I have an iPod Touch 4th gen that does absolutely nothing other than show a white screen when the home button or the power button is pressed. I have never opened it up before, the screen is the original, and iTunes doesn’t detect it. I can’t even do a hard reset. Edit - before I forget, no, I haven’t dropped it either.
any cause that you can tell or just randomly happened one day? I have had a water damaged iPod touch do this. That is what i would check for first if there is no physical damage that you can see. I doubt it is under any warranty at this point, GO ahead and try to open it up if you’d like. The 4th gen is not very fun to work on and requires soldering to remove the battery :( Best of luck to you!
Probably a poor connection or static/grounded screen. Open and inspect. Disconnect the battery and LCD. Reconnect and test before putting it back together. Try a new LCD if that doesn’t work but a replacement device might make more sense at that stage. Good luck
Put it in DFU mode (while powered up, hold home and power for 15 secs, and keep holding home for another 10), and restore it through iTunes. If it’s not detected, the charging connector is likely loose or disconnected.
