CRT burns
On repacking
When a static picture of a computer, etc. is displayed for more than about
an hour, a CRT burn may result. This means that an after-image
impression of the static picture remains on the screen even after the picture
has changed. If it is necessary to display the same static picture for more
than an hour, we recommend that you set the CONTR (contrast) control to
the lowest setting.
Also, when a picture of different size is displayed beyond a certain length
of time, an after-image impression of the frame of the smaller picture may
be burnt on the screen (such as displaying a 16:9 wide size picture on a 4:3
screen). To avoid this, we recommend that you use the same picture size
when possible. However, if it is necessary to use a different picture size,
set the CONTR (contrast) control and the BRT (brightness) control of the
smaller picture to the lowest setting possible. This will minimize the risk
of creating an after-image impression.
If the CRT burns, it must be replaced. In this case, refer to the warranty
provided with this unit. Consult your Sony dealer or Qualified Service
Personnel.
Save the original shipping carton and packing material; they will come in
handy if you ever have to ship your unit. For maximum protection, repack
your unit as it was originally packed at the factory.
