Re: Samsung 2243sn black screen. There is no backlight.
There is a method of hot flashing. It is necessary to warm up the cpu to 400 C. And he himself must throw off the dump from the cache in mx25L1005. But I installed another cpu from the donor, since the old one crashed.

And yes ... after soldering the cpu, the backlight appeared and when the vga was connected to the laptop, there were horizontal stripes. I think the firmware has crashed. A test without a connection is a rectangle R G B.Leave a comment:

Monitor Samsung 2243SN black screen blue LED on. The power supply board is ok. Gives out all declared currents. Main control board bn91-04248u cpu replaced MagicColor SE718m-LF, SE859MH was defective. The firmware has gone. Does anyone have a bios dump?Last edited by Vitamin4ig; 04-17-2022, 11:45 AM. -
