I would first check the charging port for dirt or debris. You said you used multiple chargers and cables. Did you use brand new cables or just ones that worked with other devices. I ask this because I have had phones that would get loose and would only work with new cables, even though the same old cable would work with other devices with out trouble.
It is an antique from 2008, just send it to your telco and ask for a new phone. It isn't worth even trying to fix. No one uses Flip Phones in 2023 apart from in Third World countries. It has an internal short circuit. You can try a Factory Reset, but that is about it.
Take your time remembering it.
A hard reset is the only next solution. You hold the buttons pressed (different ones for each model) and should see the recovery screen. There you can go back to factory defaults. It means each update, self chosen app and your own files will be lost! Files sometimes have kept backups in the cloud and your apps can be reinstalled from the app store.
If the Samsung flip cover screen is permanently white, it could indicate a hardware issue. Here are a few possible causes and solutions you can try:
Insufficient Battery or Power Issues: Make sure that your device has enough battery power by charging it for a while. If the battery is completely drained, it may cause the screen to display a solid white color. Try using a different charging cable or power outlet to eliminate any charging issues.
Software or Firmware Problem: If the software or firmware on your Samsung device is corrupted, it can lead to various display issues. Try performing a soft reset by removing the battery (if possible) and then reinserting it after a few seconds. If this doesn't work, you may need to perform a factory reset. Keep in mind that a factory reset erases all data on your device, so make sure to back up your data first.
Physical Damage: If your device has been dropped or exposed to water or other liquids, it may have caused internal damage to the display. In this case, you will likely need to take it to a professional repair service or contact Samsung support for further assistance.
Display Connector Issue: It's possible that the connection between the display and the motherboard or the flip cover is loose or damaged. If you have experience with electronics, you can try opening the device (if possible) and reattaching or replacing the display connector. However, if you're not familiar with this kind of repair, it's best to seek professional help.
If none of these solutions work, it is recommended to contact Samsung support or take your device to an authorized service center for further diagnosis and repair.
Try putting it on a wall charger and leaving it for as long as you can you could have a problem with your battery or try pressing and holding the volume up down and power button all three at the same time
