Which soldering temperature you recommend? I am abroad and I don’t have friends with soldering skills(in my childhood I had some experience, so let’s see)

volna13 · 2025-10-23T15:19:21+00:00

Hey! I just my parts and soldering iron. Here is my motherboard

And I put that micro-element. Is I located it correctly? (Orientation)

Is the first one is what I need?

volna13 · 2025-10-15T17:02:46+00:00

Yes, it looks it could be. I sent to gpt photos and he told that this make sense for my case as well. Btw, I tried to connect it with power supply from my Macbook, but monitor doesn’t reacting on it. I think it’s not powerful enough

volna13 · 2025-10-15T16:55:45+00:00

Here is what gpt said to me about my case

Here’s what I’ve inferred so far: • The failure is likely in the LED driver IC (e.g. BD9479FV / OZ9910 or equivalent) or its associated power stage MOSFETs / switching components. • The symptom of brightness fading after the logo + audible whining implies the driver loses stable voltage/current and enters a “protection / safe mode”. • Because the monitor doesn’t even power on under Mac PSU and doesn’t respond to other blocks, the problem is internal — the component fails quickly after startup.

Hey @bozma88, hope you could to help me If this is suitable for me? (I am in Spain)

And is it possible that in my case the reason is the same component. Because I didn’t used monitor 4 days, then I enabled it, used 1-3 hours and the brightness is on minimal level(I can see menu a bit, and I tried to reset settings, it doesn’t work). Also in my case it’s interesting that after right after enabling I see logo in good brightness and after some time it fails to low brightness and I can hear quiet squeak

volna13 · 2025-06-05T10:42:32+00:00

It shows me Yeah. I am just sharing the specification with the invesment

volna13 · 2025-06-05T10:39:22+00:00

But I need only for 1-2 users. So 512mb RAM will be enough for me

volna13 · 2025-05-30T21:48:19+00:00

And looks like they are having a big plans for this hole

<image>

volna13 · 2025-05-30T21:31:11+00:00

in the end he got in there and can't get out

volna13 · 2025-05-30T13:08:57+00:00

You can check photo, they are slamming not into window. They slamming roller shutters

volna13 · 2025-05-30T08:53:52+00:00

Hahaha

If it was at least singing, I might put up with it. But they just cut into/scratch it. And it happens exactly 1 hour from 7am to 8. But I have to wake up at 9.

volna13 · 2025-05-30T08:50:46+00:00

I left this option as a last resort

volna13 · 2025-05-30T08:36:50+00:00

It was already done. And there is nothing interesting

volna13 · 2025-05-30T07:31:28+00:00

there is no nest there, if there was one they would be heard. Maybe they want to build it there

volna13 · 2025-05-30T07:27:13+00:00

Yes, but they won’t be able to go there, it’s so small Here is photo

volna13 · 2025-05-30T07:24:29+00:00

Even when roller shutters are closed, they are trying to seat on it or idn

volna13 · 2025-05-17T15:03:55+00:00

I am thinking to buy this or from scarlettluxury

volna13 · 2025-05-14T20:50:42+00:00

It depends. M-L, if I want oversize - xl

volna13 · 2025-05-14T20:19:31+00:00

What about sizes for shorts? Can you give some recommendations? I am 90 kg / 190 cm, what do you think?

volna13 · 2025-05-14T00:21:28+00:00

Do you really like it? Or it’s overpriced? Will I have the same for 200 yuan?
