          I would recommend that you make a bios backup before trying to flash another one.If you have any problems post your backup.

            First I check hardware problems. It charges, but not always. When i find the time, i will check all connections and solder joints.

                Thanks for the help.
                I found a burned part, chich is not changable. My customer got a used mainboard.
                The old board is now mine and works as PC under my TV.

                      I don't have a copy of the bios, I lost it, can my problem be solved if I don't have a copy of the bios?

                      My serial number: MP19KZTZ

                        Is the serial number so important? I would flash the chip with a good file.

                          Someone who can help me, I don't know which region me to use since I don't know which one had the original file, there is a random blue screen, it takes approximately 20 seconds to give an image, I already tried several regions and it is the same in all of them, open a way to know which region to put?
