Thanks, I'm going to put in a 0ohm resistor. Kinda stupid that shorting a device meant to be shorted would damage it.... -
Thanks but I wanna try to do this myself....Leave a comment:

I think it's a 0hm resistor. Short it with a screwdriver and it works normal. `Makes sense since not many resistors have that many zeros. I wonder if I should replace it with another zero ohm resistor just put in a fuse? I might try 100, 200, 300, and etc to see if there's a different reaction from the device. It's funny because nothing in here makes use of the heatsink looking giant metal casing.

I killed my VC04 Pro and need help
Was trying to find a short on my motherboard and it started to smell. I left it alone and now the display always shows 4.095 like there's a constant short. Took it apart and something that was toast to the point that I don't know what it was. I assume resistor since it says R28 next to it. Anyone know what this resistor value is suppose to be? Has anyone else ran into this issue with this tool? Still says 4.095 even though I removed the resistor.

Didn't find the cause of the short but I found this. I thought for certain this might have been the cause of the short because one of the 3VSB lines runs to this but the two that look shorted aren't the 3VSB. I thought that this might have just shorted out the entire component and thus taking the 3VSB down with it, but nope. Took a lot of force with an exacto knife to get that chunk of metal out. I then removed it and nothing on it is shorted plus the 3VSB short still exists. I wonder if that's was like that from factory or did my cousin who used to own this board drop some liquid metal and then...

Creative SB1350 identify component
Front headphone connection stopped working on this soundcard of mine and I started checking for shorts and found some that go to this thing. I tried to Google it but nothing. Anyone know what this component is?

Thank you, this is a big help. I'm using OpenBoardView since I use Linux Mint and it seems to work. All the shorts I've found seem to be connected and it's called 3VSB. Both GS7133 IC's are connected to each other but one is VIN and other is VOUT. Doesn't look like this goes to the B550 chip itself, so that's good. I do have a tool to inject voltage but the tool itself starts to smell like burning electronics. I really wish thermal cameras weren't expensive. Maybe I can visually look where each of the 3VSB lines end up and hope I can see visible damage?...Leave a comment:

I tried searching MS-7C91 and just this thread came up. LDO chip, you mean the GS7133? Those weren't bad. I was looking at the connector to see which if any is going to ground and +3.3V, a couple of +5V, PG, -5V, and +12 are going to ground. Plus there's a whole bunch of capacitors and stuff around the B550 chip itself that are shorted, so I'm thinking the B550 chip is bad. I've tried injecting in 1.8V and 3V on like the VIN and VOUT lines and I can't find anything getting hot. I don't know 100%, but if the B550 is gone then there's no point trying to fix this board....Leave a comment:

Ok I'm an idiot. Took me a year to see this. The product number was staring at me in my face. It's a MS-7C91 VER:3.0 . I was looking at the GS7133 IC near the PCIE because it has a short to ground for VOUT and then I see this. The GS7133 up top of the motherboard has a short to VIN. Can you find the schematic for me?

Hey it's me again, been a year. Gonna try another attempt to fix this, and by fix I mean I still need a diagram for boardviewer. If anyone knows where I can find one, please share?

Re: MSI MAG B550 Torpedo help
Sorry it's been a while. I can't see anything like this on the board. Maybe 13C91-3.0? Underneath has P&Q 2044 CM4 94V-0 E162264....Leave a comment:

Re: MSI MAG B550 Torpedo help
I tried injection voltage to the VIN pin that was for the "GS7133" and nothing. No smoke, no heat, no nothing. I started to look for another "GS7133" and I did and that one also has a shorted VIN pin. I started looking around the board with my meter looking for shorts and I found a few SMD capacitors that were shorted, except that they weren't when I removed them. The short is someplace else. I'm thinking that the two "GS7133's" on the board have VIN's going to the same source that could be shorted. Can't be both just so...Leave a comment:

Re: MSI MAG B550 Torpedo help
If 40 ohms isn't ok then 20 ohms is worse. I guess I can just inject voltage and see what hurts to touch?...Leave a comment:

Re: MSI MAG B550 Torpedo help
I watch NorthRidgeFix religiously. Does anyone have a diagram for this motherboard? I took out the GS7133 successfully painful and also found a capacitor shorting to ground that I removed. The capacitor was going to "VIN" and from the GS7133 spec sheet it shows that it has a 10uf capacitor before going to ground. I also have a short on "VOUT" and that also has a 10uf capacitor before ground according to the spec sheet. I don't know where that capacitor is.
I don't have a thermal camera because they're expensive,...Leave a comment:

Re: MSI MAG B550 Torpedo help
Found the data sheet and the stupid thing has a pad underneath for ground. I also ordered 10 for $10 off Ebay which may take a couple of weeks. My plan is to use the Dremel to grid it down enough to reach that ground pad and then use my soldering iron to remove it.

MSI MAG B550 Torpedo help
My cousin gave me a free broken motherboard that would be an upgrade over my MSI B350 Tomahawk and I'm trying to fix it and I found the problem by burning my finger. It sits between the PCIE slots and reads "GS7133" and "RK1G9AKWA". Google shows me nothing about this or where to get a new one. As you can see I tried to get it out but my cheap Ebay hot air and solder iron just doesn't get it hot enough. I tried mixing the solder with my leaded solder it still won't come off. I'm afraid to use more hot air so I was thinking of using a dremel to grind the chip away and then using... -
Re: BIOS Lenovo IdeaPad 3 15ARE05 (NM-C861)
Can't find the original chip for my original motherboard but I did solder the other motherboards chip onto the CH341a and both bin's are still reporting different md5sum. Even though I've only used this for turning a fake GTX 960 into a what it was originally unsuccessfully, maybe the CH341a is bad? What's the chances that both boards have bad bios chips? I'm just gonna order another one and see if the results are different.Leave a comment:

Re: BIOS Lenovo IdeaPad 3 15ARE05 (NM-C861)
Wait, you can solder it straight to the CH341a board? I'm gonna try this later. Soon as I find the chip for my original board because I think I lost it....Leave a comment:

Re: BIOS Lenovo IdeaPad 3 15ARE05 (NM-C861)
I did this and NeoProgrammer couldn't verify the flash. So I got this motherboard off Ebay that's not the same board but does fit and does turn on... sometimes. At some point this board will not turn back on and will need me to unplug the battery and cmos battery, but sometimes I get lucky and it turns on. The motherboard with the 3500U was meant for a IdeaPad 3 14ADA05, while my original board has a 4500U. I decided to take the flash chip off which was reported to be a W25Q64.W which is half the size of my original board. Tried...Leave a comment:
