2.2.2.1. UOC-II (ULTIMATE-ONE-CHIP)
UOCII is composed of microcontroller, video proccessor, sound proccessor and IF blocks. The various versions of the TDA955X H/N1 series combine the functions of a video processor together with a microcontroller.The ICs are intended to be used in economy television receivers with 90 and 110 degree picture tubes. The ICs have supply voltages of 8V and 3.3V and they are mounted in a QFP 80 envelope. The features are given in the following feature list. FEATURES TV-signal processor · · · · · · · · · · · · · · Multi-standard vision IF circuit with alignment-free PLL demodulator Internal (switchable) time-constant for the IF-AGC circuit The QSS and mono FM functionality are both available so that an FM/AM TV receiver can be built without the use of additional ICs The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that the external band-pass filters can be omitted. The FM-PLL demodulator can be set to centre frequencies of 4.74/5.74 MHz so that a second sound channel can be demodulated. In such an application it is necessary that an external bandpass filter is inserted. The vision IF and mono intercarrier sound circuit can be used for the demodulation of FM radio signals Video switch with 2 external CVBS inputs and a CVBS output. One of the CVBS inputs can be used as Y/C input. 2 external audio inputs. The selection of the various inputs is coupled to the selection of the CVBS signals Integrated chrominance trap circuit Integrated luminance delay line with adjustable delay time Switchable group delay correction in the CVBS path Picture improvement features with peaking (with switchable centre frequency, depeaking, variable positive/negative overshoot ratio and video dependent coring), dynamic skin tone control and blue-, black- and white stretching Integrated chroma band-pass filter with switchable centre frequency

2.2.2.6. SMPS 2.2.2.6.1. PRIMARY BLOCK

AC power applied via AC inlet, line filter components prevent chassis from incoming noise of AC line, also prevents AC line against created noises by TV. Bridge rectifier and bulk capacitor converts AC voltage to DC voltage. Applied DC voltage to primary winding is then swicthed via MOSFET by primary controller in a controlled manner. SMPS controller works on quasi-resonant PWM and gets first supply voltage from AC line (SMPS Controller supply). Controller drives MOSFET according to feedback information supplied by shunt regulator and opto-coupler, according to that information adjusts on-time of MOSFET for required power. After the start-up in normal operation mode SMPS controller is supplied by SMT. Primary block consist of following main parts, AC Inlet (PL800), Fuse (F800), Varistor (R800), Line Filter For EMC (C801,L800,C800), SMPS Controller (IC801), SMPS Controller supply for first Start-up (R807), Bridge Rectifier (D811,D813,D814,D816), Rectifier For SMPS Controller(D801), Bulk Cap (C806), Clamping Circuitry (R809,C812,C813,C817), SMT (Switch Mode Transformer) (TR800), SMT Driver MOSFET (Q800), Current Sense Resistor (R812), Protection Components for MOSFET Failure (D815,D812,R811)

2.2.2.7. DEFLECTION
2.2.2.7.1. HORIZANTAL DEFLECTION

Deflection block consist of following main parts, Horizontal driver transistor (Q600), Horizontal driver (L600), HOT (Horizontal Output Transistor) (Q603), FBT (TR600), Linearity Coil (L601), Flyback Capacitors (C611), S-correction capacitor (C622), Modulated S-correction capacitor (C623), Hdrive signal is buffered and applied to line driver transistor by a capacitor. Line driver produces necessary base currents, parallel diode to base series resistor speeds up the reverse base current. UOCII has soft-start and soft-stop features to have more safe operation. There are two base current adjustment resistors on the circuit. Collector current differs according to CRT sizes .

2.3.2. Adjustments
Geometry Adjustment: After adjusting 50Hz geometry items (between 007-011). NTSC 60 Hz geometry items (between 016-018) should be adjusted to determine NTSC 60Hz offset. NTSC offset is automatically calculated and stored in NVM. Later on, if we need to change 50Hz geometry settings, NTSC 60Hz geometry settings is automatically calculated by using NTSC offset. 16:9 mode geometry adjustment works like NTSC 60Hz geometry adjustment. If press to menu button between 007-011 or 016-018 items. New geometry setting is stored and, 16:9 mode, RGB shift and NTSC geometry automatically calculated. RGB shift offset value is stored in software. Only NTSC offset and 16:9 mode offset values are stored in EEPROM. AGC adjustment: Connect to tuner 60db broadcast and, press to blue button on AGCTO item. AGC is automatically adjusted. Screen Adjustment: When yellow button is pressed in service menu. Vertical scan is disabled and related registers are updated. Thin line will be appeared on the screen. Then the screen potentiometer is gently adjusted until the thin line will be lightly disappeared When press to yellow button again, old register values are reloaded and vertical scan is enabled. FOCUS Adjustment: TV is tuned to the signal. Then focus potantiometer (the upper pot on the rear side of the FBT transformer) is adjusted for optimum focusing drive.
