SAMSUNG WS-32Z316 TROUBLESHOOTING

CXA2171Q [COMPONENT SWITCHING] DIAGNOSIS

• Component 1 & 2 input operation.   (Y: 0.7Vp-p)
• IC distigushes between SD/HD [31Khz, 33Khz] signal formats.
• Defect:  THE SCREEN IS PUSHED TO THE RIGHT IDE OF THE PICTURE OR THE PICTURE IS DIVIDED INTO TWO ON THE SCREEN.

1. Power supply 5V.
2. Check for input defects: Y | Pb | Pr signal.
3. Check for output defects: Y | Pb | Pr |, H/V signal.

MST 9883 Diagnosis

• This receives the component signal, which is equal to or higher than 480p, detects Sync and decodes the signal.
• If the signal color is out of order or noise appears  in the color bar pattern, check the R|G|B output cable.

1. Power supply 3.3V
2. Check for input detects: 480p, 720p. 1080i Y/Pb/Pr signal.
3. Check for output detects: R|G|B 24 BIT H/VClock.

DNle_SPD41 Diagnosis.

This removes noise signals from the signal processed by the EAGLE IC for better visual quality.It provides a clear and near natural color picture.  Defects on DNle are rare.

1. Power supply: 1.8V, 3.3V
2. Check for input defects:  R|G|B 24BIT H/V/Clock.
3. Check for output defects:  Y/Pb/Pr H/V

-----------------------------------------------------------------------------------------------------------------

CXA2165 DIAGNOSIS

• This receives the Y |Pb | Pr input from DNle and outputs V/H Drive E/W, and controls the operation of  ABL.EHT. If V-Drive output fails, the IC is defective.

1. Power supply: 5V, 15V
2. Check for Input defects:  Y | Pb | Pr H/V
3. Check for output defects:  R/G/B, ABL, EW, V/H-Drive.

--------------------------------------------------------------------------------------------------------------

MSP4440, AUDIO PROCESSOR Diagnosis.

• This receives sound IF signal from the Tuner, and external input signal 1/2/3/4, and performs signal processing.  It can input and output 12S signal for Audio Delay.

1. Power supply:  5V, 8V.
2. Check for Input defects:  Sif, Scart 1/2/3/4
3. Check for output:  Lt | monitor Out.

---------------------------------------------------------------------------------------------------------------------

TDA7297; AUDIO PROCESSOR Doagnosis

• This receives the signal from the audio processor [MSP4440] and outputs the signal in 10W + 10W sound.

1. • Power supply:  16V.

2. 
   

   • Check for input defects:  Lt | Rt.
3. 
   

   • Check for output defects:  L+, L-,
4. 
   

   1. 
      

      •                                   R+, R-
