Product Specification

■ Sems03

The SEMS03 is a high performance and fully integrated IC for multi-function LCD monitor/TV with resolutions up to full HD (1920x1080). It is configured with an integrated triple-ADC/PLL, an integrated DVI/HDCP/HDMI receiver, a multi-standard TV video and audio decoder, two video de-interlacers, two scaling engines, the MStarACE-3 color engine frame buffer, PIP/POP is provided for multimedia applications. Furthermore,3-D video decoding and processing are fulfilled for high-quality TV applications. To further reduce system costs,the SEMS03 also integrates intelligent power management control capability for green-mode requirements and spread-spectrum support for EMI management.

■NTP-3200

The NTP-3200 is a single chip full digital audio amplifier including power stages for stereo amplifier system. NTP-3200 is integrated with versatile digital audio signal processing functions, high-fidelity fully digital PWM modulator and two high-power full bridge MOSFET stages. The NTP-3200 receives 2-channel serial audio data with sampling frequency from 8 kHz to 192 kHz. It delivers 2x20W in stereo mode without heat sink.

The NTP-3200 has mixer and biquad filters which can be used to implement the essential audio signal processing functions like loudness control, loud speaker response compensation and parametric equalizers.

All the functions of the NTP-3200 can be controlled by internal register values via I2C host interface bus.

■TMDS351

The TMDS351 is a 3-port digital video interface (DVI) or high-definition multimedia interface (HDMI) switch that allows up to 3 DVI or HDMI ports to be switched to a single display terminal. Four TMDS channels, one hot plug detector, and a digital display control (DDC) interface are supported on each port. Each TMDS channel supports signaling rates up to 2.5 Gbps to allow 1080p resolution in 12-bit color depth.

Cable

Connect the Optical cable between the Digital Audio Out (Optical) jack on your TV and the Digital Audio Input on the Home Theater.

Connect only one Home Theater.

When following the connection above, the Optical jack only outputs 2 channel audio. You will only hear sound from the Home Theater’s Front Left and Right speakers and the subwoofer. If you want to hear 5.1 channel audio, connect the DIGITAL AUDIO OUT (OPTICAL) jack on the DVD player or Cable/Satellite Box (ie Anynet Device 1 or 2) directly to the Amplifier or Home Theater, not the TV. Please see the home theater’s user manual for more information.

Some HDMI cables may not support Anynet+ functions.

Anynet+ works when the AV device supporting Anynet+ is in the Standby or On status.

Anynet+ supports up to 12 AV devices in total. Note that you can connect up to 3 devices of the same type.

Notice

-Be sure to separate the power cord before disassembling the unit.

-Discharge the capacitors first when separating PCB’s with high capacity capacitors such as SMPS, X Main Board, Y Main Board, etc. (A spark may be generated by the electric charge, and there is danger of electronic shock.)

-Check that the cables are properly connected referring to the circuit diagram when disassembling or assembling the unit taking care not to damage the cables.

-Take care not to scratch the Glass Filter in the front.

-Assemble the boards in the reverse order of the disassembly.

4-1-2 Checkpoints by Error Mode

■ No Power

	- The LEDs on the front panel do not work when connecting the power cord.
Symptom	- The SMPS relay does not work when connecting the power cord.
	- The unit appears to be dead.
	The SMPS relay or the LEDs on the front panel does not work when connecting the power cord if the cables
Major	are improperly connected or the Main Board or SMPS is not functioning. In this case, check the following:
	- Check the internal cable connection.
Checklist	- Check the fuses.
	- Check the output voltages of the SMPS.
	- Replace the Main Board.

Troubleshooting

■ When the unit is repeatedly turning on and off

Symptom	- The SMPS relay is repeatedly turning on and off.
	In general, the SMPS relay repeatedly turns on and off by the protection function due to a defect on a board
	connected to the SMPS.
Major Checklist	- Disconnect all cables from the SMPS, operate the SMPS alone and check if the SMPS works properly and if
	each voltage output is correct.
	- If the symptom continues even when SMPS is operating alone, replace the SMPS.
	- If the symptom is not observed when operating the SMPS alone, find any defective assemblies by
	connecting the cables one by one.
