OVERALL SCHEMATIC OF POWER SUPPLIES The power supply to this appliance is located on a dedicated Power Supply Board. It essentially consists of two parts: - the FROSIN power supply, which delivers permanent voltages (control power supply) as well as switched voltages for any signal processing carried out on the main board, the scaler board, and optionally, the DVD board. - the resonant power supply which supplies switched VSSIN voltages for the inverter board (specific power supply circuit for backlighting) as well as +/_UA for the audio board. For models that draw a lot of power (27" screen diagonal or bigger), a dynamic power factor correction circuit is inserted between the rectified mains voltage and the resonant PS so as to reduce cos phi and the harmonics reinjected into the mains circuit. 3 The IR001 microcontroller located on the main board controls the standby output via the PO line. The latter provides switching for the 20 Volts generated by the Frosin power supply, and this voltage in turn activates three other voltages (10V, 6V, 4V). Lastly, the 4V voltage starts up the resonant power supply. The mains voltage is monitored by the microcontroller via the FROSIN power supply and the INF_POW_FAIL line. The Genesis circuit on the scaler board controls the start-up of the power supply inverter via the V On/Off line and controls backlighting brilliance via the SCV bri line.

quicker restart), and DP227 provides protection in cases of overvoltage by going short-circuit if this happens (disappearance of control current on TP220). Four unswitched voltages are developed on the secondary: - 33 Volts for the tuner power supply. - 20.5 Volts. - 10.5 Volts powering a 5V regulator for supplying the control voltage (5VSTBY). - 6.5 Volts, chosen for the secondary regulation; this is the origin of 3.3VSTBY. Secondary regulation makes use of an opto-coupler (IP251) in series with regulation circuit TL431 (IP261). A fraction of the 6.5V applied to IP261 via a divider bridge (RP261/RP462) is taken and compared with the internal 2.5 Volt reference. Any variation in the 6.5 Volts will therefore tend to modulate the current in the opto-coupler, and consequently, the instant when TP222 is switched and TP220 is blocked. An acquisition mode is provided by the use of transistor TP261. When the base of the latter is released by the AQR line leading from pin 113 of IR001, TP261 applies a 10.5V image (via DP261) to the regulator input, thus ensuring regulation of this voltage also. In the event of overload of the 6.5 Volts, a protection system short circuits the regulator and saturates the opto-coupler, thus temporarily blocking the chopping transistor.
This power supply, whose concept is in common use in the Group's products, generates the voltages required for standby mode and also delivers switched voltages for any "small signal" processing located on other boards. A mains voltage of between 190VAC and 264VAC is rectified by the DP252/253/254/255 bridge, filtered by condensers CP258/259, then applied in parallel to transformer LP253 in the Frosin power supply and the push-pull transformer in the resonant power supply (RAW_B+). The MOSFET transistor LP220 and the condenser CP220, in series with the primary of LP253, determine the primary current. The latter is kept in check by resistance RP220. The start-up current comes from a single mains phase via resistances RP257 and RP 258, via condenser CP225, and via driver transistor TP495. This will only switch when there is a charge of roughly 9 Volts or more coming from CP225, using the threshold effect of zener diode DP493, to ensure clean switching of the MOSFET transistor. Once the power supply is started up, the charge from CP225 is obtained from self-powering (winding 6/8 and diodes DP225/226). The on/off switch does not act directly on the mains voltage but simply cuts off the control current to the MOSFET transistor (connector BP253). Chopping transistor TP220 is blocked by transistors TP222/223 (on/off circuit), which short-circuit the gate/source space when they are switched. This works through the combined effect of primary current measurement (RP220 and RP231), of regulation from the opto-coupler (IP251), and of the auxiliary circuits via resistances RP238, RP293, and RP241: - RP238 and condensers CP239/438 set the minimum saturation time for TP220. - DP237 and CP237 time the new saturation of TP220, to limit dissipation by switching. - CP240 and DP240 correspond to the soft-start and mains compensation circuits. Zener diode DP233 protects the gate/source space in TP220, DP230 blocks the secondary regulation action when the charge on CP225 is too weak (promotes a

SECONDARY SWITCHING ON THE FROSIN POWER SUPPLY The order to quit standby mode is given from pin 87 of microcontroller IR001 and transmitted via transistor TR198 and connecters BP001 and BP220A. The resulting high state on line PO saturates transistors TP407 and TP205 and switches the 20V voltage when above 20.5V. This voltage will be used in the SCART section but first and foremost it is behind the switching of three other voltages: - 10V obtained from the 10.5V voltage through the intermediary of MOSFET TP204. This voltage supplies 9V and 8V for general audio and video processing on the signal board. - 6V and 4V via the IP203 and TP203 regulation circuit. These 6 Volts supply several boards, in particular the 1H/2H IV100 converter on the signal board. The 4 Volts are intended for the scaler board and starting up the resonant power supply. Two other unswitched voltages are also regulated: - 5VSTBY obtained from the 10.5V line by a similar stage to that used in the 6V and 4V: divider bridge RP415/416 compares a fraction of the output voltage with the internal 2.5V reference in regulation circuit IP202, consequently modulating the gate voltage of MOSFET TP202. - 3.3VSTBY obtained from the 6.5V via a regulator assembly which is a replica of the one described above (TP201/IP201). These two voltages are clearly intended for control. 9ROWDJHV 9 9 9 9 9 9VWE\ 9VWE\ 9a 9a 9a 9a 9a 9 9 9 9 9 7ROHUDQFHV 1RP FXUUHQW PD PD $ $ $ PD PD $ $ 3HDN FXUUHQW

