ALIGNMENT PROCEDURE FOR M28B CHASSIS: I) Adjustment of B+ voltage

1. Apply 150-260VAC(±5V) to mains power input, and Philips standard testing pattern to RF input. 2. Adjust VR801 in STANDARD mode until voltage at TP2 (B+) is 112V ±0.5V.

II) NICAM Adjustment (for NICAM model only)

1. Apply a 38.9MHz color bar with NICAM signal to the IF input. 2. Monitor the DC voltage at pin 15 of IC1101. 3. Adjust T1101 until the voltage at pin 15 of IC1101 becomes 2.5 +/- 0.1V. 4. Then check the waveform at pin 4 and 6 of P1103 and it must show correct audio signal.

III) The alignment of RFAGC

1. Connect the detector shown below to collector of Q101. 2. Receive a grey scale signal with 70dBμV amplitude. 3. Adjust RFAGC item until the output of the detector becomes 0.8Vpp

Collector of Q101

IV) Adjustment of Sub-contrast, Sub-tint and Sub-colour for NSTC and PAL signal.

1. Enter D-mode, and connect the probe of Oscilloscope to the conjunction between R201 and P201 (B-out).

2. Apply the Grey-scale/Colour-bar (NTSC signal) to the AV input, in STANDARD status. 3. Select CNTC to adjust the sub-contrast, until that the amplitude “A” is 2.5V P-P as shown below. 4. Select COLC to adjust the sub-colour by tuning the amplitude of “a” and “d” to the same. 5. Select TNTC to adjust the sub-tint by tuning the amplitude of “b” and “c” to the same. 6. Apply the Grey-scale/Colour-bar (PAL signal) to the AV input, in STANDARD status. 7. Select COLP to adjust the sub-colour by tuning the amplitude of “a”, “b”, “c” and “d” to the

same.

V) Adjustment of Focus, Screen Voltage and Sub-brightness

1. Receive a crosshatch pattern. 2. Adjust the “FOCUS” VR on the flyback the make the picture clear. 3. Enter D-mode and press “MUTE” key and the screen will become a horizontal line. Then adjust

the “SCREEN” VR on the flyback transformer to set the intensity of the line to a minimum visible level (the line can just be seen).

4. Press “MUTE” key again and the TV will become full raster. 5. Select BRTC to adjust the sub-brightness, until that the 2nd dark bar of 8 level grey scales just can

be seen. VI) Adjustment of White balance

1. Receive a black and white pattern at STANDARD status. 2. Use a color analyzer to measure the black side of the screen. By changing the value of BB and

GB, set the reading of the color analyzer to x=284, y=299. 3. Then measure the white side of the screen. By changing the value of BD and GD, set the reading

of the color analyzer to x=284, y=299. 4. Repeat step 2&3 until you can get the correct reading for both black and white sides.

VII) Adjustment of Pincushion and Picture Width (for pure flat model only)

1. Receive a crosshatch pattern. 2. Adjust VR302 until the vertical line become straight. 3. Adjust VR303 for horizontal size.

VIII) Adjustment of Picture Geometry (PAL)

1. Apply the crosshatch pattern (PAL signal) to the RF input, in STANDARD status. 2. Select HPOS to adjust the Horizontal center. 3. Select VP50 to adjust the Vertical center. 4. Select HIT to adjust the Vertical amplitude. 5. Select VLIN to adjust the vertical linearity. 6. Select VSC to adjust the vertical S-correction.

IX) Adjustment of Picture Geometry (NTSC)

1. Apply the crosshatch pattern (NTSC signal) to the RF input, in STANDARD status. 2. Select HPS to adjust the Horizontal center. 3. Select VP60 to adjust the Vertical center. 4. Select HITS to adjust the Vertical amplitude. 5. Select VLIS to adjust the vertical linearity. 6. Select VSS to adjust the vertical S-correction.

X) Adjustment of OSD position

1. Enter D-mode and press key “1”, then choose OSDH(OSDHS) item and adjust the OSD vertical position 50HZ(60HZ).

2. Enter D-mode and press key “NOTE”, then choose the OSD1 item and adjust the OSD horizontal position(Volume bar,Picture bar,Half blue panel OSD).

3. Enter D-mode and press key “NOTE”, then choose the OSD2 item and adjust the OSD horizontal position except OSD1 item.

XI)D-mode: 1. press D-Mode ON/OFF key, and then you can enter the D-mode. 2. press VOLUME DOWN key on the unit until the volume decrease to minimum level, then press the DISPLAY key on the remote handset (don’t release the volume key) and you can enter D- mode.

