Power Supply

9.2.1 Introduction
The 42" version is equipped with a FHP PDP whereas the 50"
version is equipped with a SDI PDP.
The SDI PDP (50" version) comes with a buy-in supply unit,
which makes it a "black-box" for Service. When defective, a
new panel must be ordered and after receipt, the defective
panel must be sent for repair.
This Power Supply delivers the following supply voltages to the
chassis:
• +12V
• +8V6
• +5V2
• +5V.
The FHP PDP (42" version) comes with a Philips serviceable
supply unit. This Power Supply Unit delivers the same voltages
to the chassis as the SDI Supply Unit. In addition, this unit
delivers +75 to +90 V (adjusted per display) and +50 to +65 V
(adjusted per display). For a (more) detailed description see
the FTP2.2 E manual.
Main difference with previous sets is that parts from the FHP
Supply Unit (42" version) are transferred to a new panel, the
Platform Supply Panel. In the 50" version with SDI panel, this
Platform Supply Panel is not present.
For a (more) detailed description of the on-board DC/DC
converters see the BP2.xU manual.
