MONO MODELS VIDEO SIGNAL FLOW (WITHOUT IC751)Explanation

1. IF signal from TU101 flow through to pin 63, 64 of IC501. The video detection circuit in IC501 will be detect the video signal from IF signal and then send it out by pin 60. The video out from pin 60 will be return to IC501 again by pin 56 and we’re can call this signal is “Internal Video”

2. External video is the signal from external equipment, such as VCD, or VCR. Rear A/V (JA01) and front A/V (JA02) is same line circuit but, JA02 has the internal automatic switch on/off. When you put the A/V pluck to JA02 and JA01 in same time. The IC501 will be receive the signal and flow through to pin 54 from JA02 only.

3. Internal signal and External signal will be joint together at Video switch circuit in IC501. When the user select the input signal (by press TV/AV button on the remote control or submenu on the set) and then the video switch circuit will be select the signal follow the user selected. The signal after selected will be send to video processing circuit and pin52 (video out for JA01)

4. After video processing circuit complete process, the signal R, G, B will be send out from pin 12, 13, 14 of IC501 to video amp circuit before sent to CPT.

Explanation1. IF signal from TU101 flow through to pin 63, 64 of IC501. The Sound detection circuit in IC501 will be detect the SIF signal from IF signal and then send it out by pin 1. The SIF from pin 1 will be return to IC501 again by pin 3. The sound detection circuit (2nd) will be detect the audio signal from SIF and send it out to sound switch circuit and for the JA01 by pin 5 of IC501. 2. External audio is the signal from external equipment, such as VCD, or VCR. Rear A/V (JA01) and front A/V (JA02) is same line circuit but, JA02 has the internal automatic switch on/off. When you put the A/V pluck to JA02 and JA01 in same time. The IC501 will be receive the signal and flow through to pin 54 from JA02 only.3. Internal signal and External signal will be joint together at sound switch circuit in IC501. When the user select the input signal and then the sound switch circuit will be select the signal follow the user selected. The signal after selected will be send to pin 6 for the audio power amplify circuit before send the to speaker.

Explanation1. The H drive output is open collector and active low, I.e. the H-out TR should conduct during the low period of output.2. Under normal operation condition the duty cycle of the output pulse is 50%.3. To ensure a smooth start/stop behavior of the horizontal deflection and protect the H-out TR, there are 3 different condition of H-drive output.① During switch-on.The horizontal output starts with

the double frequency(31KHz) and with duty of 75%(off),25%(on).② After about 50mSec of switch-on.The frequency is changed to normal value(15.625KHz) and duty cycle to 50%.③During switching-off. Also the frequency is switched to the double value and R.G.B drive is set to Max. and after 100mSec R.G.B is set to Min. and 50mSec later the H drive is switch-off.4. The H drive pulse from the LA76931 is amplified by the horizontal drive circuit,to get sufficient base drive current for the high voltage switching TR(Q402).

Explanation1. SIF just send out from pin 1 of IC501 and through to pin 47 of IC661. Also the external audio from external equipment just send out from IC751 to IC661.IC661 will be detect FM, AM, A2 and NICAM signal from SIF signal by Multi-Standard Digital Stereo Demodulator circuit .2. When user select external signal, the internal audio (from SIF) cannot send out from pin 24, 25 of IC661 because, the IC501 has order by I2C signal and not permit the audio from SIF signal to send out.

3. After selected the audio signal, the audio signal will be separate 2 ways. 3.1 Send out to pin 30, 31 of IC661 for JA01 (audio out L/R) 3.2 Send to stereo audio processing circuit in IC661 for adjust the quality of sound, such as Equalizer, Balance, Turbo sound, SSM etc.

4. IC661 pin 24, 25 just send the audio signal out to IC601 for amplify before sent the final audio signal to speaker.

1) Turn on the switch power of the set and then Iin1 will be maximum high (Voltage drop on pin4 of IC801 = 18.4V) for a moment. In this time V1 ≈ 115V, V2 ≈ 5V (5V St-By operate), V3 ≈ 0.5V, V4 = 0V, IFB ≈ 1.7V and pin29 (power) of IC501 = 0V. And then IC801 will be operating to stand-by mode and still for about 4.12s (T1). Also the voltage drop on pin4 of IC801 at T1 = 11.3V

2) After time of T1 finished, pin29 (power) of IC501 active = 5V, Q813 operate, IC lower, IFB lower too. In this time IC801 is operate mode, T803 has induce from pin14 to pin1, and then Iin2 flow through D801 to pin4 of IC801. So the voltage drop on pin4 of IC801 ≈ 16.1V (T2) until the switch power off (unplug).

