Plasma Display PD421
Audio input signal for PC/DVI, DT V, and DV D modes is entered into the audio processor IC, MSP3450G , and audio input signal for VID E O/S -VIDEO, and SCART modes is first selected in MUX 8851 a nd entered into the audio processor. As in other chips, the audio processor (MSP34 50G) uses the SCL and SDA line to control volume, and left/right balance and mono/stereo. The L/ R audio signal sent by MSP3450 is a mplified in the amplifier, TA2 024 (UAU1) and sent to the speaker. TA2024B support 10W(based on impeda nce 8Y ) of output for each L/R.
3. Trouble shooting 1) Diagnosing defective module If the power does not come on or if the module operates abnormally, check module defect. To do this, remove the rear cover and A/V B/D to reveal the module s logic B /D. The following figure represe nts the s/w on the logic B/D. � SW 2001

If the switch is set to internal signals, it will operate without external signals, but the screen will be displayed in full white. Therefore the module operation can be checked without the A/V board. Here, be aware that the pin 8 and pin 9 of the power B /D� s CN802(11p), which is located above the module� s logic B /D, must be shorted and the A/C power supplied in order for the module to oper ate normally. Pin 8 is marked as PS-ON below the connector (CN802). If module itself is tested and it does not power on or the picture is abnormal, the module is defective. When reconnecting the A/V B /D, make sure to change the switch to external signals. - The most common module defect i s the appearance of a black or bright vertical line.
