PHILIPS PHILIPS SERVICE AND QUALITY/TRAINING P8 POWER SUPPLY AND SIGNAL FLOW P H I L I P S PHILIPS TECHNICAL TRAINING/QUALITY ONE PHILIPS DRIVE TRAINING TECH PO BOX 14810 KNOXVILLE, TN 37914-1810 PHONE: 865-521-4397 FORCE TRAIN FAX: 865-521-4818 MANUALS EMAIL: [email protected] Introduction The P8 chassis is designed for the 2003 model year and is a step-down version of the R8. The pri- mary difference is the microprocessor. The P8 uses a "Painter" instead of an "OTC". Chassis architecture consists of a main board, referred to as the Large Signal Panel (LSP), a small- er, completely shielded, Small Signal Board (SSB) that is mounted on the LSP via an 80-pin Sim connector, a PIP/DW panel, and a 3D Comb Filter board. P8 Architecture AV4 Main Tuner AV1 - AV2 ComPair Jack AV1, 2, 4 and Tuner The set is designed to accept RF, Component, and Composite signals utilizing NTSC, Progressive, or 1080I (YPbPr) formats. It is available in two sizes: 30" and 34". A line doubler is used to convert NTSC inputs to a progressive scan format. There are four I/O (Jack Panels), referred to as AV1, AV2, AV3, and AV4. These jack panels offer numerous inputs and outputs. AV4 is used specifically for High Definition Progressive Scan or 1080I component input. These inputs can be either RGB or YPbPr type. There are two versions of this chassis. The single tuner and two-tuner versions. When two tuners are used, the second tuner is located on the PIP/DW board and is only used for reception of the PIP signals. The Audio circuitry consists of an MSP type audio demodulator/processor, a 15-watt (x2) Class "D" audio amplifier, and a headphone amplifier. P8 Chassis Rear View Video Paths The P8 chassis has several video input/output connections (also with audio connections). Figure 1 - Block AV3, the Side Jack panel, provides connections for CVBS and Y/C (SVHS) inputs. This panel is located on the left rear side of the cabinet (looking at it from the rear). AV3 Closeup from Rear P8 Service Position AV1 is mounted on the rear of the Large Signal panel (LSP) and provides connections for CVBS, RGB, and YUV inputs. AV2 is also mounted on the rear of the LSP and provides CVBS and YC (SVHS) inputs and a CVBS, Monitor output. AV4 is located on the High Definition Jack panel interface board and provides for YPbPr/RGB (HD 2fH) inputs. This chassis is capable of DW
