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 Ebox. 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. Personal notes FTV1.9DE Display Box 1. Introduction 1.1 Description of used panels 3 1.1 Description of used panels VS/VA Supply PDP Discharge Audio Amplifier PDP Limesco Pre-conditioner AV Control YUV/YC Input CL 96532069_131.EPS 120899 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 DEMmodels 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 restarts 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
