Question Help me please

[PeytonJP]

I feel like I hooked everything up good enough to start up my wii. Can anyone tell me what I'm doing wrong please? I'll attach some pics below. Any help at all will be greatly appreciated

Aside from all the burnt flux on the board that needs cleaning, you have a PMS-2 so you can remove the 1.8v wire to resolve that conflict. Gluing exposed wires to the battery terminals is also a mistake. You need to get a 18650 cell cradle with spring contacts, trying to glue wires to the battery will never give you good enough contact to run the system.

OK. I believe I got everything that was said. First, is the burnt flux your talking about the blackish stuff by the LDO? if so, how do I clean it? as for the 1.8 v wire do I remove it completely? Or do I do something else with it. Above all, I really appreciate you taking the time out of your day to help. This website has been the best, and its really tought me a whole lot. thanks!

Hi !
First yes, you have to disconnect the 1.8V wire.
If you keep the LDO, you mustn’t have 1.8V wire but if you remove the LDO, you must have a 1.8V wire.

Then for the flux, you can easily clean it with isopropyl alcohol (IPA) or with flux cleaner.
You should clean every solder to avoid any problem.

Have a great day !

To clean flux you use isopropyl alcohol, the highest concentration you can find + tissues and a soft bristled toothbrush. I use a gallon jug of 99% that I got from an art store, but most hardware stores and cleaning supply stores will carry it too. Apply some via a small spray bottle, or a saturated tissue, let it sit for a moment, give it a light scrub with the brush, apply some more, then wipe up all you can with a tissue. Repeat until clean.

And yeah you can remove the 1.8v wire entirely. The PMS-2 has an onboard 1.8v regulator, unlike the PMS-Lite which does not. With the LDO still on the Wii, the two 1.8v feeds are conflicting with each other, which can cause (among many other problems) inability to boot. You can remove the LDO and replace it with the PMS-2's 1.8v output later if you like, but for now it's easier to leave the LDO.

Hey thanks! I'll keep everyone updated with progress as I go. I removed the 1.8 completely, and am about to start cleaning up as well. Odd thing here, but heres my situation. At this point the u10 has already been relocated and everything, but then I realized that my pms didn't need that. So... I took the wire and stuck it on my pms. Leaving it the way it is, will it be ok? Thanks

Awesome. To everyone who has helped me today, THANK YOU! I think I've been set in the right direction. When I try to measure the correct voltage lines, for example if I want to see if my 3.3 v line is good, how do I do that? Because I've been setting my multimeter to 20 volts and then putting the ground to the battery and then my positive to the wire. I know, I'm not good at this stuff just yet, but I'm winging it lol. Anyways, thanks again, and have a good night!

Yeah that's fine. As long as the via is connected to either the U10 chip or the U10 pad on the PMS, you're good. The U10 chip can just be left on the Wii unused, it won't do anything funky.

Setting your multimeter to DC 20v is the correct range. It shouldn't make a difference, but try putting the negative probe on a GND wire point rather than the negative terminal of the battery. When the PMS is turned on you should get a reading. If you aren't getting proper readings, the troubleshooting procedure is to disconnect the PMS from the Wii and check the voltage outputs again. If they are correct with the Wii disconnected, then there is likely a fault on the Wii itself that will need to be identified.

 

[PeytonJP]

Makes sense. I'll do that and then repost what I find on here. It will likely be a while later as I'm at college right now. Thank you!

 

[PeytonJP]

OK. I got things figured out. Turns out I wired my on button wrong out of all things. I'm getting good voltages everywhere except my 5. my multimeter reads 5.1 volts. Actually, when I turned it on my pms when it was all wired up to everything, the screens circuit board started making a high pitched noise. I unplugged my battery and am checking here on what I do now. Any ideas?

A margin of about 10% either side of the desired voltage is considered to be okay, so 5.1v is acceptable. The high pitched noise is most likely either coil whine, or a busted capacitor. Can you localise approximately where on the PCB the sound is coming from?

It's a little hard to tell. But I think it's one of the ones that I circled in the picture.

 

[PeytonJP]

Good news! The wii boots... but the screen is still having problems. I just wired the wii to some video cables and plugged it into the tv, and it works

 

[Stitches]

Grats on the working trim!

There's a lot of conductive debris on the screen board, and C142 appears to be shorted to the nearby 8 leg IC by a solder blob. A cleaning wouldn't go amiss

 

[PeytonJP]

Got it. I'll get that done and then update you again. Thank you!
