Jana, It sounds like the WIFI/bluetooth module is bad in the gamepad. They are available online and are relatively easy to install. There is a nice tutorial here on iFixit. Hope this helps, JK Wii U GamePad Bluetooth Replacement
Nate, Sounds like the battery is dead. If you’re able to play the controller with it plugged in, and the indicator shows it’s charging, I would put my money on a bad battery. I had the same issue with another controller. JK
Hi Floyd, Seems like you’ve tried everything I would suggest, but not to insult you, I am assuming that you made sure that the TV selector was set to the proper inputs? (HDMI TO HDMI, AV TO AV,…..) I have done the same thing, only to realize I hadn’t selected the correct input. I have repaired several Wii U consoles with this same issue, a couple were the HDMI chip, (available online) and several HDMI ports, but sad to say, nothing like what you are describing. Most always you can get the AV cables to work. One more question, when you connect the console using the HDMI cable, does it have sound? Thanks. J.K
We_Have_Fun_Here, I would start by looking into the card slot, checking for bent or missing pins. This is a common issue and will cause the issue as you related. There are 3DS readers available for replacement if you are handy with a soldering iron. If not, you could find a local repair shop that can change it for you. Hope this helps.
wm.jones, This may sound odd but, are you sure the screen is for an iPhone 6? If it’s not, it will never fit. Or is it that you having difficulty trying to get the connectors to attach to the board? If that is the case, you may have bent pins in the connector. They are easily damaged if they are not lined up correctly, and pressure is applied to try and attach them. This is a common issue. If so, then you’ll need to find someone that can install a new one for you.
Did you check the battery? Most often, after years of little or no use, it will lose its ability to hold a charge. So, I would start there. If you have a way to check the charge on the battery, that will help to see if it is dead. Although batteries are relatively inexpensive and easy to find, so if you don’t have any testing equipment, just try a new battery. If that is not the issue, there are fuses that are related to the charging system that are put in place to stop a power surge from destroying your gamepad. It could be that one of them is blown. They are extremely small and it would require someone that can micro-solder to replace it. I wouldn’t recommend putting a solder blob in its place, although that may sound like an easy solution, it will not protect the circuit, which is why they are there to begin with. Look for the F1 and F2 fuses on the motherboard, but be careful not to poke around them too much, like I said, they are very tiny and easy to knock off the board. If one or both are bad, have...
I agree with Mark’s good advice. You could also just check to make sure that the connector end of the flex is not smudged by oil residue from your fingers. This can also be enough to keep it from making contact. Clean the contact with alcohol and then try it again. If that doesn’t do it, you can always replace the home button assembly and flex. I’m sure you can find the parts here on iFixit.
Check the HDMI port. If the pins are broken or missing, or the port itself is loose in the housing, you will need to replace it. Note: Replacing the HDMI port will require special tools and skill. You could damage the MB if you are not careful. Have fun!.
If you replace the screen, make sure to transfer the plastic ear piece from the original screen to the replacement. (It’s the one with the metal bar) I was unable to find a replacement through any of the suppliers I use.
Just a heads up:
