What do you mean that you tried 3 units... what is the serial number of the wii
when you modded it did you backup the nand and did you install priiloader!!
Got a wii black here, with the follow problems:
When power up the wii, normaly you hear the drive make a short sound (Startup sound)
This wii, when i power it up you hear NO sound, try 3 different units, no different.
Olso the screen stay black, change bluetooth modules, olso change wifi module.
screen stay on black and the drive not make the startup sound.
Can not get into recovery menu.
anybody can say what the problem can be?
check the flat cable which connecting the dvd-rom and the motherboard.
It's just a guess but I'm betting that you have a no signal screen and not a black screen. There is a difference. Do you see no signal or something similar on your TV? If your TV doesn't display that when there isn't a signal received by default then watch the screen as you boot. If if flickers or gets a little brighter then you have a black screen. If it does nothing then you have a no signal screen.
Although billyhome is giving good advice, a bad cable doesn't explain why your Wii wont boot. You may have a major hardware failure causing both problems. I don't think that there is any software involved when it comes to making the drive spin up on boot. If it's not, that points to some other non-software problem.
What does the power l.e.d. do when you power on? Does it go from red to green or does it go from red to completely off? If it goes to green then tell us if the drive light flashes quickly or stays solid when powering on the console.
I would normally guess a bad drive or bad drive pwr cable but you said you swapped out both right? The only thing I can suggest is to check and make sure the pwr cable is connected to the motherboard correctly. Check inside the connector and make sure the pins aren't bent or anything. If the drive is in working condition then the main board isn't supplying power to it for some reason. Try troubleshooting the voltage with a multi-meter by seeing where it cuts out. First check the end of the power cable that connects to the drive and go from there.
If voltage is good then you need to recheck the Data/Ribbon cable. If the ribbon cable isn't connected correctly, you will have the same issue.
