Never expose the set to rain or water. If the set has been exposed to rain or water, unplug the set from the wall
outlet and refer servicing to qualified service personnel.
12. Choose a place where light (artificial or sunlight) does not shine directly on the screen.
13. Avoid dusty places, since piling up of dust inside TV chassis may cause failure of the set when high humidity persists.
14. The set has slots, or openings in the cabinet for ventilation purposes, to provide reliable operation of the receiver, to
protect it from overheating. These openings must not be blocked or covered.
Never cover the slots or openings with cloth or other material. Never block the bottom ventilation slots of the set by placing it on a bed, sofa, rug, etc. Never place the set near or over a radiator or heat register. Never place the set in enclosure, unless proper ventilation is provided.
PROTECTION AND LOCATION OF YOUR SET
15.1. If an outside antenna is connected to the television set, be sure the antenna system is grounded so as to provide some protection against voltage surges and built up static charges, Section 810 of the National Electrical Code, NFPA No. 70-1975, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrode, and requirements for the grounding electrode.
15.2. Note to CATV system installer : (Only for the television set with CATV reception)
This reminder is provided to call the CATV system attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
16. An outside antenna system should not be located in the vicinity of overhead power lines or other electric lights or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.
17. For added protection for this television set during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage due to lightning and power-line surges.

Alignment Procedure of M123A Color TV
1. FLOWCHART OF ALIGNMENT PROCEDURE
2 Adjustment of B+ voltage
1) Apply 120VAC(±5V) to mains power input, and Philips standard testing pattern to RF input.
2) Adjust VR830 in STANDARD mode until voltage at TP2 (B+) is 108V ±0.5V.
3. RF AGC adjustment Observe monitor the collector waveform of Q101 with the probe of Oscilloscope as illustration below. Select channel 2 (>70dB) from the antenna input. Enter D-mode, select menu6 to adjust RFAGC item until the monitor peak value to 0.8V

4. Screen & Focus voltage adjustment
Apply pattern signal in normal status, enter D -mode, press “TV/AV” button to turn
off the vertical output.
Adjust the SCRREEN switch on the flyback transformer to make a horiz ontal
shining line just visible on the screen.
Turn on the vertical output, adjust the “FOCUS” on the flyback transformer to
obtain the optimum focus.
5. White balance adjustment
1)Apply the black and white pattern in normal status;
2)Alignment of normal color temperature
Change Color Temperature to normal status Use a color analyzer to measure the black side of the screen. By changing the
value of RC, GC and BC, set the reading of the color analyzer to X=285, Y=295.

Use a color analyzer to measure the white side of the screen. By changing the
value of GD, BD, set the reading of the color analyzer to X=285, Y=295.
Separately set the brightness and contrast from min. to max., repeat the step 2 and
3 until the reading of the color analyzer is correct.
3)Alignment of warm color temperature
Change Color Temperature to warm status Use a color analyzer to measure the black side of the screen. By changing the value
of RC-W, GC-W and BC-W, set the reading of the color analyzer to X=294, Y=303. Use a color analyzer to measure the white side of the screen. By changing the value of GD-W, BD-W set the reading of the color analyzer to X=294, Y=303. Separately set the brightness and contrast from min. to max., repeat the step 2 and 3 until the reading of the color analyzer is correct.
4)Alignment of cold color temperature
Change Color Temperature to cold status Use a color analyzer to measure the black side of the screen. By changing the value
of RC-C, GC-C BC-C , set the reading of the color analyzer to X=279, Y=286. Use a color analyzer to measure the white side of the screen. By changing the value of GD-C, BD-C, set the reading of the color analyzer to X=279, Y=286. Separately set the brightness and contrast from min. to max., repeat the step 2 and 3 until the reading of the color analyzer is correct Note: Provided the production line is equipped with the self- White balance adjusting equipment, white balance of M123A chassis can be adjusted automatically as following: Press “I2C BUS” button under factory mode, the TV set will adjust automatically.
6. Adjustment of Sub-brightness,
Apply the Grey-scale/Color bar (NTSC signal) to the AV input, in normal status. Select BRTC to adjust the sub-brightness, until that the 2nd dark bar of 8 level
Grey scale just can be seen.
