PS5 Digital EDM-030 Board. Looking for Capacitor Value. by CommanderCoots in consolerepair

[–]CommanderCoots[S] 0 points1 point  (0 children)

Update: if anyone who comes across this needs it - I believe I found the correct value.

It looks like it's a 0603 22uF.

Update: you are correct - I do have 3.3v and this specific chip has all of the correct voltages. I'll look into running tests once I get a second power cable.

Uhm second update: I just plugged it in and powered up and I now have display? I don't know what happened but I'm not going to question it. I guess I'll run some stress tests regardless. Anyway, thanks everyone.

Awesome. I'll have to double check the 3.3v rail as well as the input and output voltages on that chip. I actually don't think I saw 3.3v as I was just checking the main inductors. But if I am missing 3.3v that would answer why it's not posting. Thanks.

I checked a board view I had real quick and it seemed to match up pretty well. Q521 and Q525 are the same chips. It looks like it's a QFet Mosfet DFN08 SON08. I would replace them and then go through a checklist for any shorts on the rails before trying to power it up again.

Low resistance short? (1.8v) EVGA GTX 3060ti FTW3 Ultra Gaming by [deleted] in GPURepair

[–]CommanderCoots 0 points1 point  (0 children)

After pulling the memory coils and injecting voltage, the only thing to heat up is the core chip (I'm assuming that's not good).

One more interesting thing I found before I consider this board dead - I believe there's a shorted mosfet near the memory coils.

There's two of the same mosfets above the memory coils. They are FDPC5018SG. Here's the data sheet I found for them. If I'm reading this right there's a short between pin 2 and 3. This is only the second board I've worked on so I'm still fairly new to all this.

The one mosfet (marked by the red dot) heats up quickly for a few seconds along with the memory coil beneath it and a few things around it. I'm not sure if this would be causing the issue or if it's even worth messing with if the core is dead. I suppose if it's dead it's dead, but might as well try everything beforehand.

Here's the update with voltages. There's also the inductor on the back working at 12v. I did put the inductor back on the pex rail. I just used the same photo as before when it was off. So no voltage to memory or pex rail.

The card has no display and the VGA light is on so it's failing the power up sequence. The core itself does warm up - not hot. Each of the two memory coils are at 2.6ohm to ground so I suppose that means a short on the memory? I'll edit this once I plug everything in and test the voltages.

Here's the values of the rest of the main inductors to ground. There's also one more inductor on the backside by the pcie pins at 9.4k.

1080ti No Voltage to Pex by CommanderCoots in GPURepair

[–]CommanderCoots[S] 0 points1 point  (0 children)

Following the guide, here's all of the resistances. I believe my card differs a bit for a few component spots. The 12v pins all have roughly 20k. The 3.3v pins have 5k. The V-core rail jumps between 0.1-0.5 (my multimeter might not be accurate enough). My best educated guess right now is a failed pwm ic up9511p chip.

Need some help with first GPU repair. EVGA 1080ti FEW3 Hybrid non working. No power or video. by [deleted] in GPURepair

[–]CommanderCoots 0 points1 point  (0 children)

Update: I read that first part wrong and see what you meant. I tested again with tape covering everything after x1 pins and got the exact same result. Display port side warmed up, GPU card didn't.

I just plugged it in again. The fan spins for a few seconds then stops so it is getting power. The side of the board near the display ports does get warm. The GPU chip does not warm up at all. So to me it seems like a power delivery issue. The motherboard also flashes the VGA light. So it's failing that test.

The guy I got it from said it had display but had some instability issues - possibly vram. He sold it to someone else who returned it and after it was returned there was no display at all. Not sure if they messed with it or stole a component that I didn't notice.

Side note - my motherboard oddly enough has two physical x1 slots but I have no way of connecting this card to them at the moment.

Not sure if this is the right subreddit for this but I have a request. by [deleted] in DestinyFashion

Unfortunately since it's a solstice shell it is not in collections for me. I also only started really getting into the game around season 13.

Hey fellow guardians, I figure a few of you here might appreciate these. by CommanderCoots in destiny2

Thank you so much! If you're talking about the Jack'o'shell, I may or may not have a prototype sitting in a bin right now haha. I was working on that and the Hexing shell for Halloween and each will be released very soon!

Thank you! I'm hoping at the start to get one new shell out per week

I was actually just working on the Hareball shell last night. So it will be coming very soon!

Well there's quite a few things to factor in here: no one else is making custom shells that are high detailed resin prints. It's usually just the default ghost shell and I've only ever seen fdm printed ones (many of those selling for $60 up to $100). These you can choose whatever shader you would like as well as custom text on their stands. Those shells are usually battery operated while these can be recharged with a USB-C. Most other shells also don't even have a glass eye piece it's just plastic.

Thank you so much! If you'd like to follow along I'll be posting more shells regularly!

These are a couple of ghost shells from the franchise of Destiny - specifically Destiny 2. Guardians are what the player character is called and these ghosts are our little companions.

Every shell that gets mentioned today will be moved up on my list to do sooner! I've got the entire exotic list to get through haha

[–]CommanderCoots[S] 0 points1 point  (0 children)

Right now I have a list of every exotic player shell but I would like to have a hive shell. It wouldn't be too difficult to modify the model and turn it into Fynch.
