ACTION
We have registered the Touch Panel LED PWB and Bezel Unit as service parts.
There are two types of LED mounted to the Touch Panel LED PWB; one is by ROHM
and the other is by Sharp.
[Caution]
When replacing the Touch panel LED PWB, ensure NOT to mix the PWB with LED by
ROHM and Sharp.
If these PWBs are mixed, the machine may not work properly due to the variance in
characteristics of LED.
Similarly, pay attention on which LED is mounted to the Touch panel LED PWB when
replacing the Bezel unit BTM and Bezel unit R. Ensure the PWBs with LED by
different manufacturer are not mounted together.
* In cases where different types of Touch panel LED PWB have already been used
since repair etc. and the units has not had any problem, use the unit as it is without
replacing the PWB.
There is no requirement to distinguish Touch panel sensor PWB and Bezel unit Top /
Bezel unit L with Touch panel sensor PWB because they are compatible.
