2.2.2.8 POWER MANAGEMENT
The power consumption of UOC3 is ;
Only 3,3V_Stb is necessary for the start-up. IC internally produces 2,5V and 1,8V at the Standby mode. After start-up necessary 1,8V are produced by external regulators. So, we have 3,3V_Stb, 5V, 5V_Stb and 1,8V. for UOC3. We don't have 8V. even for audio outputs (1,2V RMS achieved with 5V). All the voltages are produced by SMPS except 1,8V. RESET :
1V8 digital and 1V8 analogue are produced by using 2V5 DECDIG-signal. DECDIG-signal is given
11
to base of Q108 Transistor and base of Q114 Transistor. The collector voltage becomes 1v8. When the +3V3_stb voltage decreases below the 2V6 Q110 Transistor goes OFF condition so FETs become ON. Q107 FET shorts 1V8 digital to ground and system is reset condition. Another reset condition becomes when the S_Reset port is active. While S_Reset port is active, FETs become ON. 1V8 digital is shorted to ground. All the supply architecture of the UOC3 is as follows;

Differential vertical drive signals; resistor network at inputs are chosen CF type to minimize temperature sensitivity of TV set. Those resistors can be changed to MF type in case of heat run failure. Power resistor R633, R634 values will change according to CRT sizes.
20
21
2.2.3.3 CRT Board
TDA6108AJF is used as RGB amplifier. Main feature of that triple amplifier is the increased fixed gain of 81. It's 8 MHz. Bandwidth at 100Vpp video signal makes it enable to use in all 50Hz. TV
applications.
22
CRT board have single and double focus CRT socket options. There are CC type 1,5K series flash current limiting resistors (R903, R904, R905) on the RGB lines. In addition to resistors BAV21 clamp diodes (IC901,IC902,IC903) are introduced. Spot Killer circuit pulls G1 to 200V by Q700 at turn off instant. BSVM amplifier circuit modulates the beam to have sharper images at the adges of CRT. Basicly, it amplifies the software delayed controlled BSVM signal and apply it to BSVM winding of neck.
2.2.3.4 ROTATION
PWM rotation output of UOC3 is first converted to DC then applied to rotation circuit. OPAMP LM358N (IC600) and medium power transistors (Q601, Q602) performs DC amplification necessary for rotation coil.
23
2.2.3.5 X-RAY PROTECTION
This circuit is used to protect the system X-ray caused by HV. While Anode voltage is bellow 33kv, T1 is off due to 80 volt because BE voltage of T1 becomes negative. While Anode voltage is above 33 kv. 80 voltage increases, it becomes approximately 90 volt. At that condition T1 is ON due to 90 volt because BE voltage of T1 becomes positive, so it drives protection.
2.2.3.6 DYNAMIC FOCUS
E/W injection signal is converted to sinus shape after it passes LC circuit. Then the signal is amplified via coil and applied to Dynamic focus.
24
2.2.3.7 SCREEN & FOCUS SHORT CIRCUIT PROTECTION
Above circuit is used for protection against screen & focus grounding. Basicly the base of PNP transistor Q609 is connected to screen&focus potentiometer of FBT, in another words FBT focus pack is connected to ground via R654. The voltage at the base of that transistor is normally higher then the zener voltage at the emitter. When any short circuit occurs at focus or screen the base voltage is decreased to a value lower then zener voltage, that forces transistor to conduction and trigers another circuit which will force UC to protection mode. In protection mode LED becomes RED and remote control does not work.

AK49 CHASSIS MANUAL ADJUSTMENTS PROCEDURE
Before starting with the alignment procedure, make sure that all the potentiometers on the chassis and also screen and focus pots are in the medium position.
3.1. SMPS B+ ADJUSTMENT
Prior to first run of TV chasis , FBT screen and focus potentiometers should be set to middle positions then B+ voltage is measured. If this value is different from the list below ;VR800 is adjusted to specified value below.
SYSTEM VOLTAGE
145 V±0.5V 145 V±0.5V
TYPE OF CRT
32" 16:9 RF Panasonic W76EKW10X21 28" 16:9 RF Thompson THO021X131
3.2.AFC ADJUSTMENTS
AFC is automatically adjusted from software, when f (IF) is selected 38.9MHz for negative modulation and 33.9MHz for positive modulation from the service menu.
3.3.
FOCUS ADJUSTMENTS
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. For double focus tubes,there are two focus potentiometer; each of them should be adjusted for optimum focus on the screen
41
3.4 SCREEN ADJUSTMENTS
For screen adjustment VG2 item should be selected at the service menu. then the screen potentiometer is gently adjusted until the "STABLE IN" sign appears.

HBL
When the reproduction of 4 : 3 pictures on a 16 : 9 picture tube is realised by means of a reduction of the horizontal scan amplitude the edges of the picture may slightly be disturbed. This effect can be prevented by adding an additional blanking to the RGB signals. The blanking pulse is derived form the horizontal oscillator and is directly related to the incoming video signal (independent of the flyback pulse). This blanking is activated with the HBL bit.
