What s the matter that MP4 won t turn on, and what is the reason why MP4 files won t open?

Most likely, it was poisoned, so format it first. If the above phenomenon still occurs, you should get in touch with the dealer as soon as possible to get the best solution.

Another way is to upgrade the MP4 system after formatting.

On the one hand, the quality is not good, and on the other hand, it may be poisoned.

The quality of things now is really bad.

So when you buy it, you must look at the after-sales service.

I've also encountered this situation.,It's the machine crashed.,No need to format.,Just get to the place where you can repair mp4 and the management will fix it for you.,But it's best if the repair period hasn't passed.。 I spent 10 yuan when I went to fix it. You can check it out.

Poisoning is unlikely, it should be a hardware problem, go to repair and see Sa.

The switch contact is not real, it may also be other reasons, go to the repair station to see, one or twenty yuan should be able to repair.

Little things, the switch is broken, the same as mine, just one yuan, solve the problem.

It should be a virus, use antivirus software to detoxify.

There are two possibilities for MP4 files to not open:

The solution is simple:

1. Restore your phone's system. After backing up important files, contacts, etc., restore the factory settings, and it is generally normal.

3. If the above method is invalid, it means that the MP4 file is damaged during recording. It is usually caused by the overheating of the mobile phone or the poor quality of the memory card. There's no way around this.

MPEG-4 is mainly used for network streaming, CD-ROM and voice transmission, MPEG-4 includes most of the features of MPEG-1 and MPEG-2 and the advantages of other formats, and adds and expands support for virtual reality model languages.

The file in windows,Displayed as a square white surface,It's out of association.,That is, I don't know what program sequence this file is associated with.,Double-click and can't open.。

There are two possibilities for this scenario:

The solution is simple:

1. Look at the folder to put mp4 and put it in a folder called music.

2. And try to kill and kill MP4.

MP4 was originally an audio format that didn't have much to do with MPEG-4, just as *** had nothing to do with MPEG-3. is an abbreviation for MPEG-1 Audio Layer 3; And MP4 is MPEG-2 AAC, which is completely an audio compression format, adding new features such as perfect reproduction of stereo sound, multi-** control, noise reduction, and most importantly, MP4 achieves digital copyright protection through special technology, which is incomparable.

MP4, the format of the movie is wrong, and the resolution. This is almost impossible for MP5 to happen.

If you have been able to open the mp4 file before, then it is possible that the file is corrupted, you can try to copy the file to another computer or mobile phone to see if it can be opened to verify whether the file is corrupted.

Generally, the file cannot be opened because the computer or mobile phone lacks the relevant decoder or the file itself is damaged.
