The successor of the FTV1.5 is the FTV1.9, which had to be

cheaper,and had to make as much as possible "re-use" of

PWB's from the FTV1.5.

Personal notes

It is built around an E-Box (= Receiver Box) and a 42" Monitor

(= Display Box). Within the Monitor a Fujitsu Plasma Display

panel - version 5 - is used.

For the FTV1.9, the Monitor can be used in two applications.

• Stand-alone configuration, monitor is connected to a PC or

a laptop

• TV configuration, where the monitor is connected to the E-

box.

The Monitor is a separate device, which can also be sold and

serviced separately.

The monitor, as a stand-alone unit, can be serviced by using a

test pattern coming from the PDP-LIMESCO panel on the

monitor itself or via a PC/laptop by using ComPair via the

ComPair connector.

FTV1.9 Family has been set up for Europe, USA, Asian and

LATAM markets.

The Europe type consisting of 1 version, having no diversity.

The panels are:

1. VsVa supply. At this panel all the supply voltages will be

generated for the display itself, the electronics of the display

and our PCB's. This panel contains also the fan control and

the protection circuits.

2. PDP Discharge Panel. Temporarily used in the DEM-

models of the FTV1.9. In the final models this panel is either

going to be integrated into the VsVa panel or is going to be

re-designed as a separate new panel. The function of this

panel is to discharge the big capacitor of the Vs-supply and

the Va-supply (minor reason). If these capacitors are not

discharged it can take up to 60 seconds before the set re-

starts after turning it OFF and ON again.

3. Audio amplifier. This panel is almost the same as the GFL

audio amplifier. Some small changes have been made like

other plugs, deleting a switch and external speaker

connectors and an adaptation of the outlines, just to mount

the panel at the backside of the Monitor.

4. Preconditioner. At this panel the mains input and mains

output (to connect the E-Box) is located. After the mains

input, the mains filter is placed. The panel contains also the

preconditioner. This is an auto voltage function from 95V ...

264VAC in to 380VDC out and the standby supply for the

µ P and the NVM.

5. AV Control. At this panel the VGA, audio and control (UART

or DDC) signals enter the Monitor. These signals will be

buffered and are available at the output of this panel for

feedthrough (except the control signals). The same signals

will be fed to the Audio part (including an (optional) audio

delay to correct the timing between video and audio) and to

the video control IC to control the RGB signals. Also the µ P

for the panel control in the Monitor is located on this board.

The audio filters for the high and low/medium signals are

also located on the AV Control board.

6. PDP LIMESCO. This panel converts the analogue video

after gamma correction to a digital video signal, which is

connected to the PDP itself. The OSD generator is located

at the PDP LIMESCO, close to the LIMESCO IC for the

insertion of digital OSD information. The LIMESCO IC is

responsible for the scaling of the signals of the various

standard TV standards, VGA formats at this board. The H

and V position is corrected by an EPLD.

7. YUV YC input panel. This board gives the possibility to

attach several video formats to the stand-alone display. It

also has one stereo audio connection.

• Video input signals:

– YUV on three CINCHES (Y, Cb, Cr).

– YC on Hosiden connector (SVHS).

– CVBS on CINCH.

– CVBS on BNC.

• Audio input signals:

– L and R on 2 CINCHES.

• Output signal (AV Control):

– RBG-signal.

– H-sync and Vsync signal.

– L and R audio signal.

8. LED Display panel. At this panel, the LED's and the IR-

Receiver is located.

9. Switch Display panel. At this panel, the low power mains

switch is located. With this switch a relay is controlled to

switch ON and OFF the monitor

1. Disconnect Fan Supply cable from connector FD07 in the

upper left corner [1].

2. Remove the 7 fixation screws of the panel [2].

3. Place panel on the 2 hinges, which are located near the

right corners of the panel [3].

4. Use the mechanical service part (extension cable

assembly, 12NC: 3122 785 90006) to extend the Fan

Supply cable [4].

5. The copper side is now accessible from the left.

1. Place the Display Box in the service stand via 2 reinforced

cushions (order code: 3122 126 30181).

2. Remove the 9 fixation screws of the rear cover.

3. Remove the rear cover (during removal push it slightly

upwards).
