I fixed one!
Believe it or not you only have to remove 3 screws to pull the LCD display power supply board.
2 metal tabs hold it in place. you have to bend, or, "reform" them to get the board out.
Once the power supply is removed, use a stiff nylon brush, brass will do but be extremely careful, and remove the excessive flux you will find.
Under a magnifier I found one of the solder points for the heat shield ( ground path) was broken. A slight squeeze to the box revealed it.
To add, I found one of the tiny gold color surface mount capacitors ( in line with an 832 and 332 resistor) didn't seem to be soldered well. I also cleaned up what I thought were some cold solder joints on some lead through components.
This assembly was soldered on a wave solder machine. IMO you are highly likely to fix the no display issue by giving it a go over.