Examples

1. The indicator is always light. Cannot turn it on by remote handset or local key. Analysis: We can draw a conclusion that the MCU section is not working. So the remote / local key cannot wake up the machine. Perhaps the reset circuit of MCU or the crystal oscillator causes the failure. Having checked the circuit, we find that all components of the reset section of MCU are OK. So we have a suspicion that the crystal oscillator is failure. We replace it with a new crystal oscillator, so the machine can work normally.

2. No sound, no picture blue screen in TV status The blue screen indicates that the video output and scanning circuit and MPU are all ok. The failure may exit in the section from the tuner to pin26 of TMPA8803CSN. We use an oscilloscope to observe the waveform of pin30, and the waveform is ok, but no signal input from the pin26. We check the circuit carefully and we find the emitter of Q209 is cold joint. So the TV signal cannot pass the Q209. That is the failure.

3. Power is switched on, and makes noises. No sound, no picture. First, we disconnect the power supply circuit in the position of +B and switch the machine on. We use a multi meter to measure of +B terminal. The voltage of +B terminal is OK. While connect the +B power supply, we measure the +B again, and we found the voltage is 0V. There must be something wrong with the horizontal power supply circuit, which is supplied by the +B voltage. Having checked the horizontal output triode, we find that there is a short between the collector and the emitter of Q402. The defective horizontal output triode is replaced and the machine is OK.

4. The horizontal output triode is too hot. The low or heavy drive current can cause this phenomenon. The resolution of right area of the raster is low. So we make a suspicion that the low drive current for horizontal output triode make the current linearity worse. We check the horizontal drive section. The power supply for it is OK. Two 1.5W resisters in parallel compose R402. One of the twos is cold soldering, and the resistance of R402 is changed from 2.4K to 4.8K. The voltage that is added to T401 drop down, and therefore the driver current is weak. The work temperature of horizontal output triode is rising. Having re-soldering R402, the temperature of

orizontal output triode is OK.

. Sound Ok, no picture (Black Screen) he standby and working status can be changed freely. But the screen is black. Menu or picture is visible. The heater is lighting, so the horizontal scanning circuit is ok. Retrace lines are visible if we

hassis for the CRT. If there is something wrong, which make TMPA8803 not receive the FBP pulse through pin12, with the scanning section. TMPA8803 will change the RGB output to black

vel via the I2C bus automatically. At the same time, TMPA8803CSN will make the beam current mallest to prevent the screen of the CRT not be hurt by the electron beam. e check the circuit according to the clew above and find that D404 is breakdown, so the FBP

6Ge erally, this kind of failure may occur at the section of the end video amplifcurrent cannot be cut off during the traceback time because the three cathodes current is too large and the three cathodes voltage is too low. Only the failure of bias circuit can make the three cathodes not be cut off at the same time because the fail probability of the three video amplifying circuits is very small. We find that there is a short at the collector of Q510. This matter makeli

7. One vertical line on the screen The failure means that there is something wrong with the horizontal deflecting circuit and the horizontal scanning has stopped. For the traceback impulses from the primary coil of the FBT still exist, the heater voltage and EHT voltage affect the display of vertical line in the screen. We check the horiteThe L412 is heavier than the other small components, and it is suppeasy to loose to cause the cold soldering. And the deflecting current all pass R411, and R411 is blew.

8. No AV signal input First, we we checked the AV input circuit but not find anything abnormal. So we exchange TV input channel and AV input channel. The AV signal can be displayed normally. So there is something wrong with the inner circuit of Pin24 of IC201. Having replaced TMPA8803CSN,

9. Fuse blew once switch the set on If the failure happen, first we should check the rectifier circuit and the switch power circuit to find whether there are some short components. Second, we should check whether there are shorts at the horizontal outputpower supply. We checked the horizontal output triode. In addition a short happened between the collector and the emitter, there was an open inside the retrace cap C406. We can draw a conclusion that the open make the retrace time less, so the amplitude of retrace impulse increased, and broke the horizontal output triode down.

1This is a defect of tuning function not signal cannot reach the MCU. Besides the AFA/AFB circuits intergrated inside the TMPA8803, M117 includes a horizontal sync separation circuit, which issignal from the composite signal which is output from pin45 of TMPA8803. And the H sync signal input to MCU from pin62. This is a mark for MCU to judge whether the set has received a channel.

11. No PIC, no sound, no raster, remote and local key unavailable First we should check the power section. As this example, the switch power


normally, and can output a main power of 112V. We checked the second voltage regulation section, and we found that the H-Vcc ( 9V ) was about 4.5V only. As the 18V power supply was OK, we uppose that there should be a short in the load section.

and Q206 were not damaged. C030 was broken down. sWe found a short at pin17 of IC201. Q207Once we havd replaced C030 and IC201, H-Vcc was OK. Because C030 as short, the base voltage of Q206 became higer. And the voltage of H-Vcc became higher also. So IC201 was damaged.
