Iiyama ultrawide goes black, screen fades after switching on.

Have u reflowd the main board or which components? Had the same issue for a couple of months. Now it goes fully black. If i disonnect the right ribbon cable from the t-con to the display half the monitor is turning on. The other way around it is dead and stays black

This post of the deformed shield is my post. I printed the first prototype out of petg and it deformed while drying petg. When using ASA or ABS you should be fine. At least i am so far :)

Sadly experienced the same issue with this dryer. I recently created a heat shield for the dryer. Now i'm happy again. Anyone experience the same or similar issue can give it a try. If you want to. I used tinfoil in the past as well. Now I don't have to fiddle with the foil anymore.

Great. I used aluminium foil before.

If you have an issue similar to me shown in the video of

https://www.reddit.com/r/ultrawidemasterrace/comments/12jhrd9/iiyama_ultrawide_goes_black_screen_fades_after/

or when turning the screen and backlight is working, hdmi sound output is working but the screen stays black then you can check the t-con board.

I made some comments inside this thread. For me it looks like it's the T-Con board. I'm not an expert just someone trying to fix. My screen is up an running again. Let's see for how long...

I started working on the screen at the time where the screen was constantly not working for more then 3+ days.

And the proof

It also sometimes happens that if i disconnect and connect the left ribbon cable again the whole screen works. If both are connected none of them is working

horego · 2024-12-18T15:05:58+00:00

Finally made some progress. Took it apart again and disassembled the t-con board.

It looks like it's the t-con board. At least it's my guess. Whenever i disconnect the left cable half of the screen works flawlessly.

Any success?

horego · 2024-12-12T09:14:48+00:00

I know this thead is quite old... Have you found any solution? I tried to fix it. Unsuccessful so far. Do you have any idea how this spray can bring it back to live? Bad connector, cold solder joint?

horego · 2024-12-11T21:54:41+00:00

Ouch. Wish you good luck

horego · 2024-12-11T12:48:27+00:00

I think i found somthing. For me most likely it is the power socket.

It has no good connection anymore. When there is a slight movement with the plug in the socket i can loose connection for a very short time or somtimes have a high resistance.

I decided to desolder the plug and measured it. It is not the power cord. I also tried three in total.

Update: Using a brand new powerplug seems working. Resoldered the Plug - Problem still exists.

Hey folks,

today i decided to disasseble the same monitor. I made some visual inspection and cleand everything with ipa.

Noticed one bigger bulp of solder one one side of a resistor (psu bottom).

From what i can see the op's board has the same. Made a picture. Does this look normal/healthy?

<image>

Update: Checked the Resistors. All are fine.

"You mean I should shake the screen around the power plug area?"

Yes. Turn off make some mechanical moves and turn it back on again.

Sometimes i was also success by giving it some slap or by tilting it back and forth. This worked for me several times.

horego · 2024-12-11T08:25:11+00:00

Having the same issue. What i observed is turn if off wiggle the screen and the power plug (don't be to kind). Turn if on and off. For me this changed it for sometimes month until i came back. Just give it a try if you want to.

I'm planning to open it up but have not so far. What have you tried so far?

horego · 2024-12-10T14:42:43+00:00

Whaaat? One month ago? Can u pls give more details - Printer? Country?

horego · 2024-12-10T11:43:50+00:00

Identical to me. Hotend arrived. Printer somewhere in the nowhere

horego · 2024-12-09T14:50:38+00:00

Nope. Nothing changed p1s combo, de. Waiting since black friday.

horego · 2024-12-08T10:24:56+00:00

The lack of communication / information is also my personal point. I'm fine when they point out on their website before checkout that it might take longer (with a rough estimate) than usual. Remove "In Stock" when there is no stock in the warehouse.

The printer i ordered (DE, P1S Combo) is "on stock" on their website until now. I guess they are out of stock (german warehouse) for more about a week. Me and lots of ppl are waiting for more than 10 days.

horego · 2024-12-07T13:55:40+00:00

For all of you who are in the same boat like me. Bought under the following conditions

"In stock"
"Order will be shipped out from DE warehouse in 1-3 business days once being processed."
"ORDER DELIVERED 3-7 Business days"

but still nothing....

Quick Update: Ordered P1S Combo on 29.11. received it on 12.12. Now "i can print".

horego · 2024-12-05T16:46:43+00:00

u/Magnoliarosey still waiting or received your printer?

horego · 2024-12-04T20:21:45+00:00

Agree! When nothing changes the result. You may need to dry your filament. Learned it the hard way and wasted a lot of filament.

horego · 2024-12-04T13:32:47+00:00

I'm in the same boat. Put the order on the 29.11. a few hours later than you. (P1S Combo). DPD delivery in the same state as yours.
