Question No video output anymore?

[ultimasnake]

So long story short, I already asked this in the n00bs forum but since i'm a bit further now in the wii department I'm hoping I don't look like a wii-n00b anymore (i've done some DS-mods, mod-chip installations, solder electronics, fix devices for fun etc).

So a long story short when I tried hooking up a wii to a portable screen I made this horrible wiring mistake (or so I think) and a bit of smoke came out of my wii near or from one of the inductors. Jump scared I quickly removed the wii only to find out I've got no video signal anymore. Further more the last diode just before the pin-header for the wii output is fried.

Smoke came from this area:


BUT! the wii is alive! How do I know that?
1. The power switch turns on
2. The power switch turns green when I press the power button
3. The power switch turns yellow then I press the button shortly after that
4. The wii-mote can connect and re-sync with the wii
5. The wii still produces the horrible menu 'music' after I click A (invisible health screen)!

The music is received when I connect the wii with the external monitor to pin 1 of the pin-header. When I connect the video to pin 3 for composite nothing happens...

I've also tried to attach the video to areas marked as the composite signal on the OMGWTF trim as shown in the image below




But with no luck. Any help would be welcome, it seems that the

Other info:
Board version: CS30 (white wii, 6 layers)
My video output on the back of the board near the chip was on a different spot then on the OMGWTF guide but did manage to find it by tracing it.
No mod-chip
I don't have a TV with composite input so can't test that unfortunately
The monitor works, I can still succesfully hook it up to my pi1 and 2

any help to spark new live into this wii would be awesome!

Remove what you burned and see if you can get video. If you don't have hot air or other desoldering tools, just cover the whole thing in a blob of solder and swipe it off, then clean up the solder as best as you can before turning it on.

Hi Shockslayer, thank you for your reply. First off I managed to find out my board is identical to the one on the layer expansion page (https://bitbuilt.net/forums/index.p...ive-wii-trimming-guide-6-layer-expansion.860/). Second I cleaned up the burned bit and alas no changes. I did notice that the bit of the back of the board does not seem to make any measurable connection between that and the place where the connector is.

I did try to connect the wiring as close to the chip as possible but with no effect.

The smoke came from this area of the board but I'm having a hard time to find out what values I should be able to measure at each point (some of the caps? say 6v but I measure around 1-ish)


Maybe it's just one of those parts that died on me (also) and now the chip is not powered, also in that case I'm guessing that the wii doesn't really do anything special audio wise through the chip except for passthrough (?)

Oh maybe I can measure all voltages on the OMGWTF trim and see what's going on there! But it's almost 0:00 here now and time for bed

If you have a six layer board, I'm not entirely sure that you can grab video from that cap. Grab it here:


If you're getting audio, then your onboard regulators are probably fine.

Yeah I should have updated my screenshot but that's actually where I tried to get it with no success..
