Solved Is this a short?

[kjc35]

That circled component blew when I was soldering a wire and I need to know if that could cause a short, as I'm getting that signature green light to red light to off upon turning the system on.

(Ignore the wires, yes they're in the wrong locations but they're not connected to anything)

Thank you!!

That is attached to the green component video line. As for if it shorting could cause that problem, we need an expert.

I've looked everywhere, rewired everything, and it's only happening after that resistor blew. I have another board so perhaps I can just transplant that component?

It's worth a shot.

Don't bother transplanting it, just remove it. Though, if that blew, there's probably a short or something elsewhere...

Yeah you're right. Currently I don't have the connection to turn the Wii on as soon as I turn my main switch on, so I'd have to press the power button on the Wii after. Sometimes the Wii will turn itself on, without pressing that onboard button, so that may be a clue to where the short is? And that's with the blown component off.

Pics of the whole board? Also, I've had some wii's that were unmodified that would randomly turn on by themselves when you apply power, it's just a weird quirk of the MX chip.

I've heard about that, however this board hasn't automatically turned on until now, and I've been using the same set up for months. Here are some pics, lemme know if there's a specific spot you'd like to see. The wiring looks a lot uglier than it has been but this short has me trying every wire.

On the bottom left of the last picture, it looks like you may need to sand that edge, there could be shorts there.

Alright, it's definitely an ugly cut so I'll try that later today. Thanks!

EDIT: so it looks like, if that edge is sanded correctly, there's a short elsewhere. Still hits me with the on-off.

Were you running the board without heatsinks as shown in the picture?

 

[kjc35]

Not when I tried, would it overheat that fast??

 

[cheese]

It takes a minute or two, but if you leave it while you do something else, it is easy to accidentally overheat and potentially damage the cpu/gpu.

Try removing the wifi/bluetooth modules, and having nothing plugged into any of the ports. Also, what's under the duct tape at the top left of the board?

 

[kjc35]

I only had the heat sink off for a moment, just long enough to see if it'd turn on, so the CPU should be fine. Under the duct tape is the clock battery but the positive wire isn't connected. I'll unplug everything but power when I get home from school and see.

If the board boots, you should get a black screen (unless you installed nowifi ioses).

Welp, now it looks like the board won't even turn on in the first place, the red light won't come on and there's nothing connected but 15V power. Guess I'll just get a new board and restart

The red light not working doesn't necessarily mean it's broken. Sometimes the red light stops working while the Wii itself still works, though I'm not sure why.

It looks pretty dead, none of the main voltage lines are showing anything and the CPU is cold. Thank you though, to everyone who tried to help!!

EDIT: would custom regulators be able to save the board? I just remembered that I had some all setup but I was waiting to use them for a handheld... if there's a chance I'll go ahead and use them here!

It's possible, but it would be a good idea to trim the board if you are going to use custom regs, since it will cut off any potential shorts you may have elsewhere on the board, and you won't have to manually remove the onboard regulators. Did you install PM with nowifi? If not, your best bet would be to get a new board...

I totally forgot that PM was needed for the OMGWTF trim, so new board here I come... thanks again guys!
