HT-BD8200 is a Blue-Ray Home theater system.

THe unit has power block (SMPS), Main Block (Main PCB), AMP block (AMP PCB) and other block (Key, Front, Side Jack,

Rear Jack).

1) Power Block

SMPS power block has tow cables.

24pin connector is for Main PCB (VFD power, 12V, 5.6V) and PVDD power for AMP PCB. It has a two trans.

2) Main Block

Door Assy (with Slim deck which can play BD/DVD/CD disc) is connected to Main pcb.

The signal from the Door Assy (slim deck) is going to BCM7601 main system IC.

It decoding digital signal and send the decoded digital video signal to TV, analog video data to video amp ic and digital

(PCM) sound data to AUDIO DSP IC. Audio dsp IC is making effected digital sound.

3) Amp Block.

PWM modulator is changing the PCM digital signal to PWM signal.

This signal is transfer to AMP IC and amplified.

After the amp IC there are low pass filter to cut the delivery frequency which is used PWM.

4) Other Block

Key pcb (Function & Volume pcbs) are connected to front pcb. Front (VFD) pcb is connectoed to Main Board.

Touch Key pcb is contorled by Main Micro controller.
