19.4.2 Replacing the Back-Lighting of the OP37
The
brightness of the LCD back–lighting decreases during the course of time
for technological reasons.
Increase the service life of the two fluorescent tubes by blanking the screen
(refer to Section 1
1.2).
The dif
ference in brightness between a new fluorescent tube and an old one is
clearly obvious on the screen. Replace both tubes simultaneously when one
fails. This will save having to open up the OP a second time when the second
tube fails.

. In the
case of an OP37 with STN display
, the complete display must be replaced.