FROSIN POWER SUPPLY PROTECTION CIRCUITS There is a first safety measure associated with overvoltage, which for example could happen because of a cut-off in secondary regulation. As a reminder, the primary voltage generated by self-powering and applied to condenser CP225 in this case will also increase. When it reaches 27V it will be limited by zener diode DP227, whose current starts rising. Beyond a certain threshold, the zener shortcircuits, thus removing the control current from chopping transistor TP220. The second protection system is related to possible overloading or shortcircuiting of the 6.5V voltage. At start-up, when secondary voltages are still developing, the time constant RP472/CP271 times the polarisation of transistor TP271, whose base is then short-circuited by the conduction of circuit IP271. When the voltage of the 6.5V line exceeds 3.3V, the reference input of IP271 tends to exceed 2.5V via divider bridge RP475/476, thus leading to increased conduction in this component and the continued blocking of TP271. Consequently, in normal working conditions the current in the opto-coupler is controlled solely by regulation from IP261. Now let's assume heavy overloading on the 6.5V line causes this voltage to collapse below 3.3V. IP271 will then block, thus releasing the polarisation and saturation of transistor TP271, which in turn will saturate the opto-coupler. The chopping transistor is blocked this time by on/off circuit TP222/223 and the power supply closes down.

RESONANT POWER SUPPLY This second part of the power board supplies energy to the LCD panel in order to provide power to the backlighting (inverter board) in the form of the voltage VSSIN (19 Volts); it also delivers symmetric voltages +/-UA (+/- 15 Volts) to the audio power stage. The core of the primary circuit is the integrated circuit ST L6598, which is adapted to control an AC/DC converter that uses the principles of resonance and of a halfbridge configuration. In the final stage it comprises two drivers which alternately switch one of two MOSFET transistors. The resonance circuit, which consists of the transformer primary and two condensers in series, is connected between the ground and the common point of these two transistors. The power supply source for this circuit is the primary of transformer LP253 (V_PRI of the FROSIN stage), rectified by diode DP301 and switched by transistor TP302. The start-up command signal is the 4 Volts from the FROSIN power supply, this voltage being switched by the micro-controller (PO). It saturates opto-coupler IP302, which blocks transistor TP303, thus releasing the polarisation of MOSFET TP302. On the gate of the latter, regulation circuit IP303 coupled with divider bridge RP503/504 sets voltage Vs (pin 12 of IP300) to roughly 12 Volts (10.7 Volts being the start-up voltage). The oscillator incorporated into this circuit generates triangular waves whose frequency is determined by the charging and discharging cycles of condenser CP516 (pin 3). The are the effect of currents Ifstart, Ifmin, and the charge on softstart condenser CP315 (pin 1). Ifstart is linked to RP517 (Ifstart = Vref / RP517 with Vref = 2V); Ifmin depends on RP511, RP512, and conduction in opto-coupler IP310. During the first instants of start-up, frequency is a function of the sum of currents Ifmin and Ifstart; then as the latter drops away with the effect of the charge on CP315 (soft start), the frequency does likewise and becomes fmin = 1.41/(RP511 x CP516) = 53kHz (with IP310 blocked). To sum all this up, RP511, RP517, and CP516 set the start-up frequency to roughly 100kHz. This then decreases with the soft start (~= 750msec) and drops below 53kHz to settle down at a value that depends on secondary regulation (conduction in IP310).
This triangular signal is then shaped by the logic stages to control the push-pull output, with alternate saturation of TP321 on the up ramp and TP322 on the down ramp, condenser CP325 being jointly used with the integrated bootstrap assembly to ensure clean saturation of TP322. Maximum energy will be transmitted when the control frequency is the resonant frequency of the primary circuit on transformer LP300 and condensers CP321 and CP322, because the load impedance is then lower and the peak current reaches a maximum value. Increasing the control frequency will consequently result in the lowering of this peak current and thus a reduction in transmitted energy. Since the control frequency is related to the overall resistance connected to pin 4, modulating the conduction of the opto-coupler will give rise to a modification in the oscillator frequency and thus control the energy transmitted. Secondary voltage VSSIN is regulated by comparing it via a divider bridge (RP553, RP554) with the internal reference (2.5 Volts) on regulation circuit IP351. When the charge on this line increases, the voltage tends to drop as does the current in the opto-coupler through the action of IP351. The overall resistance seen from pin 4 therefore increases and reduces the frequency of the oscillator and the control, which approaches that of resonating circuit LP300/CP321/CP322. The consequence of this, as explained above, is an increase in transmitted energy.
