Introduction The FL9.1 TV chassis is designed for the 2009 model year. The tuning system is designed to tune both antenna and cable analog and digital signals. The screen size for this chassis is 32 inches with a pixel resolution of 1366 x 768p. Whatever signal is fed to the set will be rescaled to fit the resolution of the screen.
HDMI v1.3, S-video in, CVBS in, Audio L/R in, USB (software upgrade only) The FL9.1 chassis has the Philips EasyLink (HDMI-CEC) capability. This feature has addi- tional function compared to the 2008 Philips sets. This feature is referred to as CEC in the Magnavox, Sylvania and Emerson products.

IR Board Set Back view Repair The FL9.1 chassis is designed for board level repair. To assist with troubleshooting, compo- nent level function will be discussed. The Digital Main board has the microprocessor and signal processing circuits. The HDMI and USB inputs are located on the Digital Main board.
Board Level Repair (Figure 2) The Fl9.1 chassis is designed for board level repair. Standby mode In Standby, the processor on the Digital Main board is powered by the AL+3.3V supply. This voltage can be measured on pins 21 and 22 of connector CN301 on the power supply board.
The Function (Keyboard) is hard-wired to the IR Sensor board and it to the Junction board. Only the KEY-IN1 is used for the keyboard. The KEY-IN2 is used in other chassis with a built in DVD player. IR Board Junction Board Raw DC is supplied to the Inverter board via connector CN602 on the power supply board.
Video Signal flow (Figure 3 & 4) Figure 3 The composite and S-video inputs are located on the side jack panel. These signals are fed to the the power supply on hard wired connecter CL701A. The one component input is locat- ed on the power supply panel.
The waveform to the right is the POL signal on CN3902, pin 5. The waveform to the right is the TP signal on CN3902, pin 6. The waveform to the right is typical of the ones carrying the picture information. This signal is measured on pin 8 of CN3902.
CAUTION ! Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit. NOTE: CAUTION ! : For continued protection against risk of fire, If Main Fuse (F601) is blown , check to see that all components in the power supply The voltage for parts in hot circuit is measured using replace only with same type 4 A, 125V fuse.
Power Supply (Figure 6) AC is fed the line filters and bridge rectifier. RAW DC is fed to the Inverter via connector CN602 on the power supply board and to transformer T601. The switch mode supply consist of transistors Q601 and Q602. In standby, the power supply is running in a low power pulsating mode controlled by Q634 on the secondary side.
Inverter (Figure 9) The inverter power supply is switched On by the BACKLIGHT-SW line from the digital board. The BACKLIGHT-ADJ line is fed to IC1000 to control the pulse width output of IC1000 and the brightness of the backlight. The outputs to the backlights are fed to over voltage protec- tion circuits.
NOTE: The voltage for parts in hot circuit is measured using hot GND as a common terminal. HOT CIRCUIT. BE CAREFUL. T1050 INV+16V CN1050 T1950 TO POWER CN1900 BACK SUPPLY LIGHT BLOCK Q1801,Q1802, DIAGRAM HOT-GND Q1803,Q1804 (CN602) Q1800,Q1815 SW+16V SW+16V IC1000 T1100 (PWM CONTROL)
To enter the service mode, it is necessary to press a hidden button on the remote control. As shown to the right, it is necessary to have a Magnavox remote for entering the service mode for the Magnavox and Philips models. Service mode for the Sylvania LC320SLX and Emerson LC320EMX.
The Service screen is shown to the right. Refer to Figure 11 for the service menu map. To Initialize the set which puts it in an out of box condition, press the Info button on the remote while in the service screen.
