Black Screen on T-Embed (Please help)

[undone drift]

Re-flash from bruce flasher

[eager drum]

Ive already tried, i reflashed beta and the latest release and yet its still doing the same thing.

[undone drift]

Try a diffrent sd card and remove the modules

Then flash base bruce not beta

[eager drum]

Alr

[undone drift]

If this works then install beta

[eager drum]

Ok, thanks for your help.

[eager drum]

Its still doing the same thing, i took the case off and unplugged the modules, used a completely different SD card and its still displaying nothing, if there are any other recommendations please tell me.

[undone drift]

Try unplugging battery from mainboard

And reseating it

[eager drum]

Yea i did unplug it, im only using a cord for its power.

[undone drift]

Dang

Uhh

[eager drum]

Idk even know how it happened, i was trying one of the features on beta and it froze then turned off, and its been the same since then.

[undone drift]

Is there any attatchment ports like on the m5stick

[eager drum]

Wdym

[eager drum]

Oh, no there isnt.

[undone drift]

Dang

My stickc fixed itshelf by putting a fuse on the 5v and letting it burn

Had the same problem

I don't recommend this tho

[eager drum]

Well, im going to try and factory reset it and burn its original firmware to see if this changes anything, if not ill most likely have to resort to buying a new one unfortunately.

[undone drift]

Dang alr

Did you solder anything in there ? Just unplug everything and pull off the case so you only got the screen unplug the screen and put it back on then go with a toothbrush though the main board and rebuilt everything then try flashing a different firmware like capibara zero if it doesn’t work when you flash it you can select flash or view logs go on view logs and reset device then flash Bruce back on hope it helps

How do i unplug the screen?

[tardy lark]

@eager drum before asking, did you read the Wiki? https://github.com/pr3y/Bruce/wiki

[trim ether]

1. Power Off: Make sure the device is turned off and unplugged.
   2. Remove Back Screws: Unscrew the screws on the back of the T-Embed.
   3. Open Shell: Carefully separate the shell using a plastic pry tool to avoid damage.
   4. Access the PCB: Once opened, locate the screen ribbon cable.
   5. Disconnect Screen:
   • Gently lift the latch on the ribbon connector (ZIF type).
   • Slide the ribbon cable out to disconnect the screen.
   6. Remove Screen (Optional): If you need to fully remove the screen:
   • Unscrew or unclip it from the PCB depending on the model.

Okay, i will try this in a minute, but if this does not work can i just buy the same display and replace the screen completely? Because i believe that is the problem.

[trim ether]

Idk I don’t think so mine screen was just like that but it was because I tried soldering the nrf24 but it bridged on esp32 my friend cleanedit and it worked again

I don’t think you can buy the same screen but you can scroll a bit on aliexpress maby you find something similar

[eager drum]

Well thanks for your help, i ended up looking further into my T-embed and i did clean it, i inspected the display and there was nothing i could do to fix it, after i tried what you recommended i put it back together and still the same thing. But it's alright, i'll just have to buy a new one.

[eager drum]

Oh and also, originally i was also going to solder a nrf board to my t embed before the screen thing happened, but when i do get a nee one i’d like to know if this wiring diagram is fine and will work, im asking because ive seen three different wiring diagrams.

[glossy dock]

use this wiring diagram

i use this with ebyte e01 work perfect

for black display try hard reset esp32 https://www.youtube.com/watch?v=3oEvXhgHZHo&t=198s

Man if you dont really got at soldering I defenedly dont think you Shoud try it on the new one I already made some projects with soldering and I still failed so its just Not Worth if You aint realy good at it it would Probely be better to buy a external sd sniffer where no soldering is needed

And I defently wouldnt buy a new one before you Tested everything did you reset youre device when no battery is in

?

Did You Flash different firmware

Did You Took it off Like this and cleanded the golden Ports with a thoothbrush

I have the same problem

[solemn apex]

When I first bought it, I had the same problem during the first week. I tried everything — reflashing, removing and reattaching the screen, even contacting LilyGO — but nothing worked. Eventually, I gave up and put it back in the box.

Fast forward a month later, yesterday around 4 AM, I decided to check it again. When I powered it on, it was working! But after some time, the screen went black again (by black, I mean the screen was lit, but there was no image or data showing).

I removed the battery, reflashed it, and now it’s working fine again. Based on my experience and understanding, I think the issue has something to do with the motherboard, battery, or power supply.

[subtle sleet]

Yes, it happens to me too, but I would like a definitive solution.

[crimson sentinel]

i tried a 32gb sd card with mine and it kept crashing, moved to a 16gb and its fine

[warped mantle]

i dont recommend t embeds i still have mine and it does the same thing it just sits in a bag because there isnt a fix

atleast not that anyones found

[kindred blaze]

Take battery out and in

[subtle sleet]

I replaced the screen but it doesn't work