At the first time of pin29 (power) of IC501 active = 5V, IC804 supplier the 9V (V3) to corrector of Q301, C308 coupling the V3 to ground for a moment, after that V3 is continuously increasing, but in that time V4 continue immediately high (H-output circuit operating), and then Q301 operate, V3 pass to ground (0V), Q16 cannot operate. The set to be continuously operating.

L217 Explanation1. IF signal from TU101 flow through to pin 63, 64 of IC501. The Sound detection circuit in IC501 will be detect the SIF signal from IF signal and then send it out by pin 1. The SIF from pin 1 will be return to IC501 again by pin 3. The sound detection circuit (2nd) will be detect the audio signal from SIF and send it out to sound switch circuit and for the JA01 by pin 5 of IC501. 2. External audio is the signal from external equipment, such as VCD, or VCR. Rear A/V (JA01) and front A/V (JA02) is same line circuit but, JA02 has the internal automatic switch on/off. When you put the A/V pluck to JA02 and JA01 in same time. The IC501 will be receive the signal and flow through to pin 9 from JA02 only.3. Internal signal and External signal will be joint together at sound switch circuit in IC501. When the user select the input signal and then the sound switch circuit will be select the signal follow the user selected. The signal after selected will be send to pin 6 for the audio power amplify circuit before send the to speaker.

Explanation1. The H drive output is open collector and active low, I.e. the H-out TR should conduct during the low period of output.2. Under normal operation condition the duty cycle of the output pulse is 50%.3. To ensure a smooth start/stop behavior of the horizontal deflection and protect the H-out TR, there are 3 different condition of H-drive output.① During switch-on.The horizontal output starts with

the double frequency(31KHz) and with duty of 75%(off),25%(on).② After about 50mSec of switch-on.The frequency is changed to normal value(15.625KHz) and duty cycle to 50%.③During switching-off. Also the frequency is switched to the double value and R.G.B drive is set to Max. and after 100mSec R.G.B is set to Min. and 50mSec later the H drive is switch-off.4. The H drive pulse from the LA76931 is amplified by the horizontal drive circuit,to get sufficient base drive current for the high voltage switching TR(Q402).

AV / RF ST. MODELS VIDEO SIGNAL FLOW (WITH IC751)R

760

Explanation

1. IF signal from TU101 flow through to pin 63, 64 of IC501. The video detection circuit in IC501 will be detect the video signal from IF signal and then send it out by pin 60. The video out from pin 60 will be return to IC501 again by pin 56 and we’re can call this signal is “Internal Video” 2. IC751 is service switch for the video/audio signal from the external equipment. All of the external signal will be flow to IC751 but, only one signal from external equipment can be out from IC751.IC751 just receive the command order form IC501 by mode A and mode B (pin 11, 13 of IC751). When the user select the input signal (by press TV/AV button on the remote control or submenu on the set) and then the video switch circuit will be select the signal follow the user selected. The signal after selected will be send to pin 54 of IC501 (external video input).3. DVD Y, Pb, Pr just flow to IC501 at pin 48, 49, 51 directly.4. The next step of video processing it’s just like video processing in mono model step 3 and 45. The command order from IC501 to IC751 (mode A & mode B) just like table 1 data.

2) After time of T1 finished, pin29 (power) of IC501 active = 5V, Q813 operate, IC lower, IFB lower too. In this time IC801 is operate mode, T803 has induce from pin14 to pin1, and then Iin2 flow through D801 to pin4 of IC801. So the voltage drop on pin4 of IC801 ≈ 16.1V (T2) until the switch power off (unplug).

At the first time of pin29 (power) of IC501 active = 5V, IC804 supplier the 9V (V3) to corrector of Q301, C308 coupling the V3 to ground for a moment, after that V3 is continuously increasing, but in that time V4 continue immediately high (H-output circuit operating), and then Q301 operate, V3 pass to ground (0V), Q16 cannot operate. The set to be continuously operating.

3) In that case of Open circuit (H-output circuit cannot operating), V4 only high a moment and then V4 = 0V. And Q301 cannot operate, V3 increasing ≈ 1.5V (Max = 3.4V), Q16 operate, V2=0V and then the set return to st-by mode again.

4) In that case of Short circuit (Over current flow). The voltage drop on FR403 high, and then Q403 operate, IL2flow, Q16 operate, V2=0V and then the set return to st-by mode again.
