Hello everyone,

First time posting here and I've been repairing Wiis quite recently. However, there's one issue that's been bugging me.

On this one Wii, I can sync a Wii remote successfully and the menu pops up but for less than a second before the screen goes black and flips between No Signal and just a black screen with the words "Component" in the top right.

On occasion, after a minute, the menu screen and music would appear for a split second before going black.

Any suggestions?

Does it only happen with that specific wii?
Yes, I've tested other Wiis with the same cables. Those work. I even tried resoldering one of the AV port nubs on the back of this faulty Wii's motherboard. For a split second that the menu was on, I could only see the Mii channel and the Amazon channel

Is it stable on the health and safety screen or priiloader (if installed)?

Does it happen with composite/rgb/svideo?

I can't see the health and safety screen not Priiloader. I only have composite cables to test this out, as well as an HDMI adapter. Nether works

Turn off Wii. Unplug the composite cable on the Wii end. Wait about 30 seconds. Plug the composite cable back into the Wii.

Don't have an older TV. I could always buy a replacement motherboard off of eBay but there also might be some virtual games on the hard drive itself. Wherever that unit is on the motherboard.

The NAND is encrypted, you’d need to hack it to extract the key even if you dump it.

Is your HDMI adapter a Wii2HDMI?

Out of curiosity have you inspected the board? Especially around the video encoder and the associated traces?

Still not working. Also, I noticed that the video output names seems to be switching between Not Support! Then 480p SD. I might have seen something like 575p SD. I don't know

This issue sounds similar to my primary Wii unit (RVL-001-01).

When the unit was booted from the very start, only black screen is present in component mode. I had to wait for 3-8 minutes for the image/audio to come on the TV.

When I tested this on my older TVs, it has some trippy image warping effect which isn't present in my newer TVs. The more I wait, the more the warping image fade away and display properly.
