I'm seeking more ideas of what to try with this stubborn no-signal issue.

BACKGROUND:

I have an original, well cared for 2006 Wii that's long been out of commission with the common no-signal problem. When turned on, the green power light illuminates and the disc player makes its usual start up noises. Bluetooth sync is dead. I have 2 original controllers that go into sync mode but the Wii never syncs to them. The controller's LEDs simply flash until they time out. No video signal and no bluetooth sync is a strong indicator of a faulty bluetooth board according to many posts across the web. Model no. is RVL-001(USA) and 01 first revision motherboard.

THINGS TRIED:

  • Replaced the Bluetooth board (with what I was told was a tested authentic board from an eBay vendor).
  • Cleaned all of the contacts for bluetooth and WiFi boards and firmly reseated both. Also tried cleaning and reseating the original bluetooth board.
  • Cleaned power / video ports (motherboard and all else inside is totally clean to begin with and no corrosion or loose parts found).
  • Power supply is providing a solid 12v.
  • Tested with 2 authentic Wii video cables (composite & component) seem fine with resistance tested successfully on both.
  • Tried to unplug power for 2 minutes and then plug directly into outlet with nothing connected to Wii as reset without success.
  • Tried holding down Reset button and then power on without success.
  • I've seen mention of WiFi connection reset, but I can't get to any menus to try that. I don't think the Wii boots at all. It seems to be stopping immediately in its boot sequence with likely the busted bluetooth sync issue. The unit is within direct 12ft of fast mesh network node so there's no problem there.
  • It's never been home-brewed and is completely stock. I don't know what version its firmware is at since I can't get to any menus to see that.
  • Curiously, after the green light shows when power button is pressed, I can hold down the power button to turn off after a few seconds and light turns red as normal.

THINGS NOT TRIED:

  • I can't find online an authentic Wii WiFi board to replace the current one. Regardless, I assume the immediately dead bluetooth sync problem wouldn't be fixed by a new WiFi board. There are tons of Wii U WiFi boards out there but can't find one for original Wii.
  • I don't have a Gamecube controller to try anything with.
  • Haven't tried testing the power under load off the motherboard as I don't really know what and where to test that.
  • Unfortunately, I don't even have a game currently to test with. Thought I had a bunch in storage but no. Have to borrow one.

HELP

Any further ideas or procedures are much appreciated!

A good place to start would be where to test voltage on the motherboard when turned on. I haven't been able to find any info or videos on that kind of demo.

Hi,
  Looks like you've tried almost everything except a few things. For one, the Wii Wireless Wifi board & Antenna. I'm not sure but I think that the bluetooth will not work without the Wii Wireless Wifi board & Antenna. Try replacing that. I do believe I've seen it for around $7 to $9 dollars.

Thanks for replying, Jade. I did finally find a WiFi chip on eBay that matches mine and doesn't cost >$125. Gotta wait for delivery from China so likely more than a month unfortunately.

As I mentioned in THINGS NOT TRIED section before, I have my doubts WiFi is the problem because both Wiimotes never sync which would suggest it's the BT chip that's dead. Still, who knows, maybe a busted WiFi chip somehow stops the Bluetooth board from being accessible.

I bought a second BT chip replacement as a backup too. I'll report back on any success or failures when they arrive.

Would I be out of line to ask how much you paid for it? It's OK if you don't want to say.

Was under $10 shipped and arrived in CA inside of a week from https://www.ebay.com/str/gkhtsales?_trksid=p2047675.m3561.l2563.

Unfortunately, installing the WiFi chip didn't fix the problem. I ordered another Bluetooth chip because that still seems like the problem if it won't sync to controllers.

Also ordered WD-40 Specialist Contact Cleaner Spray to give the board a thorough cleaning (even though it's about the cleanest console or computer I've ever disassembled; was hardly a speck of dust anywhere--even on the fan!). Once the new BT chip arrives, I'll tear it down and really clean / inspect it and report back.

BitBuilt Forum also has what looks like a comprehensive illustrated guide to which chips draw what power and on which terminals: https://bitbuilt.net/forums/index.php?threads/the-definitive-wii-trimming-guide.198/

When I get the next BT chip and cleaner spray, I'll try measuring voltage off the main board and see if it matches. If not, then a new power supply might help because maybe it's not providing enough power under load (mine does measure 12v when not attached to the console). Otherwise, that could mean a chip soldered to the board is failing.

I'm obsessed now! I WILL find a way to fix this stubborn lit'l thing!  :hammer_head:

So, the prognosis is grim and I'm out of options to try. Latest steps include:

  • ANOTHER BLUETOOTH CHIP: Received and installed a second used (but allegedly tested working) Bluetooth chip. No success.
  • CLEANING: Thoroughly cleaned mother and all daughter boards with WD-40 Specialist Contact Cleaner Spray. No help.
  • POWER SUPPLY TEST: Carefully measured voltage on the dozens of connectors for the many chips on the motherboard (it mostly checked out, a couple that likely should have been 3.3v were measuring 2v; problem is the voltage diagrams from https://bitbuilt.net/forums/index.php?threads/the-definitive-wii-trimming-guide.198/ is for a later board and the layout didn't match mine perfectly so it was a search to find connections that were closest to the images). My takeaway here is that the power supply is delivering full power to the board and not failing to provide voltage under load.
  • REAL WORLD POWER TEST: Found another working Wii console and tried testing its power supply on my Wii, but no change. Then I plugged the other working console into my power supply and it ran fine so it's not my power and IS my console that has the problem.
[Insert defeated sad face here] Seems like something major is jacked on the motherboard which is impossible for me to find and fix with my electronic repair experience.

I found some used motherboards on eBay for $30-$50. If I can get one for $30 or less, it's worth it. Otherwise, working consoles are running $65-$85 on eBay.
