故障の確認の仕方や、交換が必要なパーツ、道具などを教えていただけると嬉しいです。

よろしくお願いします。

（ちなみに、十字キーは上下と左は効きます 😫）

音は出るが画面が付かなかったため（充電ケーブルを繋ぐと電源は入る）、原因を探るために分解しました。

（この時点ではボタンの効きはちゃんと確認していませんでした。）

使用したガイドはNintendo Switch Lite Screen Replacementですが、スクリーンのテープを外す道具を持っていなかっためその手前（手順54）まで行いました。

分解後、左右の基盤をつなぐケーブルが断線していたため、そこが原因だと思い購入し交換しました。

一旦組み上げた直後は画面が付いたのですが、喜び勇んで再度組み直した後（ネジ類が仮止めだったため）、上記の状態になってしまいました。

• 左右の基盤をつなぐケーブルが刺さるZIFコネクタの目視確認（おそらくピン折れ、焦げなどはなし）
• ZIFコネクタのラッチが閉まっていること
• 効かないボタンの接点を無水アルコールに浸した綿棒で掃除

• ドライバーセット（Y00, PH000含む）
• 無水アルコール
• ピンセット
• はんだごて（100V 20W）
• テスター

よろしくお願いします。

初めての質問失礼します。

現在の状況としては、画面下に「緑色の帯」が出るといった状況です。

下側を軽く押すと、圧力によってか緑色の帯が出てきます。

また、再起動することによってなぜか直ります。

ハードウェア的要因かソフトウェアなのかわかりません！

ご回答お願いします。

Excuse me for asking a question for the first time.

The current situation is that a 'green band' appears at the bottom of the screen.

When I lightly press the bottom part, the green band appears, possibly due to the pressure.

Also, for some reason, restarting fixes it.

I don't know if this is a hardware or software issue!

I would appreciate your response.

After installing the new battery and completing the calibration charge cycles, I tried playing The Wind Waker HD. However, an error screen appears from time to time and remains visible for a few seconds. It flashes on and off so quickly that I had to record the screen and pause the video in order to read the message.

The message says that the connection to the console has been lost and recommends charging the GamePad. It does not always appear at the same frequency: sometimes I can play for fifteen minutes without interruptions, while other times it appears over 20 times in five minutes.

I tested the old battery, and the message does not appear when I use it. Is there any solution?

Thank you.

Hello, everyone. I'm writing to share the latest news so it's on record to help more people.

I contacted iFixit support and received the following response:

We do apologize for the error message you are seeing with the Nintendo Wii U GamePad Battery you received from us. It sounds like there might be a loose connection, we kindly ask that you double check the connector to ensure it is fully seated. Also, be sure to not pull the connector by the cables, as this can cause a loose connection.

As this is an aftermarket battery, the message appearing may be the equivalent of newer devices stating that a "non-genuine part has been installed and will not charge properly" - which is a frequent occurrence with aftermarket batteries. They still function correctly though, despite the error messages. That is simply the device not recognizing the chip that is paired to the mother/logic board in the device that the OEM batteries contain.

That said, if you still wish for a refund, we can do that. Or, we can try a replacement to see if that will resolve the issue.

I've checked everything, and the battery doesn't seem to be damaged, sadly, the problem persists and is very annoying. Even though I'm tempted to try the other model, I've requested a refund and I am going to use the console plugged in with the charging cable. If this starts to become a problem, I'll do a research looking for the most compatible battery.

It is very annoying since I play a lot of RPGs on it and I'm afraid I'll lost a hours of farming if it turns off when the battery is finally runs dry. Has anyone been able to solve this issue?

I ordered a new right rail from eBay. I thought the rail might be the problem . I replaced it successfully but no change. If anyone has an idea i would appreciate it.

The first and 3rd images are of my L button, which isn't broken. They're there for quick reference.

not black like it was turn off but black we definitely see that it is turn on but won't show anything. (backlight working probably?)

I tried to hold the power 10 seconds and wait but the only image i can see is when I push the power button when it's on and it asks you if you are sure if you want to turn it off. From there, and from there only, I can push the home button and it shows the white screen telling you you're going to the home screen. but it is stuck there and won't go to the actual home screen.

I want to know what exactly is the problem here and if you know how to fix it i would be grateful.

thank you
