wii blank screen

Does it still happen after you remove the chip? You may have bridged 2 connections.

 

Sorry, can only think of the obvious. Those points are small - be sure no solder is touching two points.

 

best way to trouble shoot this, is to start at ground zero. and see if it works, if it does work without the chip, you may need to look at the Drive Chip to make sure it is compatible with the wii key. Is this an older wii?

 

try disconnecting the drive. if it still doesn't power on, chances are it's not the mod. if it does power on without drive, then you have a short somewhere.. i.e. spilled solder.

 

Maybe you fried something inside.. it's easily done. What watt iron did you use?

 

Can you still hear audio when you boot the machine?

If so, then your GPU has become disconnected or damaged somehow, sorry if that sounds bad. The first few firmware revisions for the Wii didn't enable the fan for cooling whilst the system was in standby mode, often leading to the machine overheating and damaging itself.

Perhaps your friend haddn't used the machine in quite a while and had left it in standby mode and fried it, which would make sense as to why he believes it was working the last time he had tried it. If you could ask him what version of Wii System Software he was running, that may hold a clue as to whether or not I'm on track with a possible issue.

 

Is this the first time the wii has run on this tv? Maybe it's not compatible with the video mode the wii is outputting.

Remember, the wiikey is only on the dvd-rom... so even if you do bridge points, the wii should still boot - just the drive won't accept / spin discs.

Unless you damaged something when you pulled it apart, I'd suggest trying a different tv.

 

pretty sure the wii itself is defected
