A1989 black screen

Hi

I have the same problem, black screen, but because there is a burn in the flat screen itself, is it possible to implant a direct connection wire?

Use ipa alcohol and clean up each of these connectors. Some contacts are not clean on J0200. Clean up each and test again.

I am cleaning it but there are some burn on the line of backlight, so I need to repair it and need to know where the point is on the flat

You can certainly wire directly onto the SMD backlight connector(s) but you must be very good at soldering and with a steady hand. Double check your work to be sure there are no shorts to nearby connector pins. If there is a short, the high backlight voltage of 25-45 volts will enter the display low voltage pins and cause other damage.

Is it possible to clarify the location of the point where the connection will be made between the flat screen because I do not have data sheet

Hard to tell from the pics on which side of the cable is at fault. You are asking about the wiring of the cable that enters the display assembly? I think that you should be able to purchase replacement cables for the display assembly. You can check on Aliexpress.

I found the cause of the problem of the light not appearing on the screen of the device and there was a burn in the coil responsible for connecting 5 volts to the screen and I connected a light copper wire instead of the burned coil and the problem was solved Thank you who contributed with me to the topic

Well done (by those that still have great eyesight I would certainly use my 4k microscope to attempt this one.
