LCDs were bad and need to be replaced. So before i did the LCD replacement. I text Vinicius Silva and asked him, Can i replace LCDs and reuse protective glass?" LCDs looks cloudy when doing UV test. I think they need to be replaced. I'm no expert so I thought I would ask a master.
Vinicius replied, What do you mean lcd is cloudy?
cloudy is not a objective term i'm afraid ?
Please share picture.
Funny guys these master photonsters. Lol.

So long story short
We had a dust problem (a bad one) and not a bad LCD problem. They saved me from doing a LCD replacement. Plus i gained a lot of photon knowledge out of all of this. Thanks again.!

It was much easier to air off and clean inside of cone and back of LCD then to replace LCD.

Oh i disconnected the cable from the 3.5 front screen in the second printer. Then closed it up not knowing till you turn on to check. Had to re-open and reconnect cable. ? Never stop learning!
so here are all the videos and pictures that I shared with Vinicius Silva and Sun Kun throughout the process. Now I'm sharing with all photoners. Keep an eye out for the dust build up! Thanks again!

Does anyone know what the part is called or if I can source the small black plastic clip thing that holds the LCD ribbon cable to the contacts is?

I was repairing the z-axis and the black clip fell off the connector ribbon. Now we can't find it. It doesn't seem to be in the printer anywhere that we can see and we can't find it on the workbench or floor.

you know if you can downgrade the firmware 4.2.12 or if you can "reset" with the factory settings, I do not work LCD and I assume it is because of the firmware or at least I would like to do the test

Where's the best place to get a new LCD for the standard Photon?

Hello everyone.

So i was hoped that Anycunic will resolve my problem or at least find a compromise but seems that i had too high hopes for them.

Situation: my Photon worked for almost 5 months fine, but closer to November i encountered random restarts during print and soon enough my Z-axis driver was dead. I contacted support 1st November. At 7th of November they've sent me spare motherboard. I thought that problem with my MB so i was glad.

Well - no. Situation was not resolved and Z axis died really fast this time, so at 4th of March i was already speaking with Anycubic support. Asking them to help with restarts problem, they have told that we need working motherboard first. I told them that new motherboard is not a solution to restart problem. Another 20 days of delivery - another motherboard and no luck - restarts are still there.

Since than every day i communicate with Anycubic, tested all of methods they offered. Insulated it everywhere i could, tried different firmwares, switching USB sticks, tried different power DC. No luck at all. At this point, from 10 months i own this printer 5 months it doesn't work, and anycubic did not responce to warranty prolongation.

I want to send them printer and take a refund , but they keep telling me that no way they could do that. I wasted lot of resin, alcohol, other consumables on cleanup after fails, changed FEP films cause too many fails and assembling / disassembling printer.

Anycubic is willing to change my LCD display to "solve" this issue. I can't see how it will help, but anyway soon my warranty will end , and waiting for another 20 days of shipping and not be sure it will resolve my problem is really bad.

I also tried all known community methods such as increasing Vref etc... Still same restarts...

Situation is also complicated as support is answering maximum 1 time per day.

I don't know what i can do and what i should in this situation.
Printer was bought at AliExpress.

Dry prints goes well all the time, but as soon as i set VAT with filled resin ( doesn't matter which one - tried anycubic green also), printer fails at random place. Here are videos i have:

Current printer status ( aka monster of Franckenstein printer):

That NOT how user product should like!

Any suggestions is appreciated!
