Haier CV1311B Service Manual

The Haier CV1311B supports the following video formats: 4:3PS and 4:3LB.

The DVD player of the Haier CV1311B is compatible with DVD, VCD, SVCD, CD, CD-R, CD-RW, JPEG, and MP3 formats.

The range for adjusting the Horizontal shift (H PHASE) is from 0 to 31.

The DVD signal format can be set to 0 for CVBS, 1 for YC, 2 for YUV, or 3 for hold.

To adjust the U signal delay, you can use the U DL function, which has a range of 0 to 3.

The SIF auto phase control filter is used to adjust the phase of the SIF signal, which helps in improving the sound quality and stability of the signal.

To perform a static convergence adjustment, input a crosshatch signal. Use the 4-pole convergence magnets to overlap the red and blue lines in the center of the screen and turn them to magenta. Then, use the 6-pole convergence magnets to overlap the magenta (red/blue) and green lines in the center of the screen and turn them to white. Repeat these steps to achieve the best convergence.

For dynamic convergence adjustment, move the deflection yoke up and down to overlap the lines in the periphery. Then, move the deflection yoke left to right to overlap the lines in the periphery. Repeat these steps to achieve the best convergence. After adjustment, fix the wedge at the original position, fasten the retainer screw of the deflection yoke, and fix the 6 magnets with glue.

The MTK1389D IC consists of RF, SERVO, DSP, DECODE, VIDEO DAC, and AUDIO DAC.

The initialization process for the MTK1389D IC involves resetting the IC, receiving a clock signal from the crystal oscillator, and then performing checks on Flash, E2PROM, and SDRAM. If these components are normal, it proceeds to initialize the built-in Audio DAC, servo, and motor Driver IC. If all parts are good, it sends a signal to the motor Driver to drive the servo system, pick up the disc, and check if it is a CD or DVD format.
