Hi everyone,
The screen (lcd) on my R40e went blank and replaced the whole assambly that i bought on E-bay. Still no picture. But on an external monitor the mashine is fine.
Replaced the lcd cable, still no picture, but on an external monitor OK.
Checked the LCD assy on another R40, it works fine.
is the video chip faulty? or has dirt on legs? could you enlighten me what's going on?
