Sony CG-FX120K User Manual
Using the computer in low temperature conditions may produce a residual
image on the screen. This is not a malfunction. When the computer returns to
normal temperature, the screen returns to normal.
The screen becomes warm during operation. This is normal and does not
indicate a malfunction.
The LCD is manufactured using high-precision technology. You may,
however, see tiny black points and/or bright points (red, blue, or green) that
continuously appear on the LCD. This is a normal result of the
manufacturing process and does not indicate a malfunction.
