Reason Of Change
# Problem : After 20~30 min of heat run , component image has distortion in position or
size. Sometimes image is shifted or duplicated . The distortion can be induced after
changing the resolutions on component mode. Once image distortion is induced, all input
image have distortion.
 # Model : 32LP1DC-UA, 32LX3DC-UA, 32LX3DCS-UA
 # Cause : IIC data between ADC and CPU are corrupted by the lack of IIC Setup/Hold
time.
 # Corrective action : Change the chip capacitor of IIC from 330pF to 470 pF
