1. SAFETY PRECAUTIONS The design of this product contains special hardware, many Isolation Check circuits and components especially for safety purposes. For (Safety for Electrical Shock Hazard) continued protection, no changes should be made to the After re-assembling the product, always perform an isolation original design unless authorized in writing by the check on the exposed metal parts of the cabinet (antenna manufacturer.
3. REPLACEMENT OF MEMORY IC 1. MEMORY IC. This TV uses memory IC. In the memory IC are memorized data for correctly operating the video and deflection circuits. 2. PROCEDURE FOR REPLACING MEMORY IC (1) Power off Switch the power off and unplug the power cord from AC outlet. (2) Replace IC Be sure to use memory IC written with the initial data values.

PURITY ADJUSTMENT WEDGE Demagnetize CRT with the demagnetizer. DEFLECTION YOKE Loosen the retainer screw of the deflection yoke. Remove the wedges. Input a green raster signal from the signal generator, and turn the screen to green raster. Move the deflection yoke backward. P/C MAGNETS Bring the long lug of the purity magnets on the short P: PURITY MAGNET...
STATIC CONVERGENCE ADJUSTMENT 1. Input a crosshatch signal. 2. Using 4-pole convergence magnets overlap the red and blue lines in the center of the screen (Fig. 1) and turn them to magenta (red/blue). (FRONT VIEW) 3. Using 6-pole convergence magnets overlap the magenta (red/blue) and green lines in the center of the screen and turn them to white.
9. DVD Part: Introduction of MTK1389E maintenance NOTE: MTK1389E is a type of LSIC for DVD decode .MTK1389E IC consists of RF,SERVO,DSP,DECODE,VIDEO DAC and AUDIO DAC. Under normal power supply conditions, the maintenance plan for MT1389E mono-chip is: first the reset circuit resets the MT1389E , after the crystal oscillator circuit gave the clock signal to MT1389E , MT1389E will start the initialization check for Flash、E PROM、SDRAM, after everything is checked to be normal, it will start...
